These beds are able to bend and elevate at varying angles. As a result, the mattress has to be flexible. Different types of mattresses can be used on an adjustable bed – memory foam, latex, or air, for example. Spring mattresses are more difficult to use, however, because the springs don't handle the bending well.
Pros: For people who have difficulty getting in and out of bed or who like to watch television in bed, Shamie says, adjustables can make life easier by moving you closer to where you need to be.
Conditions: If you suffer from sleep apnea, sleeping flat can make the condition worse by cutting off airways and causing the tongue to fall into the back of the throat, Shamie says. People who experience acid reflux can also benefit by sleeping in a bed that elevates their upper body.
Shamie also suggests adjustable beds for people with hip or back pain who have a hard time moving from a lying position to sitting up or standing.
When you have guests staying for a night or two, sofa beds come in handy. The mattresses in these beds tend to be very thin so they are flexible enough to fold and collapse into the couch. It's a great convenience to have a sofa bed, but you'd be hard-pressed to find someone who raves about their comfort.
Pros: Sofa beds are convenient, especially if you have limited space. But from a health perspective, Shamie and Breus don't see any advantages.
Cons: A night or two on a sofa bed is OK. But "this is probably the worst kind of bed you can sleep on long-term," Shamie says. The mattresses used in most sofa beds are very thin and the springs quite weak. "It really leads to an uncomfortable situation," Shamie says.
If you're really tight for space and need a bed that folds up, Shamie says that futons, while not the most supportive, are better for your back than the typical sofa bed.
Conditions: There are no conditions for which a sofa bed will be helpful, according to the experts. But if you have a bad back or hips, these beds will be especially uncomfortable.
