Why You Need To Buy a Good Office Chair in India

Buying office chairs for a business should be an easy task but as it turns out, it can be rather confusing. With the myriad of options for fabric, back support, design, and function, it is a dizzying number of choices.

One of the first steps in selecting the right office chairs is to identify what the chair will be used for. When you identify the purpose of the chair, you can zoom in on the actual functions needed. Is it for the reception area, for the cubicle, for the computer workstation, for the telemarketer, or for the manager? Depending on the person using it, you have a pretty good idea of what the chair should be. For example, a manager might need a high back leather chair and not a secretary office chair or a office reception chair. If it is for a computer desk, you’ll want to match it up with computer desk chairs. If it is for a conference table, buying conference table chairs would be more suitable. There are many things that need to be look before you buy the best office chair in India, in this article we will be discussing what features and qualities you should look before you purchase an office chair.

What to look for when buying an office chair in India

top office chair in IndiaAs for the design, you’ll mainly need to know whether a user is expected to be sitting on the chair for many hours in a single day or less than an hour a day. This goes along with the purpose of the chair. As far as functions go, there are a couple of features you’ll want to consider. Here they are in no particular order.

Do you need the office chair to wheel around easily? For example, an office computer chair might need to wheel around to access file cabinets, papers on the main desk, or roll over to answer the telephone.

If so, what kind of chair castors would you need? Will the chair be on hard floors, carpet, wood, etc.

Do you need flexible height, back, and tilt adjustments?

Certainly, selecting a designer office chair with all the bells and whistles will be considerably more expensive as compared to a reception chair with no castors for mobility.

Lastly, beware of buying from some discount desk chair retailers. Setting up shop online is quick and low-cost. This leads to irresponsible business practices where some companies will slash prices in the bid to win sales at the cost of customer service and proper order fulfillment. Doing business with a company that is around and doing business for many years is a sure sign that they will grow along with you as your business grows from strength to strength.

The quality and comfort of your office chair affects your health and productivity. Office chair seat height should be easily adjustable. A good office chair will have support for the lower back. If you want to do wonders for your back, make sure you buy a chair with a reclining seat back. With so many options, though, picking the right one for you isn’t easy.

  • A pneumatic adjustment lever is the easiest way to do this.
  • Some of the better ones will even have an adjustable lumbar support that allows the user to fit the chair to their lower back.
  • When doing so, you can have an easier time staying comfortable while you sit in your chair.
  • This graphic from Office Chairs Unlimited can help.
  • A seat height that ranges from about 16 to 21 inches off the floor should work for most people.
  • This is important in preventing back strain that can worsen and become sciatica, a condition which can be debilitating.
  • In the long run, you will develop fewer problems if you have a reclining seat back.

Adjustability in office chair
Most of the pointers are ones we’ve noted before in our guide to ergonomically optimizing your workspace: Arm rests should keep your elbows bent 90 degrees, seat height and back rest height should be adjustable, etc. This allows the user to have his or her feet flat on the floor, with thighs horizontal and arms even with the height of the desk. Almost all office chairs have a height and arm adjustment; however, these are not the most important adjustments to look for when shopping for an office chair.

ergonomic office chair IndiaIf you sit at a computer, you will probably have your arms and hands on your keyboard. The graphic lays it all out visually so you can see what you need to look for in an office chair at a glance (or even print this out and take with you when chair shopping). You should be able to position your backrest in a way that suits your task. The seat should have enough width and depth to support any user comfortably. The best office chairs have at least five adjustments with some having up to 14 different adjustments. But, while on the phone or sitting around chatting, you will want armrests.

Lumbar support in office chair
If the backrest is attached to the seat you should be able to move it forward or backward. Usually 17-20 inches wide is the standard. It’s essential that the chair has a backrest with an appropriate size and shape, to support the lower and middle back properly without restricting arm or shoulder movements. With a couple of well-placed armrests, you can remain comfortable and not worry about where you need to put your arms. A locking mechanism that holds it in place is good so that the back does not suddenly tilt backwards.

The depth (from front to back of the seat) needs to be enough so that the user can sit with his or her back against the backrest of the ergonomic office chair while leaving approximately 2 to 4 inches between the back of the knees and the seat of the chair. The backrest should help you to maintain the natural S-shape of your spine when you’re sitting. People working on large desks need the freedom to move from one end to the other without having to stand. A backrest that is separate from the seat should be height adjustable, and you should be able to angle it to your satisfaction as well. In order to find the right office chair, you need a seat that is wide and deep enough to fit your body.

