very basic foundation for your mattress - quality is not great - the top layer of the foundation is some kind of cardboard material which is not sustainable for what I would consider a long term purchase - I learned that this was the material upon arrival but did not think anything of it at the time - now I regret not returning this item as it is no longer as supportive as it was when it arrived - I contacted Wayfair and the manufacturer will not stand by its product, however, Wayfair offered a partial refund which was okay, but now I'm stuck with this subpar product - my recommendation is to buy a Casper foundation which contains wood slats which are necessary for the product to function as it should over the long term or any kind with wood slats
