Invest in deep comfort.

If you are a side sleeper, you really need a mattress that is soft enough to form to your body, without being so soft you sink in. An ideal mattress for those of us that sleep on our sides, the Puffy Royal relieves pressure all night long. Those who favor a different sleeping position, for example back sleepers, may find the Puffy Royal still provides enough support, while providing optimal comfort.

The Puffy Royal stands at a height of 14” making it one of the tallest mattresses on our list. Composed of 5 foam layers and boasting zoned construction, the Royal provides support where you need it and contouring comfort where you want it most. Overall, the mattress has a medium-soft feel. The deep contouring provides a gentle hug-like sensation that works exceptionally well for side sleepers, in many reviews being likened to sleeping on a cloud.

Like many memory foam mattresses, the Puffy Royal infuses its foam with cooling gel beads which helps to reduce heat retention. Additionally, the Royal is also designed for enhanced breathability! Not only does the foam feature an open-cell design but the zoned support foam includes miniature cloud cutouts across the entire surface. These cutouts act as channels to promote airflow, meaning the Royal could be a good fit for anyone who sleeps hot.

The comfort layer and reflex layer allows the mattress to form to you without leaving you feeling stuck in bed. The next layers of memory foam and poly foam are designed to offer a slow response for contouring and solid support at the base. The smart combination of slow-response and quick-response foam provides a luxury feel with amazing support. Last but not least, the mattress cover is moisture-wicking and stain-resistant, it’s also machine washable, making it easy to clean and maintain the health and hygiene of your mattress.

Ultimately, the Puffy Royal is designed for luxury and it hits the mark.

The Snuggle-Pedic Mattress - Best Cooling Mattress + Breathability

Snuggle-Pedic Mattress Review

Keep calm and dream on.

If you are a hot sleeper that wakes up in a sweat more often than not, you are going to be looking for the coolest mattress options. We rate Snuggle-Pedic high for it’s cooling qualities.

Memory foam mattresses are a top choice for those looking for contouring and pressure relief, in particular, those who suffer from pain related to fibromyalgia or sciatica. Traditionally, however, memory foam was also known to trap heat. But there are options for mattresses that are designed for breathability and offer cooling components!

Snuggle-Pedic addressed this common problem by creating a patented Airflow Transfer System® to help mitigate heat retention and, increase the breathability of the mattress, providing a cooler sleeping experience. The Airflow Transfer System® features thousands of small pinholes across the top layer of memory foam. These pinholes work with the base layer, which is lined with grooved channels, making the Snuggle-Pedic mattress significantly more breathable than other memory foam mattresses. And it’s covered in a Kool-Flow®, ultra-breathable and soft to the touch, bamboo cover.

The Snuggle-Pedic Deluxe memory foam mattress provides a medium-firm feel that we think is best suited to back sleepers. Favor a different sleep position? Snuggle-Pedic has you covered there too, they offer two other models: the Original Hybrid (better for stomach sleepers) and the Supreme Plush (best for side sleepers).

The Snuggle-Pedic nails high-end foam mattress technology for cool and comfortable sleep.

The Amerisleep AS3 - The Best Mattress for Back Pain

Amerisleep Mattress Review

No more straining on your mattress choice.

An estimated 80% of Americans will experience back pain at some point in their lives. If this is a deciding factor for you, then you are certainly not alone. Amerisleep is a top mattress for reducing back pain.

With 5 different firmness options to choose from, Amerisleep not only has a mattress to suit every sleep position, it’s a great option for anyone who suffers from back pain. From the plush, deep contouring of the AS5 to the firm support of the AS1, Amerisleep has your needs covered.

Amerisleep’s most popular model, the AS3, is a versatile mattress that blends support and comfort seamlessly, while promoting proper alignment for a healthy spine, a key component in combatting back pain.

In addition to being a top pick for back pain sufferers, Amerisleep is a solid choice for anyone who sleeps hot. Made from eco-friendly, plant-based foam, Amerisleep features an open-cell design that enhances the breathability and cooling benefits of the mattress.

And because you’ll be sleeping more “on” the mattress than in it, it’s also a solid choice for couples and combination sleepers. The Bio-Pur® foam is quick to bounce back, does an excellent job of reducing motion transfer and eliminates any sense of being stuck in the mattress. This also makes it a great choice if you tend to be a restless sleeper with a lot of movement at night.

Follow your budget without sacrificing quality.

A new mattress isn’t cheap and that can be hard if you aren’t ready to make a big investment. If you are looking for the best cheap mattress options, then look no further than Nectar.

The Nectar mattress provides loads of deep contouring and pressure relief for a classic memory foam feel. The top layer of gel-infused memory foam has a slow bounce back allowing you to really sink into the layers for a deep cradling sensation that melts away pressure.

Overall, Nectar has a medium firmness that supports a wide range of sleeping positions. You’ll find yourself sleeping “in” this mattress rather than on top which can make it a wonderful option for side sleepers. At the same time, the base layer provides enough support to make it a suitable choice for back and even some stomach sleepers.

When it comes to value, few mattresses pack a punch like Nectar. Nectar comes with a 365-night sleep trial—one of the longest sleep trials in the industry. This gives you plenty of time to make sure your choice was the right one and not just the most affordable one. They also offer a lifetime warranty to back their product.

Not only is this one of our favorite beds, it is one of the least expensive we’ve reviewed. The queen-size Nectar mattress starts at $799. Even better, Nectar runs some excellent deals and discounts such as free accessories with the purchase of a mattress.

