Check Paypal for offers $ off Mattress Firm. I had $80 off $400. Also use discover via Paypal for another 5% off, and 7% cashback from G*iving Ass*stant

The KINGS25 code worked on the Serta Perfect Sleeper Elkins II 11" Plush Euro Top Queen Mattress. Subtotal went from $699.99 retail, to $349.99 sale to $262.49 with code. Add tax and free delivery and it felt pretty slick. They don't remove old mattress without the $99 upgraded delivery/set up option. I guess you can't win them all, thanks for the find!

Do the firm and extra firm need a box spring? I have a platform bed with slats and am looking for something firm that doesn't require a box spring.

Kick myself for buying a split-king (2 twin xls). Never find good deals on replacements. And the cheap sheet sets only fit twin beds.

this guy named calvin said you can cancel up until delivery and there is no restocking fee due to nothing to restock.
