Our Affinity transition foam with HIVE® technology provides incomparable pressure relief and support. The HIVE® technology has five support zones to distribute your body weight.

The most popular hybrid mattress we offer at Amerisleep is the AS3 Hybrid. Its balance of support and cushioning is a good choice for petite combo sleepers. With the pocketed coils, the mattress stays cooler and prevents sweat, uncomfortable nights.

The AS3 Hybrid is 12 inches thick and contains 3 inches of Bio-Pur®, 8 inches of pocketed coils, and 1-inch of base foam. Unlike the memory foam AS3, the AS3 Hybrid does not contain Affinity foam to ensure it feels balanced.

The coils are wrapped in lightweight fabric to increase durability and prevent squeaks. This way, there’s less chance of the coils break, motion transfer, and feeling unsupported. Also, we use firmer coils on either side of the mattress, ensuring the bed has reliable edge support.

Mattress Types for Petite Sleepers

As a petite person, you have the same mattress options as most other people. When choosing a type of mattress, consider your budget, how you want your bed to feel, and how long you want your bed to last.

Memory Foam

Memory foam mattresses are the right choice for smaller people in need of excellent pressure relief. A memory foam bed will hug your curves to prevent pressure build-up and ensure you sleep comfortably.

Common complaints with memory foam are how it traps heat and can cause you to feel “stuck” in bed. You can avoid these issues by getting plant-based or infused memory foam mattresses. For instance, gel-infused memory foam dissipates body heat well and is responsive, so you can move easily in bed.

Most memory foam mattresses aren’t made entirely of layers of memory foam. Instead, the top layers of foam are memory foam, while the bottom layers are often durable poly-foam.


Latex mattresses are known for being cooling, buoyant, and sustainable. Latex foam isn’t quite as pressure-relieving as memory foam. While it still cushions your body, it does a better job of distributing your body weight and keeping you lifted.

Natural latex comes from the sap of rubber trees, which is then whipped into a foam. This makes it a good eco-friendly mattress for people looking to reduce their carbon footprint.

Plus, the one of the benefits of latex mattresses is how utterly durable they are. Latex beds last 12 to 15 years on average. so while they’re a bit expensive due to the natural materials, you can use them for longer.


Innerspring mattresses are a popular choice when you’re on a budget. They’re known for their excellent support, breathability, and signature bounce.

Innerspring beds contain continuous coils, meaning there’s one piece of wire making up all the springs. They feature pillow-top comfort layers, which are typically made from cotton, feathers, down, or polyester.

While innerspring beds are readily available and cheap, they’re not the most reliable beds. The springs can squeak, break, and cause motion transfer. Also, the pillow tops don’t offer the same pressure relief as memory foam or latex mattresses.


Hybrid mattresses are a great luxury option if you sleep hot or enjoy a bouncy bed. Hybrid beds contain coils—like innerspring beds—and have foam comfort layers—like latex or memory foam beds.

Innerspring beds contain continuous or open coils, whereas hybrid mattresses feature pocketed coils. These are individual coils wrapped in thin fabric to maximize support and minimize motion transfer, squeaks, and breakage.

The advantage of a hybrid bed over an innerspring is the better support, thick cushioning, and good motion isolation. However, hybrid mattresses are much pricier than innerspring mattresses despite still lasting roughly 7 years at most.

Mattress Firmnesses for Petite Sleepers

As a petite person, the most important factor to consider is your firmness level. Most mattress firmness suggestions are based on average-sized people who weigh between 130 and 230 pounds. Petite people should choose softer mattresses in the range of what’s suggested for their body types to make up for the reduced pressure.

Side Sleepers

Side sleeping is arguably the healthiest position you can sleep in. It protects your back, relieves obstructive sleep apnea, Verified Source Medline Plus Online resource offered by the National Library of Medicine and part of the National Institutes of Health.

However, you need one of the best mattresses for side sleeping to reap all these benefits. Otherwise, you might wake up sore and stiff.

It’s important to use a soft mattress (3) or medium-soft mattress (4) when side sleeping to properly cushion your shoulders and hips. An overly firm mattress will only lead to pressure build-up and cause your arms and legs to potentially feel numb.

As a side note, people seeking a mattress for pregnancy often find they’re most comfortable with one suitable for side sleeping. This is especially true for petite individuals who are pregnant and need a pressure-relieving surface.

Back Sleepers

Back sleeping is one of the other most optimal sleeping positions next to side sleeping. It’s easy on your spine, gentle on your skin, and doesn’t suppress your airways. Therefore, the best mattresses for back sleeping help a person make the most of these benefits.

When back sleeping, petite people should use a medium-soft (4) or medium mattress (5). This way, your spine stays neutral without causing pressure build-up around your lower back.

Stomach Sleepers

Stomach sleeping is easily the worst sleeping position for your body. Stomach sleeping causes lower back pain, makes it difficult to breathe, and can cause wrinkles and acne. Still, it’s not always easy to change your primary sleeping position, so many shoppers may want to find the best mattress for stomach sleeping.

If you prefer stomach sleeping, we suggest using a medium-firm mattress (7) to give enough support for your spine. Too soft of a mattress can cause your hips to sink and hurt your back.

Combination Sleepers

Petite people who switch between any of these positions at night usually prefer a mattress with a medium firmness (5). A medium mattress is soft enough to cushion your hips when side sleeping, but also firm enough for back or stomach sleeping.

We also suggest responsive surfaces when shopping for a mattress for combination sleepers. Buoyant materials help the mattress adapt quickly to your movements.


What’s the best memory foam mattress for petite sleepers?

Memory foam mattresses are known for their pressure-relieving properties and hug-like feel. They’re perfect if you deal with chronic pain or simply want soothing comfort when you sleep.

The best memory foam mattresses for petite sleepers are the Amerisleep AS4, Amerisleep AS3, and Amerisleep AS5.

What’s the best hybrid mattress for petite sleepers?

Hybrid mattresses are great for petite people looking for an extra bounce or more breathability. Also, hybrid mattresses come in all types of firmness levels to suit whatever position you sleep in.

Several of the best hybrid mattresses for petite sleepers include the Amerisleep AS3 Hybrid, Amerisleep AS5 Hybrid, and Amerisleep Organica.

What is a petite sleeper versus a plus-sized sleeper?

Petite sleepers are people who weigh less than 130 pounds regardless of their age or height. Conversely, plus-sized sleepers are people who weigh over 230 pounds. The main consideration when mattress shopping as a petite or plus-sized person is ensuring you choose the right mattress firmness for your size.

Should heavy people get soft or firm mattresses?

Just like with petite and average-sized people, heavier sleepers who weigh over 230 pounds should choose a mattress based on their sleeping position and personal preferences. The main difference is that mattresses for heavy people generally need a firmer feel to ensure spine alignment.

For instance, an average-sized side sleeper should use a soft (3) to medium (5) mattress, whereas a plus-sized side sleeper would need something slightly firmer. A plus-sized side sleeper generally does well on a mattress with a medium (5) or medium-firm feel (7).

Do mattresses have a weight limit?

Yes, most mattresses have a weight limit of around 500 pounds, which is definitely enough to accommodate most people. If anything, plus-sized people who share a bed may want to consider looking for heavy-duty mattresses. A new mattress won’t just snap in half if you exceed the weight capacity. Instead, it’ll wear down and need to be replaced faster than normal.


As a petite person, you have many mattress options. You need a firmness to properly cushion your lighter body and ensure you don’t deal with pain or pressure points. With our guide here at Amerisleep, you can compare different soft mattresses and decide what’ll work best for you.
