I loved that these chairs came so fast - within 3-4 days & in a way that was very easy to put together. I think it took no longer than 5-10 minutes to put each chair together. Everything fit into place & I was immediately able to sit down in them & enjoy! The only negative I would have with the chairs is that you can’t put the legs up without leaning back in “relax” mode. The other small issue is that the massage vibration will not let you just do the lumbar area. It keeps moving from head to lumbar to feet no matter what mode you choose. I had hoped to have a chair to mainly put heat & vibration on my lumbar area. But otherwise I think it is a great chair! I definitely would recommend them!
