It may be correct! Mine is rated at 860# and it is actually 990# on a CAT scale. Sometimes companies though can be tough regarding sales. You might try recording the transaction repeating the policy in the future.
P.S. Be careful posting about companies. I have a story regarding a recorded purchase. Five times in the recording I say that I want a rectangular mattress cover saying it over and over for my radial mattress Airstream!?!
Even the sales person mentioned the previous radial twin mattress I ordered and I say no
. I posted on the forum and they came after me. I plan on making my own recordings when ordering things like that in the future.
