The whole process was amazing and simple 
its taken me a few weeks to decide on a mattress I did not want to spend mega bucks on a new one, so this being 50% off was ideal, its comfy, does not make any noises nor does it have any odour.. 
best of all first time ordering from WAYFAIR ordered 3pm on a friday afternoon it arrived 18hrs later at 8:55 on the saturday morning ! you could not ask for a better more efficient delivery !