Seat depth
Tilting the backrest allows you to adopt different postures, e.g. upright, or semi-reclined. A proper office chair should have soft rubber wheels especially if your desk is on a solid surface. Most people who work at a desk all day suffer from lower back pain the most. Big and tall chairs are a great option for larger body types. When you sit on a work chair, the angle between your thighs and back should be around 95 to 105 degrees so that your abdomen and chest are open and not compressed.

Hard wheels could ruin your soft carpeted floor; use a rag to avoid damages. This is due to sitting in a chair that does not have adequate lumbar support. A shallower seat is preferable by employees who are not very tall. An ergonomic chair can easily turn into just a ‘normal’ chair if it has never been adequately adjusted for its user. Ideal office chairs should have an armrest that has the elbow on a vertical level with your forearm.

Powerful wheels of office chair
When buying a good quality office chair, you need to look for one that includes this types of support for the spine and lower back area. To test the chair, sit up straight, with your back against the backrest. So, familiarize yourself with the chair features either at the showroom or when you first set-up the chair in your workspace! This is the recommended position to reduce arm strains. Some chairs will have an adjustable lumbar support feature that will allow the user to adjust the chair to meet their own individual needs.

Office chairs 2017For maximum comfort, look for a chair that leaves 2-3 inches between the back of your knees and the seat. You are advised to go for a chair that also has adjustable armrest to suit different people of various heights. This will help to prevent back strain which will often lead to sciatica if left untreated over time. For reference, a standard seat is about 20″ in depth. Many employees complain of back pain when sitting all day at work.

This typically fits most users unless you are on the smaller or larger side. An office chair with lumbar support helps alleviate this issue, so you should seek chairs with this feature. Whether you’re looking to buy a chair for yourself or for an entire office, it can be tricky to find a chair designed to adequately accommodate the wide range of shapes and sizes people come in, or the wide range of sitting positions people use throughout the workday. Some designs even have adjustable support, allowing your employees to fit the chair comfortably to their bodies. The truth is there is no ‘best’ chair that will perfectly suit everyone, but there are some features that you should look for in order to help you find the best chair for your office. Additionally, you can find models with firmness control that make the lumbar support sturdier or softer. Continue reading 

Improving battery life of iPhone and choosing power bank

The biggest bottleneck in the iPhone (or any smartphone for that matter) is the ever worsening battery life. While computing is a rapidly growing area, battery technology has seldom improved at all in the last decade or so, and is now struggling to provide adequate power for the hungry components that are in the latest iPhones and other smartphones. Today we have power banks that can be used to charge your mobile phones and tablets while you are away from home and office. You still need to know how to efficiently use our smartphones and how to save battery life so that it can be used for longer duration. We will be discussing about top power banks that can bought in India and how to choose the right power bank for your smartphone later in this article.

Is your iPhone’s battery life actually bad?

iphone battery improvementWhen most people compare the battery life of a smartphone (an iPhone, Android, Blackberry etc) to that of a feature phone, they find the feature phone to have a much better battery life; going for days or even weeks without being charged, while their smartphone counterparts can barely make it through the day on a single charge. But while smartphones consume more power (bigger screen, higher pixel density, faster & more powerful processor etc) they also have much larger and more high quality batteries to counter it.

The reason why smartphones often appear to have poor battery life is because we basically use them as computers. We tend to use smartphones much more than we do ordinary phones, which gives the impression that the battery doesn’t last as long. So consider this before you read on…

Turn Down Screen Brightness

Screen brightness is probably the single most important factor when it comes to saving battery life on your iPhone. For best economy/performance ratio over a wide range of environments your iPhone’s brightness should be set at about 50%. [Note: If your iPhone is jailbroken this tweak will make adjusting the brightness easier]. You should also turn on the ‘auto-brightness’ switch, which is located beneath the brightness slider in the preferences app. Auto-brightness will dim the display when it’s dark so it’ll be easier on your eyes (and save power) and will brighten it when it’s light so you’ll be able to see the screen easier.

Turn off Bluetooth

Bluetooth sucks quite a lot of power, so turning it off when not in use is well worth it. Besides, bluetooth on the iPhone isn’t all that useful anyway. Due to Apple’s walled garden you cannot send/receive photos/videos/music via bluetooth like you can with most other bluetooth enabled devices – So unless you regularly use a bluetooth wireless headset you will likely never use it. To turn bluetooth off to to the preferences app, go into the general section then go into the bluetooth section.

