Great chair for the price!

Jessica from Secaucus, NJ– Verified Buyer

I caught this chair on a sale and decided to go for it; it's been hard for me to find a reasonably priced desk chair that isn't poor quality.

I'm happy to say that I love this chair so far! It was SUPER easy to put together (I probably could have done it without the instructions), lifts up and down easily, and is surprisingly comfortable! I'm also glad that it goes pretty low -- the desk I have is fairly low and has a keyboard drawer, so I couldn't get anything that had arms.

For the price I paid, I'm very happy with it. I am sitting in it now to write this review, so I'm looking forward to comfortably using it to work from home when necessary!

Perfect task chair!

Denise from Englewood, CO– Verified Buyer

I would be disappointed if the sale price point wasn't what it was, but for the intended use of getting out of a huge man chair at my desk as quickly as possible for finals and paper writing it's perfect. I couldn't stand another day using a chair someone thought was "fine" for me when I could hardly function let alone be proficient at the end of the semester. I'm not sure I'd use this chair for long periods at a time in the future, however it's well built, easy to assemble in just a few minutes- and was a long overdue necessity my partner was refusing to acknowledge. The purple is a nice shade and just purple enough to make a statement.

Christy from Trussville, AL

Actually, this is a very comfy chair. I specifically needed an arm less chair to fit under my desk, and this one is perfect. The seat has enough cushion, and the back is soft and flexible. I did not want orange, but that was the only color left, and I am glad the color did not keep me from this purchase. Very happy!

My go quilting chair

Mim from Michigan

I purchased this chair to take to sewing retreats. It is comfortable, and light weight, which is what I wanted. I would recommend this chair for a home office or for a crafter.

SpaceFlex Mid-Back Task Chair

Paulette from Highland Village, TX– Verified Buyer

Great little chair to use in my sewing room. Very comfortable. My quilt shop sewing room has 12 of these chairs for the quilters to sit on. I was able to sew all day without any back pain, so I bought one for my home use. Great value and free shipping!!! Fabulous!!

great chair

Linda from Davis, CA

Looking for a task chair for a long time didn't have arms, the cost was a factor as well. My husband has back problems so sitting can be a problem for him this chair has the hard back that contours to your back with a cushion seat. I would buy this chair again. Easy to put together and sturdy. Great chair

Wonderful task chair!

Michele from Jeffersonville, IN

I bought my first chair for my jewelry design work station. Loved it so much, I bought another one! Amazing stability and comfort with an equally amazing low price. Love these chairs!

Megan from Urbandale, IA

This chair has no frills, but it's decently comfortable, easy to put together, and true to description. It also shipped very quickly. The wheels roll well on carpet, too. Overall, I'm satisfied with what I got for the money.

Comfy chair...

Katherine from Largo, FL– Verified Buyer

After a slight mix up - wrong color chair was sent...manufacturer's error, box was marked wrong - the correct chair was delivered. I'm thoroughly pleased with this ORANGE office chair. It's the right size, and color..nice cushioned sear, seat back is supportive and it moves easily on hardwood floor AND carpet. Wish i had ordered a chair with arms (MY mistake). Overall, i am very happy with my purchase.

Yay colors

Angela from Milwaukee, WI– Verified Buyer

I have this chair in orange and purple; Plan to get green too. It's a good chair regardless of color, but also, it's awesomely fun to get multiple colors for a little more "pop" to my office & conference area. One of my chairs is over a year and a half old, and still looks good. Unlike other chairs that start squeaking or falling apart after that amount of time.
