Always a bit apprehensive when ordering anything online. We had just bought a new sleep bed & needed a memory foam. After looking at all that was available on OS, it was hard to choose from. So I started reading the reviews & this Grande Hotel Collection had great comments & information. So based on the comments we went with this one & very glad we did. We loved it from the first night we used it. We have a king bed & the size measured up perfectly, and the thickness of the foam was perfect. For all those that read reviews (like us) we defiantly would recommend this memory foam.
