I'm using it right now as I write this review and since I'm working from home, use it for hours at a time. However, I also purchased a high-low desk so I can stand intermittently as well. Comfortable and is easy to sit on for long periods of time.
Super easy to put together- only 6 parts! And it's super fun/comfortable to use. Built in flex make it easy to reach for things, and the rocking capability is really nice. I don't feel like I'm fighting my body to sit up straight all day. It's AMAZING!!!
Good quality product, has been a great help with my posture especially during work from home time. I particularly like the design compared to other products available, which makes it worth the higher price
Excellent quality and excellent customer service. I was able to order a matching backrest for this chair direct from seller. This chair has helped with my lower back pain while sitting. I'm considering buying one for work as well.
The chair is good quality! It was easy to assemble even without any instructions. I had a knee replacement 18 mos ago. I get shin splints and you wouldn't believe how you just want to stretch out the front of your legs and just can't. This chair gave a nice stretch. No pain.
It is costly, but also very comfortable for long days at the office. Varying between this and standing have resolved my back problems from long days at the desk.
Comfortable for my knees as it’s actually my shins that are used. Much better for my lower back but I did notice pain in my tailbone if I sit too long. It may simply be a matter of adjusting to different muscles and sitting further back on the seat.
I am still getting use to the position and can't sit on it for long periods of time. but it helps my posture and feels very natural. Very easy to put together and high quality. Worth the price for sure!
