Pay attention to your mattress. Your mattress can contribute to better sleep. Since the features of good bedding are personal, choose what feels most comfortable to you. Here are some tips when shopping for a new mattress:
If you share a bed, make sure you purchase a large enough mattress so there’s plenty of room for two
Talk to your doctor. If you have a health condition, talk to your doctor about what he or she recommends. Although doctors are not sleep experts, they DO know about your medical condition and will have some good advice.
Pillow tops aren't for everyone. Lightweight people don't need big thick pillow top mattresses because they don't weigh enough to compress the foam to even touch the underlying coils/support system. On the other hand, heavier people tend to feel more comfortable with a little extra cushion between them and the coils.
Test the mattress before you buy it. Before you commit to a mattress, try to lie on the mattress in the store for at least 10 minutes. Don’t worry what other people may thing and don’t let f the salesperson rush you along. It's a big investment, and it’s something you may have for many years to come so make sure you get a real feel for the mattress.
Check the warranty. A good mattress will have a minimum of a 10-year full replacement or non-prorated warranty.
Protect your investment. Invest in some type of waterproof mattress protector. Stains will most likely void your warranty.
