I want to recommend the Staples Carder Mesh Office Chair. This particular model is fairly compact taking up little room while offering a very comfortable experience. The chair arrived just a day after I ordered it When I realized I would be putting it together I was a bit concerned I would do the job right. No need to worry; very simple with the best instructions I have EVER seen included with a product. The chair is very comfortable with the number of positions for the seat back and tilt pretty much guaranteeing you'll find that perfect position. Rollers work well on carpet. Very happy with this chair.
I purchased 2 chairs. One of them was perfect with assembly required as anticipated. The second chair was identical but the hand nut that secures the back of he chair had threads that were damaged. Didn't look like a return so my guess is poor QC. Rather than return the chair we ran a die over the thread to clean it up. Problem solved.
I did a lot of research before I bought this chair. Easy to put together and the price was right. I am retired and spend a lot of time sewing for charity so the lumbar support was a key to my choice. I also have 4 machines ( serger sewing embroidery) that sit on a table a bit higher than normal so the highest setting on this chair puts me a the right height and helps me maintain good posture.
I purchased the Carder Mesh office chair. Love it! I was needing a chair with more lower back support.....this chair is great for that! I also wanted a chair that was cool....had one previously that was very warm. The mesh on this chair makes it a cool chair to sit in!
