Best Hybrid Mattress

Purple Restore Hybrid Mattress

$3998 at Purple

You may recognize Purple from its playful commercials featuring characters like a Big Foot family or Goldilocks. While the brand leans into humor with its advertising, its mattresses are no joke. In fact, they’re among the most comfortable options available for all types of sleepers.

“I used to have a lot of back pain after a long sleep, but all that pain has disappeared since getting a Purple hybrid mattress,” says Sean Tirman, a content updates editor at Reader’s Digest. “While this mattress was a hefty initial investment, I don’t regret the purchase for even a second. I’ve never slept better in my life.” He mentions that the mattress takes some time to adjust to and is quite heavy, but the combination of Purple’s grid top, foam layer, and supportive coils creates an ideal balance of softness and support.

Sizes available: Twin, twin XL, full, queen, king, California king, split king | Materials: GelFlex grid, comfort foam, coils  | Sleep trial?: 100 nights | Warranty?: 10 years | Firmness: Medium firmness

What to consider when buying a full-size mattress

Before buying a mattress, it’s important to consider a few factors. Here are the biggest ones you should consider:

Sleep style/comfort

Start by determining your preferred sleeping style—whether on your stomach, back, side or a combination. Assess if you experience overheating at night. If you share the bed with a partner, consider if either of you is easily disturbed by the other’s movements. These factors will help you narrow the optimal firmness level and identify desirable features such as cooling materials and motion isolation.

Space/room size

Mary Fenton tells us, “Full mattresses are typically best for single adults, tweens/teens, couples who don’t mind sleeping close together, or people who have limited floor space.” If you don’t need a lot of room (and you’re a single person), you might be better off with a twin. However, if you need a bit more space, you’re probably better served by a queen mattress.

Trial period/return window/warranty

“Most brands offer generous sleep-trial windows, where you can sleep on the bed in your own home for a period of time (typically between 30-265 days) and return it if you’re not satisfied,” says Fenton. These factors can be crucial, as it is difficult to decide whether a mattress is good for you by specs alone—you have to actually try it out. But you don’t absolutely have to shell out the cost first, either. Fenton adds, “To test a bed out in person, do your comparison shopping online first, then visit a brick-and-mortar store near you to lay on it and see how it feels.” 

Price/discounts

With technology progressing the way it has, budget mattresses are better now than ever before. “While a cheap mattress may not be as durable as the more expensive models, they often offer comparable levels of comfort and support,” Fenton says, adding that you’ll have to replace a budget mattress more often. It’s also worth considering waiting for sales to kick in, as brands offer steep discounts around major holidays (like President’s Day). Fenton adds, “Online brands often expand their sale periods, leading to more frequent sales and steeper discounts.” Check out these mattress deals for big savings on the best full-size mattress.

Types of full mattresses

When searching for the best full-size mattress, there are options to suit every sleep preference and budget. Choose from memory foam beds, non-toxic mattresses, organic options and convenient bed-in-a-box models. If you’re short on space or need something simple to store, the best full-size air mattress will easily deflate and neatly stash away until its next use.

FAQ

Is a double mattress the same as a full?

Yes, a full and double mattress both have the same dimensions ( 75 inches long and 54 inches wide). It is the same length as a twin mattress but adds over a foot to the width. Full-size mattresses are available in various thicknesses, usually eight to 14 inches. In the past, mattress manufacturers labeled beds as “single” or “double,” corresponding with the number of people who could sleep on each bed. Most brands no longer use these labels and now offer a larger variety of sizes.

Can two adults sleep on a full mattress?

The best full-size mattress comfortably accommodates two adults, provided they don’t require much space to spread out. Couples who enjoy close cuddling often find a full mattress sufficient. However, if you and your partner prefer ample space or share a bed with pets, a full mattress may feel too small for your needs. Check out these best queen-size beds instead.

A full-size mattress is ideal for single adults or couples who like to sleep close together. These beds are more budget-friendly, so they are popular for teenagers or children in a shared room. They’re also a space-efficient choice for small bedrooms and popular options for guest rooms.

Which mattress is best, spring or foam?

Every mattress type has its pros and cons. Spring mattresses provide excellent support but can sag over time, leading to pressure points and back pain. Foam mattresses offer greater comfort and reduce pressure points but tend to retain heat and are heavy. Hybrids combine the benefits of both but are usually the most expensive option.
