My Simmons Beautyrest World Class Starvo X-Firm mattress sold to me by Mattress Warehouse on 1/28/09.  BE WARE BECAUSE MATTRESS WAREHOUSE WILL NOT DO A COMFORT EXCHANGE OR REFUND MONEY EVEN IF MATTRESS HAS NOT BEEN DELIVERED. Mattress is so hard that after my first nights sleep I woke up with bilateral hip pain.  This occured again after second nights sleep. Simmons and Mattress Warehouse don't care about the little guy....just about taking the little guys money....Nothing more then a bunch of big bullys.  BUYERS BE WARE OF SIMMONS AND MATTRESS WAREHOUSE. Now out $1400.00 and can barely walk...
