We bought this to replace the original mattress in our RV. The old mattress would cause back pain after 2 nights. The Ghost Bed is awesome no back pain even after a week of nights in the rv. Delivery great quality seems top notch. I would give this 5 stars expect for two very minor issues. Number 1 the mattress is much thicker than the old one so getting in is a little more of a challenge. Second it is very firm made a little to firm for my wife but nice for me. Now after many trips the mattress is breaking in and it seems more comfortable after every sleep. Would recommend and would buy again
