The chair is comfortable and provides good lumbar support. The backrest arrived with a small 1/2 inch tear in the mesh at the top of the backrest. I noticed it 2.5 weeks after purchase and the return policy is a very short period of 14 days. The armrests are set too wide even when adjusted to inward positions.
This would be a great chair IF THE SEAT cushion lasted but it doesn't. If you buy this chair you will have to buy a NEW ONE EVERY YEAR. Perhaps they like it that way. I've done it twice now. Never again. Spend more now spend less later...
