The pressure-relieving memory foam is the core of its supportive nature, conforming closely to your body’s shape. This helps to enhance circulation and decrease stress on joints, providing rejuvenating support that adapts to your sleeping position.

Its gel memory foam is designed to support all parts of the body evenly and individually, which can be particularly beneficial for those who need more firm support to maintain spinal alignment. The balanced construction prevents the feeling of sinking too deeply into the mattress.
A key feature of this mattress is its gel infusion, which actively works to absorb excess heat while you sleep. This cooling process can help you fall asleep more quickly and comfortably. The gel component also contributes to the mattress’s durability, making it less prone to damage and helping it maintain its supportive shape over a long period of time.

The all-foam construction is built for pressure-relieving comfort. Layers of comfort foam and memory foam contour precisely to your body’s shape, helping to align the spine and distribute weight evenly. This targeted support helps to alleviate pressure points at the shoulders and hips, making it a strong option for side sleepers and those with back pain.

Buying Guide: How to Choose a Full Size Memory Foam Mattress for Support
When I started looking for a new mattress, I knew I wanted the pressure relief of memory foam, but I was worried about getting enough support. A mattress that’s too soft can leave you with aches and pains, which defeats the whole purpose. After a lot of research and testing, I figured out what really matters when you’re searching for the best full size memory foam mattresses for support.
First, let’s talk about foam density. This is a big one. Density is measured in pounds per cubic foot (PCF). For a supportive memory foam mattress, look for a top comfort layer with a density of at least 4 PCF. Lower-density foam might feel soft at first, but it breaks down faster and won’t support your spine properly over time. A higher-density foam provides that classic “hug” without letting you sink too far, which is key for keeping your spine aligned.
Next, consider the overall construction. Most supportive memory foam mattresses aren’t just one big block of foam. They are built in layers. You’ll typically see a base layer of very firm, high-density support foam. On top of that, there’s often a transition layer, sometimes made of a more responsive foam like polyfoam or latex, to prevent that “stuck in the mud” feeling. Finally, the top comfort layer is the memory foam itself. This multi-layer approach is what creates a balance between cushioning and lift. Some of the most supportive models even use zoned support, where the foam is firmer in the middle third of the mattress to support your hips and softer at the head and feet.
Firmness level is another personal but crucial choice. Support doesn’t always mean rock-hard. It means the mattress keeps your spine in a neutral position. Side sleepers often need a medium to medium-soft feel to allow their shoulders and hips to sink in just enough. Back and stomach sleepers usually need a medium-firm to firm feel to prevent their lower back from sagging. Many online brands offer a firmness scale on their website, which is super helpful.
Finally, don’t forget about the trial period and warranty. A long sleep trial (think 100 nights or more) lets you actually sleep on the mattress to see if it supports your body. A good warranty, often 10 years or longer, protects you against premature sagging and defects, which are clear signs of a support failure. Paying attention to these details will help you find a mattress that feels great and supports you properly for years to come.
Frequently Asked Questions
Is a full size memory foam mattress supportive enough for two people?
It can be, but it depends on your needs. A full size mattress provides enough space for two people, but it’s a bit cozier than a queen. The support itself comes from the quality and density of the foam layers, not the mattress size. If you and your partner are average-sized and don’t mind sleeping close, a supportive full size model can work well. However, if one or both of you are taller or move around a lot, you might want to consider a queen for more space, as feeling cramped can affect your perception of comfort and support.
Will a memory foam mattress sleep hot?
This was a common issue with older memory foam, but many modern mattresses are designed to tackle this. Look for features like gel infusions, copper infusions, or open-cell foam structures. These technologies are meant to pull heat away from your body and improve airflow. Some mattresses also have covers made from breathable materials like cotton, Tencel, or phase-change material. If you tend to sleep hot, prioritizing a bed with these cooling features is a good idea.
How long does a full size memory foam mattress typically last?
A high-quality memory foam mattress should last between 7 to 10 years. Its lifespan is directly tied to the quality of its materials, especially the foam density. A mattress with high-density foam layers will resist sagging and body impressions much longer than one made with low-density, less expensive foam. Following the manufacturer’s care instructions, like using a supportive foundation and rotating the mattress head-to-foot every few months, can also help extend its life.
Do I need a special bed frame or base for a memory foam mattress?
Most memory foam mattresses are compatible with any firm, flat, and stable surface. This includes a traditional bed frame with a bunkie board, a slatted foundation with slats no more than 3 inches apart, an adjustable base, or even placed directly on the floor. The critical thing to avoid is a saggy or widely-spaced slatted base, as it won’t provide consistent support and could void your warranty. Always check the manufacturer’s recommendations for your specific model.
What is the difference between memory foam and other foam types?
Memory foam is known for its slow-response, contouring feel—it sinks and molds to your body’s shape. Other common foams, often called polyfoam or responsive polyfoam, are bouncier and react more quickly to pressure. Many of the best full size memory foam mattresses for support actually combine both. They use memory foam on top for pressure relief and a responsive polyfoam underneath or in transition layers to add lift and prevent that sinking feeling, creating a more balanced and supportive sleep surface.
How long does it take for a new memory foam mattress to fully expand?
While most mattresses will expand to their full size within a few hours, it’s normal for there to be a slight “new mattress smell” (which is harmless off-gassing) and for the foam to feel a bit firmer than expected at first. I recommend giving it at least 24 to 48 hours to fully air out and expand. However, it might take your body a few weeks to adjust to the new feel, and the foam may soften up slightly as you break it in.
