I ordered the Ergo Prosmart adjustable base as 2 twin xl mattresses to make a split adjustable king. I got the floor model from a Mattress Firm location and was assured even though it was the floor model, it was still covered under the TempurPedic warranty. One of the massage functions at the head of the bed hasn't worked since it was delivered so Mattress Firm told me to start a warranty claim to get it fixed. I did that and the claim was denied saying floor models weren't covered under warranty. I'm not sure if Mattress Firm or TempurPedic is to be mad at, but now I have a defective product that's a month old and no way to return it or get it fixed without having to pay out of pocket. For the price I paid (even for the floor model) I expected more. Very disappointing.
