I bought 2 size medium (for my wife and I to sleep on over xmas) and I have to admit they were very uncomfortable.
Slept on it for 2 nights, I'm 6'1, 93Kg and my wife is 5'1 (so very petit), and we both suffered equal amount of aches and pains next am.
Although they look padded and comfortable sleeping on these (for prolonged period) felt like I was sleeping on the floor, zero padding - I don't know what the last reviewer sleeps on 'best mattress ever slept on, better than own bed' but, in my honest opinion, these are far from "better than my own mattress"
Advertisement is also misleading, it says 'medium size' and the picture suggests spacious enough for a grown adult but my feet and my shoulders were hanging off the edges!
I would suggest this product would be perfect for lounging around the pool, in a park or on your deck but definitely not ideal for a night sleep.
As a positive the fabric and colours are great but sadly not ideal for sleeping or the [...] price tag.
