This mattress offers a high quality combo of firmness, support but also it’s not stiff, offers just enough softness. Daughter loves this queen mattress. Can see it lasting a long time. The price on Best Buy even at full price is cheaper than getting it at the Molecule website as of this writing by almost 50%. It took less than 24 hours to fully expand and fully fit the bed frame from unpacking the box. That said the box on delivery is very heavy! Great buy!
