The Classic Euro Top model is quickly becoming one of our best sellers. It is what we consider a “hybrid” mattress combining standard bedding components with specialty foams. For individuals that don’t want an all foam mattress but want the benefits of gel infused memory foam this is a great choice. The high end spring unit used for support coupled with 2” of gel infused memory foam in the euro top makes this mattress great on support and comfort. This mattress is constructed to be one-sided.
