Twin XL size mattresses

While there is no one best mattress for everyone, there is a mattress that’s right for you. The best mattresses alleviate pressure, provide firm support, and contain durable materials. Your preferred firmness and budget will determine what your perfect mattress is.

There are four mattress types you can consider.

Memory Foam Mattresses

Memory foam provides excellent pressure relief with its hug-like feel. To create memory foam, manufacturers take polyurethane foam and add chemicals to make it more responsive to heat and weight.

Every memory foam mattress contains two to four layers of foam. The top layer is memory foam, and the base layer is a rigid, supportive foam. Softer mattresses have in-between layers to prevent you from feeling the support core and to make the bed more responsive, despite a thicker comfort layer.

Memory foam’s density can retain heat, which is why many manufacturers infuse memory foam with cooling gels, copper, graphite, or ceramic beads. To prevent heat retention, we replace some of the petrochemicals used in traditional memory foam production with plant-based alternatives. The substitution creates our more breathable Bio-Pur® foam.

Latex Mattresses

Latex mattresses have a similar feel to memory foam, conforming to your body to relieve pressure. Natural latex is an eco-friendly material, as producers harvest sap from rubber trees.

There are two types of natural latex, Dunlop and Talalay. Dunlop is a firmer material, as manufacturers add polyurethane fillers to Talalay latex to make it softer. Because of the added steps and material to make it, Talalay latex tends to cost more than Dunlop.

If you have a latex allergy, there’s also synthetic latex. Synthetic latex has a much shorter expected lifespan than natural latex, but the material is also less costly to produce.

Innerspring Mattresses

Innerspring mattresses remain a common mattress choice. Their coil support cores are bouncy and breathable, but you might feel the coils even through a pillow top mattress. The thin comfort layer often cannot provide sufficient pressure relief—and if too thin, allergens and pests may penetrate the mattress and accumulate in the bed’s coil layer.

Partners sharing an innerspring may find that the coils transfer their movements, so a restless sleeper may disturb their partner’s sleep.

Hybrid Mattresses

Hybrids mattresses mix innerspring coils with 2 to 3 inches of foam. Typically the coils are individually wrapped, known as pocketed or Marshall coils, to prevent motion transfer. The foam layer is thicker than an innerspring’s thin padding, providing more pressure relief and preventing allergens from penetrating the mattress.

Yes. This is the idea behind a split king size mattress, where manufacturers divide a mattress into two twin XL size halves. With a split king mattress, couples can personalize each side of the bed to their firmness preferences.

Prices for our twin XL mattresses vary, starting at $749 for our firmest model, the AS1.

While queen and king size mattresses have many variations such as an Olympic queen or a California king, there are only two types of twin mattresses: a regular twin and a twin XL. A twin size mattress works well in guest rooms and children’s rooms—but the 5 extra inches of a twin XL size mattress can accommodate taller people.

You should choose a mattress firmness based on your preferred sleeping position and weight. For example, side sleepers need a plusher mattress than back and stomach sleepers.

Sleeping Positions

• Side sleepers need a soft to medium mattress to ease pressure in the shoulders and hips while meeting their bodies’ curves for support.
• Back sleepers need a medium-firm to firm mattress for back support and pressure relief for the hips.
• Stomach sleepers require a medium-firm to firm mattress to support neutral spine alignment.
• Combination sleepers need a medium to medium-firm mattress to maintain alignment.

Body Types

• Petite sleepers under 130 pounds need a softer mattress to conform to the body for pressure relief.
• Average sleepers between 130 to 230 pounds require a medium surface for a mix of support and comfort.
• Heavy sleepers over 230 pounds need a firmer mattress to take on their weight with premature sagging.

Our mattresses come in five different firmnesses:

• AS1—Firm
• AS2—Medium-firm
• AS3—Medium
• AS4—Medium-soft
• AS5—Soft

Mattresses can feel different over time because materials soften as they wear out or grow firmer as your body compresses the comfort layer through frequent use. If you need to change the feel of your bed, consider adding a foam topper.

The Amerisleep sleep trial lasts 100 nights, with the first 30 nights being a required adjustment period. If the customer doesn’t like the mattress after day 31, then Amerisleep can work with the customer to pick up and return the used mattress before providing a full refund.

Amerisleep offers a 20-year warranty, one of the best in the industry, covering sagging greater than 1.5” inches and defects which could damage the bed. Most mattress companies only cover sagging greater than 2 inches.

Our mattresses are built to last 10 or more years. Our mattresses’ durability is why we include a 20-year warranty that covers sagging greater than 0.75 inches.

Yes. Our AS2’s medium-firm feel is excellent for alleviating back pain. The medium-firm feel maintains neutral spine alignment.

Like all memory foam mattresses, it’s best to keep an Amerisleep mattress on a foundation with consistent, even support. We recommend solid or slatted platform bases—preferably slatted, as air can then flow through the mattress and wick away heat and moisture.

Adjustable bases are also an excellent place to put your mattress, particularly if you have a health condition such as restless legs, snoring, sleep apnea, or acid reflux. Adjustable bed frames raise parts of the body for better blood flow and unobstructed airways. Many adjustable foundations also include extra features such as massagers, under bed lighting, and USB ports.

We strongly advise against keeping your Amerisleep mattress on a box spring, as the coils inside a box spring are not grouped closely enough to offer the consistent support a memory foam mattress needs. If you keep a memory foam mattress on a box spring, parts of the mattress may dip between the box spring’s coils, stretching the bed and negating its support. This is why keeping your Amerisleep mattress on a box spring voids its warranty.