Turn off WiFi when not connected to a network

Turning off WiFi when your not connected to a network (ie: when you leave your house) saves a significant amount of battery life, however most people either won’t remember or can’t be bothered turning WiFi off whenever they leave the house. It is worth keeping in mind though, for times when you know you’re not going to have access to WiFi for several days or more. When you’re on a road trip you won’t won’t your iPhone wasting battery life by attempting to connect to every Internet Cafe you drive past, will you?

Turn off Fetch Email

Fetch email pretty much checks for emails periodically, just like your desktop email client checks for emails. While it’s great to not have to worry about checking emails, fetch email drains battery life (and cellular data when your not on WiFi). If you’re not willing to disable fetch email completely, you could turn down the intervals at which is checks, so instead of checking every five minutes it checks every hour for example.

Poor Reception = Poor Battery Life

Poor or choppy cellular reception takes a huge toll on the battery life of mobile phones, and iPhones are no exception. In many cases there is not much you can do about poor reception, however if you live in an area that has consistently poor reception you should seriously consider moving to a different carrier or purchasing a signal booster. It will make worlds of difference. Oh, and be sure to turn your iPhone off or switch it into airplane mode when your on a plane, because if you don’t the phone will use much energy searching for a network that it can’t reach.

Download all Software Updates

There can be bugs in the software of your iPhone that cause excessive battery drain and heat – These bugs usually occur just after a new phone model or major operating system has been released. Downloading all the software updates for your iPhone as soon as they come out will fix bugs which may fix battery life issues. If you are suffering from terrible battery life and heat issues on your iPhone it’s likely that it’s just a bug in the operating system.

Keep your iPhone out of the Heat

Being sensitive to excessive heat, the iPhone’s Lithium Ion battery will discharge faster when exposed to temperatures above around 45C – And if exposed to these temperatures for extended periods of time, could even reduce the capacity of the battery. Therefore you should keep your iPhone out of direct sunlight, parked cars and hot appliances.

Calibrate your iPhone’s Battery

While calibrating your iPhone’s battery is unlikely to technically increase its battery life, it will make the battery meter more accurate. This may make the battery life of your iPhone seem longer because the battery won’t run down real fast then stay on 1% for ages. Rather, it will run down slower so the battery will be flat on exactly 1%.


Choosing a power bank for your iPhone

power bank in India for IphoneThere are many types of power banks available in India and they differ in features, size, type and price. If you are looking for a great power bank for your iPhone then you must read this guide. You might assume all power banks are much the same thing, but you would be wrong. Capacity, shown as a milliamp hour (mAh) figure, is a rough indication of the charging capabilities – the higher the number, the more power it can deliver to your device before the power bank also runs out of juice. The main spec to look out for in a portable battery pack is capacity, which is measured in milliampere-hour (mAh). The capacity of your device’s battery is also measured in mAh, so loosely speaking, if your phone has a 2,000mAh battery, a 2,000mAh battery pack is able to recharge it fully once. Ensure that you buy from a reputed brand. You can get compact power banks that will charge your phone once, slightly larger portable chargers that might offer two or three charges, or high-capacity banks that can charge your phone in excess of 10 times.

  18. Garden furniture

This is some of the most sought out items by burglars, these are the items that homeowners have to be extra careful about.

How to burglars decide which house to rob?

Burglars will often decide based on the “curb appeal” of a certain home. A house is more desirable to burglars if the lawn is not kept clean, if the house appears to be abandoned most of the time. If the lawn is often clean, this could imply that the homeowner is always near the home or is paying attention to their property which makes it less appealing to burglars.

An overgrown lawn on the other hand will appear to be inviting to burglars, they will think that there is a higher chance no one is inside the property. Corner houses are also not often targeted when compared to houses in the middle of the block because they will appear too visible. Townhouses have poorly secured sliding glass doors are also a target for burglars.

How to protect your home?

A beware of dog sign

Put a beware dog sign outside the gate even if you do not have a dog- In order to make it seem real put a dog bowl and chain out by the back door; this will fool the burglar better. There is no need to put in motion-sensitive electronic dog barking devices.

Using top quality deadbolts

A good quality deadbolt on the front door is essential for preventing burglar to try to break in your home. When you buy a door locks for entry door, make sure its ANSI grade 1. There are many cheap quality door locks which is not good and can be easily pick by burglars. Nowadays door locks have improved lot just like a smart phone. If you are looking to buy best keyless door locks then make sure it is a deadbolt and not just lock.

