This improves your circulation and keeps your airways open for smoother breathing. We have scoured the internet for the best firm mattresses, so you can make this important switch and start waking up refreshed.

Why we like it:

  • Great lumbar support
  • Several comfortable foam layers
  • Compatible with platforms and slats
  • A cool sleeping experience
  • Firm coil support

With its 120-day trial period and high-quality materials, it’s easy to see why the Aurora mattress is so popular. If you tend to wake up sweating and also need extra back support, this cooling and firm mattress will be right up your alley. Compressed into a 19x19x45-inch box, the Brooklyn Aurora Luxury Mattress is shipped straight to your front door.

You Might Want To Pick The Aurora Mattress If:

  • You’re craving pressure relief: The Aurora mattress has a 4.5-inch top layer made up of medium-firm and medium TitanFlex foam, plus memory foam. The top layer allows your body to sink slightly, so the foam contours around your back and shoulders. The second layer is in place to provide firmness and support.
  • You need more airflow: This mattress is designed with the purpose of keeping you cool. The circular knit cover keeps the material from storing heat. There’s a mix of coils and foam to help with airflow. And the 1.5-inch top layer is also engineered to prevent sweating.
  • You aren’t on a strict budget: Aurora is made with incredible craftsmanship and top-notch materials, so it isn’t the cheapest mattress out there. It could be a good choice for you if you don’t mind spending a lot on your mattress.
  • You’re a back or stomach sleeper: This could be a good choice if you enjoy a flat, smooth-feeling sleeping surface and also tend to sleep on your back or stomach. The TitanFlex foam in the Aurora is responsive and doesn’t allow you to sink too deeply into the bed.
  • You prefer latex materials to soft foam: TitanFlex foam is an alternative to latex. This gives the sensation of sleeping on top of the bed instead of “in” it. There’s also a layer of springs inside for isolating motion.

The Aurora Luxury Mattress is our top choice for hot sleepers because it was made with airflow in mind. The foam used in its construction is Certi-Pur US certified. Let’s look a little further into the materials used in this product.

The cover of the Aurora mattress is made with a two-way circular knit material, which makes it feel cool on the skin. The top layer has TitaniumGel for cooling and copper, making it antimicrobial. The second layer is 2-inches thick for medium-firm comfort, supporting your back and hips.

Next, there’s a 1-inch layer of 2.5-pound density memory foam, providing compression support. This is an important feature for people who sleep heavily.

The mattress is designed to prevent sleep disturbance with its 1,283 Quantum Edge coils. These isolate motion, meaning you won’t wake your partner up if you get up in the night. While you will sink into the mattress surface slightly, the firm second layer keeps you from sinking too deeply into it.

This mattress is built to last with durable fabrics, safety stitching, and Kevlar thread. Brooklyn Bedding uses water-based, non-toxic adhesives that don’t harm the environment. And, they make their own zipper covers instead of importing materials.

Mattresses from Brooklyn Bedding include a 10-year warranty. They have a 120-day sleep trial period, but you must try out your new mattress for a minimum of 30 days.

Again, the Aurora mattress isn’t the cheapest, but its breathability, minimal motion, and firmness are hard to beat. It’s made right here in the USA and doesn’t have much of a scent when you unpack it. All of these reasons, plus the quality layers of foam, make this a good choice for hot sleepers seeking a firm mattress.

Why we like it:

  • Open-cell foam prevents heat buildup
  • Environmentally friendly materials
  • Stable, comfortable cushioning
  • Made in the United States
  • Cover made with Celliant®

The AS1 is the firmest option available from Amerisleep. Memory foam is usually associated with feeling hot. But the AS1 uses a structure that keeps the airflow going, so you won’t wake up sweaty. And the Bio Core foam used in the foundation won’t sag, even years down the road.

You Might Want To Pick The To Pick the AS1 If:

  • You need help staying asleep at night: The AS1 mattress uses a product called Celliant® in their mattress covers. This converts your natural body heat into energy for temperature control. Studies show that this material improves the quality of rest you get while you sleep.
  • You want breathable foam in your mattress: This mattress uses Bio-Pur foam, which is very breathable compared with ordinary memory foam. Due to its special design, it soaks up your body heat and keeps you cool.
  • You suffer from lower back pain: This mattress is very firm and won’t allow your hips to sink far into it. Because it keeps your hips aligned this way, you won’t wake up with a sore lower back. Stomach sleepers will also appreciate this mattress because it keeps your spine comfortably aligned in this position.
  • You move around in your sleep: The AS1 uses memory foam which responds slowly to pressure. But, because there are only 2 inches of this foam, you can easily shift positions without getting stuck or sinking in.

The AS1 mattress by Amerisleep uses a thinner layer of memory foam, which gives you pressure relief and contours around your body. The firmness of this mattress comes from the 8-inch base, which is made of dense poly-foam. Although there is the top soft layer in place, you will comfortably sink right through it to the firm layer. This offers a supportive sensation for your body and acts as the mattress foundation.

If you sleep with a partner who is changing positions, you will feel very little motion from this. Due to the memory foam used, the disturbance is muffled. Although you may feel it slightly when your partner gets into or out of bed, it won’t cause as much rebound as a bouncier mattress. Other Amerisleep mattresses are better at absorbing motion, but they also aren’t as firm.

Both layers of foam use plant-based materials, which is more environmentally friendly than petroleum. This process is designed to cause less harm to the planet and more than meets the guidelines of the US Clean Air Act.

Amerisleep offers a 20-year warranty with this mattress. They also give you 100 nights to test it out and will give you a complete refund if you aren’t pleased. They will even pick the mattress up for you if you decide to return it.

Reviews suggest that this mattress will remain firm, even after years of use. Many reviewers have been impressed with the cooling sensation on this mattress. And it offers a quicker bounce response time than softer mattresses. If you’re seeking an eco-friendly choice and better back support, this could be the best choice.

The mattress is 10-inches thick in total with a 2.5-inch comfort layer made from memory foam.

Live and Sleep use an eco-friendly manufacturing process which reduces the number of volatile chemicals being released into the air. They are CertiPUR-US certified, meaning that the materials they use are safe and free from lead or mercury.

It only requires a short period to breathe with an open window nearby and it’s ready to sleep on! Plus, when you order the Memory Foam Elite, you will get a free non-toxic, eco-friendly Visco-elastic pillow.

The soft side of the Layla Mattress has a 3-inch layer of memory foam, infused with copper. This responds slowly to pressure and contours to your body. Below this is a 2-inch poly foam transition layer that adds support. It also regulates temperature due to its egg crate design. The supportive center responds quickly to pressure and helps the mattress keep its shape.

On the firm side of this mattress, there’s a 1-inch memory foam layer which keeps you from sinking in, but still contours. It has no transition layer, so contouring is minimal, although it will still feel plenty comfortable. Both the firm and soft side of the Layla Mattress do a good job isolating motion.
