Great chair!

from California – Verified Buyer

I originally wanted a kneeling chair after trying a Varier kneeling chair. It was comfortable, but I felt I needed more of an angle, and it was way over my budget. I did a lot of research and settled on this one. It doesn't look fancy, but the steel construction I felt would last (people buying wood ones compained of them breaking). I am 5'8 at 145 lbs, and at the middle setting of this chair is perfect for me (the angle is a perfect balance for weight distribution on my rear and knees). I also love how my feet dangle above the floor. It is very relaxing. My husband, who is 6'3 at 210 lbs, thought it was comfortable at first. However, because he is so tall, his shins and not his knees rest on the pads, and he compained it was causing his feet to go to sleep. It was just too small for him. The fabric is cheap, but that's fine since the chair is inexpensive. The pads have a wood base, so reupholstering them would be easy once the fabric is worn down. Great shipping from Wayfair as usual.

Great chair for good posture

from Cleveland, OH – Verified Buyer

Although I cannot use this chair for an extended period of time (like all day), it is great for taking stress off your lower back and keeping your shoulders straight and relaxed. I had a total knee replacement so even though your weight is distributed between your knees and rearend, I still find long stints on my knee kind of bother me. Other than that, it works very well for the purpose intended.

as advertised!

from Powder Springs, GA – Verified Buyer

Easy to order, received quickly. Easy to put together and even came with the tools needed to do so. I have back problems and sitting in a chair is one of the most painful things to my injury. The design of this chair, especially with the adjustability, has enabled me to sit for long periods and work. When my back is particularly bad I have even been know to pull it up to the dinner table! No regrets here.

Works Well

from Medicine LAKE, MT – Verified Buyer

I have no had this long but putting it together was easy to do. Sitting in it is comfortable and though I have not done a stretch past 20 minutes it seems comfortable. I notice I sit up straighter while in it too. I have no problem with the height settings and I am 5' 3". The cushions are very comfortable as well. Very pleased with the purchase.

Pretty good

from Maumee, OH – Verified Buyer

My husband and I are within an inch of each other in height and we use this chair in radically different positions. I like it almost all the way up, he likes it almost all the way down. Range is great for multiple users, cushions are thick and comfy. My only gripe is that it's not very attractive. Would have like to see it in wood or with lighter cushions to spice it up a little.

Comfortable way to work

from Huntersville, NC – Verified Buyer

This chair takes a couple of days to get used to if you have been sitting in a standard desk chair. But once you do, it improves your posture and I feel less fatigued at the end of the day.

assembled easily and works well

from Mokena, IL – Verified Buyer

Good product. my only complaint is that the design prevents front casters from turning easily when seat is at tall heights. Otherwise very nice value

Great Buy!

from Rathdrum, ID – Verified Buyer

It is very comfortable. Just what my back needed. Not easy for a 76 year old and 83 year old to assemble but we did it. The end result was worth the effort.
