A Few Things to Keep in Mind

Firmness: The firmness of a mattress is a subjective matter, but most mattresses fall within three general categories: soft, medium, and firm. It is usually dependent on your preferred sleeping position, with side and back sleepers often looking for a softer mattress, and stomach sleepers seeking a firmer option, says family practice physician Peter Bailey. Looking to relieve back pain? “Medium-level firmness tends to be good for pressure and tension relief for people with lower back pain,” says Alex Savy, a certified sleep science coach and the founder of SleepingOcean.com.

Quality: Think of a mattress like a sandwich composed of many different components. Quality mattresses will not only be constructed of high-density foam that provides the structure you need, but will be layered in a way that optimizes both comfort and support. This usually means a heavier, denser foam (or coils) on the bottom, and lighter, softer foam on top that gives in to your body weight.

Packaging and delivery: Most foam and hybrid mattresses that are ordered online arrive in a box for easy shipping and delivery. After its taken out of the box, the mattress can typically be released from its vacuum-sealed bag and unrolled, after which it might take a few days to fully inflate and reach its final depth. One note to keep in mind: Just because its in a box doesnt mean its easy for one person to pick up and maneuver!

With a durable base bottom for long-lasting support and a responsive, soft foam top, Caspers Element mattress is soft—but not too soft—regardless of your sleep position.

Supportive yet soft, this memory foam mattress is designed to conform to your body’s shape. At the core of this mattress is a 6.5-inch base foam that provides deep support, followed by subsequent layers of transition and memory foam. The top layer is a 1.5-inch firm support foam that isolates movement, keeping your partners tossing and turning confined to their side of the bed. While the mattress is available in four profiles (6, 8, 10, and 12 inches deep), the 12-inch mattress offers the most durability and support at a great price point.

It’s great for people whose sleep position might change over time due to medical reasons, and, as Robert Pagano, cofounder of Sleepline, points out, “The gel foam does a great job of conforming to your body shape.”

Best Memory Foam: IKEA Matrand Memory Foam Mattress

The Best Affordable Mattresses Option: IKEA Matrand Memory Foam
Matrand Memory Foam, Ikea ($349)

IKEA mattresses may have gotten a bad rap over the years, but that doesn’t mean they’re all back-pain inducing. In fact, Samantha Weiss-Hills, our commerce deputy editor here at Domino, strongly recommends this memory foam one. “It’s not plushy soft by any means, but the memory foam is pretty good for people who like a medium-firm mattress,” she says. “It gives in as you rest into it, like memory foam should.”

Best Hybrid: Allswell Home The Allswell Mattress

The Best Affordable Mattresses Option: Allswell from Allswell Home
Mattress, Allswell ($375)

Hybrid mattresses combine the firm support of traditional coil or spring mattresses with the plushness and comfort of memory foam mattresses, and tend to be on the pricier side.

The top of the mattress is quilted for a bouncy, sink-into-the-bed feel.

As the name implies, the Breeze mattress from Sweetnight is designed for maximum cooling for hot sleepers.

Best for Couples: Sweetnight Twilight Hybrid Mattress

The Best Affordable Mattresses Option: Sweetnight Twilight Hybrid Mattress
Twilight Hybrid Mattress, Sweetnight ($498)
Shop
As a hybrid mattress, the Twilight from Sweetnight was specifically designed to provide excellent motion isolation with individually wrapped coils that give that traditional bouncy feel—without the motion transfer across the whole mattress. If youre a light sleeper or have a partner who tosses and turns in their sleep, the combination of coils and foam will keep your partners nightly workout confined to their side of the bed.

Pro Tips for Buying an Affordable Mattress

  • Some foam or hybrid mattresses can be thicker than traditional mattresses at 12 to 20 inches high (standard mattresses clock in at 8 to 12 inches). This means that the fitted sheets you already have may not fit anymore, so make sure you check before you purchase—otherwise you may find yourself needing to buy brand-new sheets along with that brand-new mattress (which, come to think about it, doesnt sound so bad!).
  • Finding yourself sliding off when you sit at the edge of your mattress? Poor edge support—where the outer edges and corners of the mattress are soft and flexible—is likely the culprit. Look for a mattress on the firmer side—and youll end up making the most of your mattress’s surface area, to boot.
  • There are times in life when its possible to have two things at the same time, and hybrid mattresses provide one of those moments. Thanks to their combination of structure and softness, they often offer the best support and overall feel, says Bailey, and comfortably accommodate a range of sleeping positions.

Q: How can I tell if my mattress is causing my back pain?

“One sign that your current mattress might be causing your back pain is if you wake up sore with backaches in the morning but not when you wake up after taking a nap,” says Pagano. The right mattress will be supportive enough to help your spine maintain a neutral position—preventing that pesky back pain and soreness.

Q: How will I know when my mattress needs replacing?

Experts generally recommend replacing a mattress every five to eight years, depending on the frequency of its use, how often you move and change position during sleep, and your weight. If you feel muscle stiffness in the morning, it’s a good sign that you should replace your mattress, says Savy. “Usually, this indicates that the mattress has degraded and is unable to offer spine support,” he explains. Adds Pagano, “If you don’t feel refreshed upon waking or anytime during the day, it’s likely that a fresh mattress would help.”

The Last Word

A good mattress is the key to good sleep, and it can be tempting to feel like you need to spend a fortune in order to find the right mattress for you. But the reality is that not everyone has the same needs when it comes to a mattress, and sleeping position and personal preference play an important role in what feels best. The best affordable mattresses that weve selected consider not just the type of sleeper you are, but also the types of material and mattress construction that should be considered so that you can sleep well—without worrying about overspending.
