I like it a lot I'm 90 years old and have bone to bone on knees and really helps me to get up from my chair I also like the heating for my back for sciatic . my  son and granddaughter put it together in 10 minutes after reading instructions. I can also take naps in it. It stretches far enough for me to sleep in it .it does not lay flat but I have acid reflux so I can't lay flat.I'm am very pleased with it
