Lie down on each model for several minutes and turn from side to side to check comfort and support in all positions. Take your partner and try out the models together - both should make the decision. Ask questions and look for several key attributes. Make sure the mattress is an innerspring and at least nine inches thick. Sit on the edge and check for support and return to original shape.
Research indicates that only innerspring mattresses and foundations provide the proper support.
Think about size, think modern. The old-fashioned double bed provides only 26 inches of sleep space for each person. That's about the same amount of space as a baby crib. Today's modern Queen or King mattresses will fit just about any bedroom. The bigger, the better.
