On the product description it is described as "medium-firm" - it's actually extremely soft, if you sleep too close to the edge you feel like you're gonna roll off. Also, it's advertised as "deep" but again, not really. The thickness on the information section says 19cm, but the one that arrived is no more than 16cm thick - even after it was left without being slept on to puff up for an entire week (it is delivered vaccuum packed)
