Getting a great night's sleep depends on oodles of factors from external elements such as bedroom temperature to internal stuff like your stress level. That said, an essential ingredient in catching some quality Z's is a comfortable mattress.
For the ultimate in body-hugging comfort, you can't go wrong with a memory foam mattress. Compared to traditional ones, memory foam options offer superior pressure relief for aching backs, shoulders, and hips. If you're up all night because of your partner’s tossing and turning, a memory foam mattress will dramatically slash motion transfer. Suffer from allergies? Memory foam mattresses are relatively dust mite-resistant.
Here, the best memory foam mattresses on the market.

"In our experience, back sleepers found it more comfortable than stomach or side sleepers—the latter who generally need softer support around the curve of their hips and shoulders. However, our lone stomach sleeper thought it did prevent their back from bowing, which often happens with memory foam mattresses."—Stacey L. Nash, Product Tester

What to Look for in a Memory Foam Mattress
Type of Foam
“Traditional” memory foam is made up of polyurethane-based viscoelastic foam, but there are a few other types of foam used as well. Plant-based memory foam has become a popular choice for its improved breathability and more eco-friendly manufacturing. Also, some foams are infused with gel or copper to make them cooler to sleep on.
The density of memory foam, measured in pounds per cubic foot, tells you how well the mattress will support you, retain its shape over time, and reduce motion transfer. High-density foam (6 pounds per cubic foot or more) is the most supportive, firm, and durable. If you want a plush mattress, opt for low-density foam (3 pounds per cubic foot or less), but keep in mind it will be less supportive.
If you’re a hot sleeper, you may find a traditional memory foam mattress retains too much heat—look for a mattress with open-cell construction and gel or copper-infused foam to help you sleep comfortably.
How long do memory foam mattresses last?
Memory foam mattresses can last anywhere between 7-10 years, with 7 years being average. There are a few factors that play into this: cleanliness, rotation (or lack thereof), allergy issues, pets and children, etc.
How do you clean memory foam mattresses?
You can clean a memory foam mattress in several ways: vacuuming (best for surface level debris or dust), a cleaning solution (diluted fabric cleaner, dishwashing soap, or a mild detergent work best), or spot cleaning. However you clean, be sure the mattress is completely dry before using or covering with sheets.
How long do memory foam mattresses need to expand?
As soon as you receive your mattress, it's recommended to open it right away to start the expansion process. It typically takes anywhere between 4-6 hours for the memory foam to expand 90% (and potentially another 4-6 hours for full expansion). Experts recommend waiting at least 24 hours before laying on it.
