These chairs are excellent. They are comfortable, supportive and slide well. There is even a lock on the slide to prevent the chair from sitting up or sliding back unintentionally. The table on the side is an added bonus. I am so glad we found these chairs and bought them.
Great seats. Setup was a big complicated as I was sure how to put on the shelves, but I figured it out. Manual does not come with it. Very comfortable. Locking mechanism isn't very reliable though.
Came without cupholders, started minor cracking on 2nd use. (My husband and I are both under 175lbs, so not very large people....no reason this should happen)
