Great chair/stool

Carrie from East Hampton, NY– Verified Buyer

Love this stool, is comfortable for someone who has to sit at desk and work long periods of time and also tucks away nicely under desk which is great because my space is limited.

Comfortable and well padded.

Brett from Toledo, OH– Verified Buyer

The chair is sufficiently padded and comfortable, however, the build quality doesn't live up the purpose.

Most people are buying a knee chair to put themselves in better posture when sitting at a desk for long periods. In theory, this chair does that. It opens the hips and helps to align the shoulder over the hips preventing the awful head forward, rounded shoulders seen when sitting at a computer. However, the build quality doesn't live up to the purpose. The weld on the seat bracket is not plum (on mine) so my hips tilt down the right 3 -5 degrees. Those causes my upper body to tower to the right. Can only assume this is going to cause other long term use issues.

Assuming this chair was built correctly I would give it 5 stars in a heartbeat.

Posture Chair

Ace from Chula Vista, CA– Verified Buyer– Top 1000 Reviewer

We had this chair in the convent during our evening adoration which prompted me to buy. i wasn't so much aware that there were wheels but it's still good. Helps with the posture and reminds you to sit properly. I like it though sometimes because of the smoothness your behind slips down. Otherwise a great chair if you want to be reminded to have the proper posture while sitting.

Encourages good back posture

Case Crenshaw from Chimayo, NM– Verified Buyer

I use this in the office, so it is used for several hours at a time. Other stools would cut off the circulation in my legs. This one is quite comfortable, quality was as good as I was hoping for and it was very easy to assemble and even a couple of extra bolts were thoughtfully included.

Great Product

Monika Bishop from Hendersonville, TN– Verified Buyer

I ended up purchasing two of them. They are very comfortable, and hide away under the desk easily. Good cushions, still look like new after a year.

Helps my back!!

Cecelia from Lafayette, IN– Verified Buyer

Easy to put together and great for my back. Encourages good posture, too. I use it at home at my writing table where my laptop is.

ruth from hood river, OR– Verified Buyer

Wayfair had the chair I wanted at the best price and shipping was free. It shipped right away and arrived before Christmas. Wayfair rocks!
I have this chair and use it at my office and love it. I sent one to my son for Christmas and he loves his too!

back comfort

Phyllis Cardillo from Mercer, PA– Verified Buyer

This is a very comfortable alternative to flat-seated chairs, especially if you are experiencing back problems. It is easily adjusted and the casters allow for smooth movements back, forward and sideways. The chair is well constructed and very reasonably priced - do not hesitate to purchase.
