Buying a new mattress can be intimidating. It's a big investment in something that is meant to last many years. And you have to sleep on it.
The number of choices available does not make the hunt any easier. Do you want coils? An air mattress perhaps? What about memory foam?
Mattress choice is a personal decision. No one mattress would suit everyone needing a night's sleep. So how do you find the one that's right for you?
Well, you could lie down. Check out that mattress, and don't cut the time short. You'll need 15 minutes or so to be able to tell if you are a match.
Shop later in the day, when any of your regular aches and pains are likely to have shown up.
"If you take care of your mattress, rotating and flipping every six months or according to the manufacturer's instructions (foam and pillow-top mattresses generally just need rotating, no flipping), it should last at least a decade, the experts say."