Nectar is the best at offering a sweet deal for renewed sleep.

Zoma - Best for Active Lifestyles

Zoma Mattress Review

Work hard, sleep harder.

When you are busy and active, your body is often pushed to its max. We are impressed with how the Zoma mattress provides recovery technology and increased breathability. Zoma makes no bones about its audience, marketed towards athletes and active individuals, the Zoma mattress is designed for “enhanced rest and rejuvenation”.

But let’s be honest, everyone benefits from better sleep and recovery, not just athletes. So, we are recommending this mattress if you are looking for the best mattress for a busy lifestyle, regular physical exertion or just an exhausted adult in general.

At 11” in height, Zoma sports a seemingly simple three-layer foam design. But once you really dig under the cover, you can see what sets this mattress apart. The top layer features a proprietary foam that includes hundreds of triangular cutouts that provide excellent cushion and pressure relief. These cutouts also work as air channels, increasing the breathability of the mattress.

The latex-like transition layer keeps you from sinking too deeply into the mattress so you won’t feel trapped in the foam layers. Instead, you may feel more like you are floating on top of the mattress. It is medium-firm, which can provide support and relieve pressure. The mattress works well for a wide variety of sleeping positions including side, back and combination sleepers, and it is a solid choice for anyone who sleeps hot.

With a queen priced at $850 before discount, Zoma is affordable and ticks a lot of boxes.

Frequently Asked Questions About Memory Foam Mattresses

Q: What is a memory foam mattress made of?

Invented in the 1960s for NASA, the padding material in a memory foam mattress consists of polyurethane and other chemicals designed to increase viscosity and density. These chemicals can include polyols, diisocyanates, formaldehyde, benzene, and napthalene, among others. A memory foam mattress is usually denser than other foam mattresses, making it both more supportive and heavier.

Q: How Can I Choose A Safe Memory Foam Mattress?

The following steps will allow you to minimize health risks when choosing a memory foam mattress:

        • Opt for plant-based memory foam, such as that found in the Amerisleep mattress. Not only do they reduce the use of petrochemicals, they increase the breathability and cooling of the mattress.
        • Look for mattresses with CertiPUR-US and/or Greenguard Gold certifications. These certifications ensure your mattress will have low VOC emmissions.Opt for foams made in the US or Europe, as these foams are held to stricter regulations.
        • Choose a mattress with a natural fire retardant sock, such as wool. If this is not available, look for CertiPUR-US certifications which ensure that the fire sock does not contain BPDEs, TDCPP, or TCEP flame retardants.

Q: Will a memory foam mattress make me hot while sleeping?

Many memory foam mattresses have an issue retaining body heat because memory foam is a dense material and lacks interconnected air channels. However, there are memory foam mattress options available that have gel or copper-infused memory foam or have added air channels to improve ventilation. The Snuggle-Pedic Deluxe Comfort memory foam mattress has a patented Airflow Transfer System and the Nectar Lush mattress has a Tencel Cooling Cover which promotes breathability and pulls heat away from the mattress.

Q: What foundation should I use under a memory foam mattress?

A bed foundation is critically important to a mattress’s performance and your comfort. Sleeping on the wrong foundation can cause your mattress to prematurely dip and sag, so proper support is a must. At the same time, certain foundations may cause heat to become more readily trapped inside your memory foam mattress. While most foundations and frames should work for your new mattress, foundations that have spaces to let air flow through the bottom and clear out accumulated heat may prevent overheating best.  Zoma, recommends a foundation with slats no more than 3 inches apart and at least 0.5 inches thick.

Q: What is ILD?

ILD or Impression Load Deflection,  is the measure of the softness or firmness of a foam mattress. The higher the ILD, the firmer the mattress. It is measured by pressing a 12-inch round disk into a 4-inch piece of foam until it presses 25% or one inch into the mattress surface. The amount of pressure needed to compress the mattress to that extent is the ILD.

Q: What is the ILD for the memory foam?

Most memory foam mattresses on the market rate between 10 and 16 ILD.

Q: How long does a memory foam mattress last?

High quality memory foam mattresses can last between 8 and 10 years when properly cared for. While factors such as weight and frequency of use can affect the lifespan of your mattress, choosing medium to high density foams over low density foams can significantly increase the life expectancy. Amerisleep states that the “goldilocks” range for most sleepers is between 4.0-5.3 lbs in the comfort layer, providing the ideal balance between comfort and durability.

Q: What is the difference between an innerspring mattress and a memory foam mattress?

Memory foam mattresses are known to provide exceptional comfort. Using your body’s heat, memory foam contours and relieves pressure as it moulds to your curves. Innerspring mattresses feature springs or coils which provide more responsiveness and bounce. The coils also allow for greater airflow. In general, innerspring mattresses provide a cooler, more breathable sleep experience. Hybrids are an increasingly popular pick for those who which to combine the best qualities of memory foam and innerspring mattresses..

Q: Does Sleep Number make a memory foam mattress?

Yes, Sleep Number’s m7 SMART BED is a memory foam bed. It has cooling memory foam and has the added benefit of Sleep Number’s adjustability enhancements.

Q: Is a memory foam mattress good for allergies?

Memory foam has anti-microbial and anti-dust mite properties which creates a healthier sleeping environment. Latex and memory foam mattresses are generally considered top picks for those who suffer from allergies.
