Purchased a queen size Sealy Humbolt Mattress that was sold as a Firm, after 3 nights sleeping on it, It became a hammock shape and had to climb uphill to get out of bed and cause back pain. Penny's makes it very difficult to return. Never will recommend Sealy or Penny's again. Very disappointed at JC Penney's and Sealy for selling Junk like this mattress.
