FYI - If you need to return the mattress, Casper maintains you bought from Amazon, not them, so you are out of luck as far as they are concerned. Casper will not assist with the return at all, let alone the pick up included in their advertisements. Amazon has you take the mattress to UPS or pay $30 for a pick up. Either way, UPS will not take the mattress without a box. The mattress does not fit back into the box. Amazon is not concerned about how you get it into a box or to UPS. Although the Amazon site reads as the “ Casper Store” and refers to the 100 day guarantee, it is not accurate. Buy straight from Casper if there is any chance you might need to return it. You also may want to pause and consider what appears to be their business practices before purchasing from Casper.