Security Cameras

Purchase security cameras- avoid purchasing the low-end Radioshack kind though. They tend to have red blinking lights and low an absurdly low quality span, so burglars can easily detect the light, know he camera is cheap, and work his way around it.

Avoid obvious hiding places

Avoid hiding items in the dresser or lingerie drawers, under the mattress medicine cabinets, night stands, anywhere in the living room, dining room and bedroom because this are the first places that the burglars will try to look.

Some good hiding places?

A good hiding places would include the attic, the basement, the children’s bedroom, the broom closet, the kitchen. You can keep some of the valuable jewellery in food containers and put them in a high shelf. The burglars will have a harder time reaching them and will not usually think that important items are tucked away in a food container.

Get a decoy box, lure them out.

Have a decoy box- put some beautiful jewellery box near your night stand, put some fake jewellery in them. This will stall the burglar for a little longer. The goal is to lessen their time and distract them from finding the real items.

Why You Should Use Deadbolt

top deadbolt door locksHighly rated locksmiths tell our team that deadbolts represent a higher level of protection than a doorknob’s pin tumbler lock, especially if: The bolt is made of hardened steel. A deadbolt is a type of lock with a steel bolt that extends into the door jamb and strike plate of a door frame. This is a simple deadbolt lock which is activated or opened from one side through a key while there is a thumb piece in the interior side. If an intruder breaks the glass, they don’t need to unlock or open the door. Double bolts require keys to open the door from inside or outside.

  • The most common type is the single-cylinder deadbolt, operated by a twist knob on the inside of the door and a key on the outside.
  • These types of locks are used in the doors which do not have any breakable glass near the thumb piece turn.
  • The opening from the broken glass is big enough for them to enter anyway.
  • Because of that, it’s important to know that a double deadbolt can be problematic or downright dangerous if you need to escape a house fire or other emergency, unless you keep the key near the door or in the lock.
  • Some people prefer the double-cylinder deadbolt, which doesn’t have a twist knob and requires a key for operation both inside and outside the home.
  • As the intruder might break the glass, turn the knob and enter in.

Take heart though: modern, tempered, double-glazed windows are pretty difficult to break, and it will make quite a noise! Single-latch locks are produced by a variety of manufacturers and have slightly different designs, but they serve the same function and offer similar security measures. The deadbolt is definitely a better lock than a standard doorknob lock. A deadbolt is more about resisting kicking open or using a credit card to slide in and raise the bolt.

Therefore, a double-cylinder lock provides no additional security, but does cause inconvenience and a safety hazard for you and your family. Single-latch locks are spring-loaded and have rounded metal ends that protrude from an open door. It is harder to break down or pry open the door with a deadbolt, since it is thicker and goes further into the frame. It’s not so much about being harder to pick, as the lock mechanism in it is going to be extremely similar to a normal door handle lock. The fact is that double cylinder deadbolts are only necessary for specialized applications such as doors with glass on or near the deadbolt.

The latch retracts as it slides past the door frame and releases, securely mounting within the hollow plate on the adjoining door frame. But really, if someone wants to get into your house, two locks instead of one is not going to stop them. You don’t actually need to remove your lock, because it only replaces your deadbolt thumbturn. Intruders can break the glass, reach in and release the thumb turn on single-cylinder deadbolts. Some people do lock the deadbolt when they’re at home but this is not advised because if there’s an emergency you can’t get out of the property quickly.

Consulting with a variety of potentially ‘targeted’ people has taught me a lot. It’s super easy, even fun to install, and takes practically no time at all. Since double cylinder deadbolts require a key to lock or unlock both the exterior and interior of the lock, ultimate security is enforced. If you do want to lock a deadbolt, you should have a key in the back of the deadbolt to give you an easy exit. One of the things I learned was ‘their’ ability to literally walk right into 90% of the homes in America, leaving no trace of their access.

Then you’ve got a Bluetooth-connected, motorized deadbolt that can remotely lock and unlock the door when you press a button on your phone. But be careful. I have some personal experience with this (in the past), for example I have had things ‘replaced’ while we were gone, in attempts to ‘intimidate’ me or make me insane, with absolutely no signs of forced entry. Or automatically lock as you leave, and unlock as you approach. Many communities prohibit the use of double cylinder deadbolts because they may cause serious problems in an emergency where a quick exit is essential.

The most common lock function for exterior door hardware is a keyed entry function. Locks with this function have a keyed cylinder facing the outside of the home and a thumbturn on the interior. When the door is locked, it can only be opened with a key from the outside. When the knob is turned from inside the home, and the thumbturn is unlocked, the door will open freely.
