They lied
"They sent the wrong mattress. I ordered the twin XL and received a regular standard size mattress. I questioned the $100 pick up fee and was told I wouldn’t be charged. They charged me anyway. Their sales people lied. Period. Now I’m trying to get that money back. I can understand the fee if I just didn’t like the mattress, but they sent the wrong size. They did it and they will not take responsibility for their error."
