Mattress Warehouse / SleepHappens.com review: defective mattress

purchased a mattress on feb.15, 2010 along with a mattress cover, not even a year later the mattress has a dip in it and my kids spilled juice which is now on the mattress and now any warranty is voided by this.mattress cover was soppose to guarantee any soilage, the cover alone cost 90 bucks mattress warehouse is a ripoff now i know what to look for in a mattress next stay far away from themIlsao purchased a platform bed which broke a month later because it wasnt put together fully some parts were left out
