My wife and I are looking into buying a new mattress as well as a new bed. We like one of the platform beds at Ikea, but we're hesitant to buy a new mattress without boxsprings. Our concern is that the mattress may not be as comfortable or may wear out more quickly if we don't use the matching boxsprings or foundation. We're planning to get either a Sealy or Stearns & Foster mattress if that makes any difference. So, what's the verdict, will a mattress be equally as comfortable and durable on a platform bed (or a bed with lots of slats) as it would be on its matching boxsprings?
