Won't be able to properly review until we take it to our condo in Myrtle Beach in April and unwrap it to see how it expands. Update: just now got it to our condo and slept on it. I hate it. It is not any better to sleep on than the spring mattress that came with the couch originally. You can still feel the bar through it and I had such high hopes for the price that this would be a great improvement. It is not and it is shorter on the sides making it really hard to get out of the bed because of the side metal frame from the bed cutting into your legs when you get out. I would not recommend this at all!
