Excellent choice for people under 5'5"
This chair is the perfect size for people under 5'5". The ability to swivel the armrests allows for support while using a keyboard. The lumbar support provides a range of depth preferences. Easy to clean.
Verified Purchase
Nice change from previous padded high back chair
This is a very comfortable chair with all the adjustments to create a personal fit. It appears that the mesh should wear well but time will tell. The chair is very solid and the fit and finish is as good as can be expected.
