Paying a product "expensive" is not a guarantee of quality ... The proof is with this "extra bed" bought 69 euros. There still has some good things like surface. Indeed, it is really comfortable for two people (although with the form, the trend is sliding toward the center and finds herself "stuck" to his or her partner! But overall it's very disappointing (for the price again). The mattress deflates and for my part, I have to put the pump on every two nights! A mention also ... the fitted sheet protection! This does not hold. Finally, the mattress is rapidly deformed in width. Therefore prefer a good old mattress "socks" ... Less comfortable but many expensive months, and more robust.
