The design of the backrest, without an adjustable lumbar system, spreads nicely throughout your lower back. The Cosm is also one of the chairs that we tasked that gets better as you recline back into it. We found the best support, which rated at medium-strong, was felt from about 50 to percent recline. With the tall backrest design, it is a good option for those who like to work in a reclined position.
Eighth on our list is the Eurotech iOO chair , with a score of 78 out of At first glance, the iOO is easily mistaken for the Ergohuman series, with similar features throughout. When seated in an upright position, the iOO has a medium to medium-strong lower support. Like the Ergohuman series, the lumbar system protrudes beyond the upper portion of the backrest, hitting your lower back even when sitting slightly forward in the chair.
The mesh upholstery does a better job of spreading throughout the lower back than the LE9ERG, featured at number one on our list.
If you are looking for a wider range of lower support, this could be a better option. The lumbar support is also height adjustable, which allows you to fine-tune where it provides the most support. As you recline in the chair, the support remains fairly consistent, with medium support even when in a fully reclined position. The motion of the recline allows for the lumbar support to move minimally, offering more consistent support for the lumbar region than that of the Ergohuman series.
The final product on our list, the Humanscale Liberty chair , is the third Humanscale product to be featured on our list. With a score of 77 out of , the Liberty features a similar back design and function as the Diffrient Smart chair. When seated in the upright position, the Liberty chair offers medium to medium-strong lower support. Like the Diffrient Smart, the initial pivot, when arching your back and slightly reclining, increased the lower support.
The biggest difference between the Liberty and Diffrient Smart was that once you reclined beyond 50 perfect, the Liberty only had light lower support. Not all users task the same way. While some work in perfect posture with their back up against the chair, others tend to slouch.
Maybe you like to lean to the side when you type. This is the quickest way to failure, as most habits can be hard to break. Finding a chair that provides proper support for the way you sit, is likely to improve your support while seated. Do you like to recline in your chair?
Is this something that you spend a lot of time doing? If you are taking a lot of phone calls, in meetings or even working from this position, proper support while reclined can be important if you have lower back issues.
Depending on how the recline function moves on your chair, the lower support can change in various ways. While not always true, having a lumbar support system that is height and depth adjustable can be important. Having depth adjustment will allow you to add and reduce the amount of pressure applied to your back. Depending on the amount of support needed, this can be a nice feature to have. Depending on the type of tasks you perform in your chair, you may want to consider how the backrest and lumbar moves with you.
If you are doing a lot of twisting and reaching, having a backrest that moves with you and provides continuous support is good if you really need a lot of lower support. We have seen a lot of different types of backrests that will provide this function.
From the entire backrest bending and flexing, to only the lumbar support automatically adjusting in depth. The last thing to consider is what type of material the lumbar and backrest are made from.
Certain types of materials will flex more, spreading out the support through your back. We have seen upholstered lumbar systems with padded backing that can feel more stiff and will focus more on a certain area. Depending on your needs, this type of focused support can be good or bad. Depending on the amount of support you require and where you need it most, finding a chair with excellent lower back support is always a good idea.
Each chair in our list offers, at a minimum, excellent lower back support for long hours of tasking.
