Love this mattress! It came so super fast. Set up was so easy. It literally comes in a bag and all we did was unroll it, cut the plastic wrap and boom! Mattress inflates immediately. No need to wait 24-72 hours. The height is exact. 14 inches tall. No movement transfer. My husband can now come to bed late and him getting in bed does NOT wake me up at all! Its soft but not TOO soft and my hip pain has all disappeared. Highly recommend, and of course, if you do not like it, you have 100 nights to try it out and you can exchange it! Wayfair is the best...
