  • Comfortable and sturdy ergonomic chair
Color: T40 Se | Terracotta
During the pandemic I had to work from home and spent a lot of time with a IKEA MARKUS chair. I chose it since it’s known as a good ergonomic office chair, but it was not for me. Although it has built-in lumbar support, I had back pain. I tried to use a lumbar support pillow, but it didn’t help much. I’m not an exceptional case because there was a reddit thread about the back pain with the chair. Also, the chair didn’t provide a proper range of height (I’m 5' 8” tall). I had to use a footrest, too. This chair is amazing. I can adjust the chair’s headrest to fit into my neck, and armrests to make my arms at the right position. The chair mesh back makes me cool and comfortable, but it is sturdy enough to support my lumbar. The adjustable height range is much wider than my previous one. I don’t need to use the lumbar support pillow or the footrest. After spending some time with this chair, I don’t feel any back pain anymore. I’m happy with my purchase. ... show more

  • Great looking chair with cool functions
Color: T40 Se | Terracotta
This chair looks amazing and also has many features that you don’t normally see on other chairs, the arm rest can not only raise up and down but also can tilt inward and outward, back side can tilt as well. There is a locking feature so if you don’t want tilt, it can be locked. It has a great lumbar support and neck support. Head rest is adjustable based on your neck position. I’ve had a bad neck for years due to working in front of computer while slouching, this chair helps to correct my posture and can keep my back and neck straight. The seat cushion is very nice and seems durable. I like the material. It was pretty easy to put together. Overall I recommend this chair for the office or study room. ... show more

  • Proud of this new home office look - excellent chair
Color: T40 Se | Terracotta
I've been working from home much more often lately and wanted to build a space in my apartment dedicated to remote work. I gotta say that I'm loving how the chair adds to the look of the space. The colors go together really well with the other furniture; I appreciate that the chair doesn't look like one of those black/gray serious kinds or bulky ones with too much padding. The chair is super supportive in terms of the wide width of the seat and the tilt-and-lock adjustable back, headrest, and armrests for customization - hoping this helps resolve the back pain issues I've been having recently. It took about a week for the chair to be delivered. Assembly was pretty straightforward and took less than 20 minutes. All in all, an excellent product and happy purchase! ... show more

  • The perfect, comfortable, and convenient chair!
Color: T40 Se | Terracotta
I’ve been looking at desk chairs for awhile now and finally decided to get this chair! I’m so happy with my decision and it’s been a wonderful addition for me. The color is not too bright and suits my desk area great. You can adjust the height, tilt/lean, and even move the arms back and forth as well as left and right. The wheels are smooth and I haven’t had issues with any of the joints and adjustable areas. Setting up the chair was a simple and easy process. The cushion is a firm but comfortable material, perfect for sitting for long periods of time. I think this chair has an impressive design and may be the one you’re looking for! ... show more

  • Not able to reach support team
Color: T40 | Gray
Chair is ok. Ergonomically fine. Seat is cushioned, the back is not. Headrest issues- the metal bracket does not fit so I was not able to attach the much needed headrest. Tried to connect w/support “site not found.” So I will return it

  • Great Chair…but
I returned the chair, because it was perfect except for the seat. The seat was very hard. My wife purchased the T50 a few years ago and it’s a great chair. My understanding was that the T40 was about the same with less controls so I took a chance with it. I would have kept the T40 if the padding was the same or similar to the T50 model. Please replace the T40 seat with something a lot less rigid. ... show more

  • Awesome!
Color: T40 | Black
One of the easiest assembly ever. The makers really took an effort to make sure the customer was not left scratching their head trying to put this together! The Material does feel a bit “plasticky” but very very comfortable!!😀👍
