When my husband and I got married and moved into our in-laws' house, we just used the existing bed in his bedroom. But I can't sleep very well because the mattress is sturdy foam and I would get backaches and headaches and neckaches the following day.
Finally we went shopping for a mattress because we have an existing bed frame. We found the Dewfoam queen sized matress that was a combination of good quality foam andheavy duty spring. It is stable, so we don't bounce on the bed whenever we move. Yet it is soft enough not to give me backaches.
I think this is one good mattress for me. Since then I have had wonderful nights in bed and no more backaches and headaches the day after.
For its price, we got a really good buy.
