It started hurting after a month. The lumbar was good but the seat cushion is split into 2 halves. Right in the middle where the 2 halves meet there is a seam that sticks up higher than the rest of the cushion and presses on my butt and thigh. After a few minutes it starts to hurt. I bought a fusion for it but it doesn't help at all. I wish It would have started hurting during my trial period but after a couple of months it started hurting at that seam. I've had many chairs from Staples and never had a problem but this one is horrible. My favorite one the memory foam chair finally broke after 10 years. That was a great chair and the Rutherford is really bad. The picture shows where the problem is and where it is harder than the other part of the cushion.
