This mattress is the 1st one I have bought after sleeping on it at a motel. The day I checked out, I flipped the mattress up to read the label. I then went to a furniture store that sold Serta but they told me I could not buy that model from the store. So we bought another Serta model, but after a few weeks took it back - it just did not meet our expectations.
So I contacted the motel, asked them about the mattress and they referred me to the Guest Purchase program at Serta. I entered the name of the hotel, was able to confirm the model I wanted and it was delivered promptly.
Thanks Serta!
