Really surprised this gets such good reviews. I used mine for 4 months and decided to buy a different chair. The back rest is awkward and you raise it and tighten with a flimsy tension knob which can't hold it up, so the chair back slowly sinks throughout the day meaning I lose back support. The chair cushion is too hard for me and it doesn't feel soft, it feels like sitting on a hard surface after a while. I alternate sitting and standing throughout the 8 hour workday but still this chair is giving me pain.

This is just THE best possible home office chair we have ever had. I bought this after sending back a Habitat chair which was so awful. Bought this due to reading scores of excellent reviews. They were telling the truth. Brilliant back support (have had discectomy so need proper support). It looks brilliant - bought the purple. Glides perfectly on a floor protector mat. It could not be better. We struck gold with this and I recommend it comprehesively. My son loves it and my husband loves it. It is an amazingly reasonable price for such a good chair. Love it.
