I was tired of low quality mattresses with low density foam that are growing and sag so I was looking for a mattress with a foam of at least 30kg / m3. I bought this mattress on Amazon for this density because it is almost 2 times less than in the traditional trade ... However we must see to use (1 or 2 years); I will give update this comment if it loses its strength. My usage: a child of about 40kg Goodies: received quickly, well packaged, consistent with the description. it is firm enough and comfortable enough. Cons: unpleasant odor at the opening but which dissipates rather quickly, and a coating (admittedly removable) 100% synthetic not very pleasant to the touch.
edition of 06.29.2014: as promised I have to update my review after 6 months of use: the mattress has not moved, it is still as firm and comfortable. So I added a star ... but big downside, it rose from 54 to 87 in six months! it must be the price of success ... it's still a good value compared to competition, but admit that the law of supply and demand is ruthless at the time of internet!
