Full Size Mattress Size Buying Guide for 2026
Choosing the right full size mattress size comes down to a few key factors that affect comfort, durability, and how well the mattress fits your lifestyle. Use this buying guide as a checklist while you compare the 10 models featured above. Here is what matters most.
Thickness and Profile
When you shop for a full size mattress size, the first thing to evaluate is thickness. Full size mattresses typically range from 6 to 12 inches. A 6 inch profile, like the Gelsea 6 Inch Full Size Mattress or the EGOHOME 6 Inch Full Size Mattress, keeps a low silhouette and works well for platform beds, bunk beds, or kids transitioning from a crib. An 8 inch profile is the most common choice for guest rooms and everyday use because it balances comfort and portability.
For sleepers who want a more substantial feel, 12 inch models such as the Full Size 12 Inch Hybrid Mattress and the Full Mattress 12 Inch Hybrid Sleep Bed provide additional support layers and a taller side profile that makes getting in and out of bed easier. Your bed frame also matters. If you use a low platform bed or a box spring, a thinner mattress may be enough. If you prefer a taller bed or suffer from joint pain, a thicker mattress with multiple foam layers and pocket coils can offer better pressure relief.
Material and Construction
Memory foam and hybrid are the two main construction types you will encounter. All foam mattresses, such as the Novilla Full Size Mattress and the EGOHOME Full Size Memory Foam Mattress 8 Inch, provide excellent contouring and quiet, motion absorbing support. They are also easier to compress and ship in a box. Hybrid mattresses, like the Full Size 12 Inch Hybrid Mattress, combine gel memory foam with individually wrapped coils. This gives you both pressure relief and springy support, plus better airflow around the core.
The LETMOON Luxury Full Size Mattress 8 Inch uses a hybrid design with 7-zone pocket springs, making it a standout for targeted ergonomic support. The choice between foam and hybrid often comes down to personal preference. Side sleepers may love the deep cushioning of memory foam, while back and stomach sleepers might prefer the firmer, more resilient feel of a hybrid. If you share the bed, hybrid models with pocket coils usually minimize motion transfer while keeping the surface responsive.

Firmness and Sleep Position
Firmness plays a huge role in how comfortable and supportive a full size mattress size feels. Most manufacturers label their beds as medium firm, which is a safe middle ground for combination sleepers. The EGOHOME Full Size Mattress 8 Inch Medium Firm and the 12 Inch Full Size Mattress are both designed to fall in this sweet spot. If you want a firmer surface for back or stomach sleeping, the Gelsea 6 Inch Full Size Mattress offers firm support that keeps hips and shoulders level.
For a slightly softer, hugging sensation, memory foam options from Novilla and EGOHOME relieve pressure on the shoulders and hips. Before you decide, think about your usual sleeping position. Side sleepers generally need a little more give to cushion the shoulder and hip. Back sleepers need even support along the spine. Stomach sleepers need a firmer surface to prevent the midsection from sinking too deeply. A medium firm full size mattress size works for many users, but reading the manufacturer’s description and customer feedback can help you fine tune your choice.
Motion Isolation
Motion isolation is a critical factor if you sleep with a partner, a pet, or even a restless child. Memory foam naturally absorbs movement, so all foam mattresses like the Novilla Full Size Mattress are excellent at preventing motion transfer. Hybrid mattresses with individually wrapped coils also isolate motion well, provided the coils are not interconnected. Models like the Full Mattress 12 Inch Hybrid Sleep Bed and the LETMOON Luxury Full Size Mattress 8 Inch go a step further with reinforced pocket springs that reduce cross mattress movement.
When you are comparing full size mattress size options, look for terms like “independently encased coils” or “pocket springs” in the specifications. These features allow each coil to respond separately to pressure, so when your partner turns over at night, the movement stays localized. A mattress with good motion isolation can dramatically improve sleep quality for light sleepers.
Cooling and Breathability
Overheating is a common complaint with traditional memory foam, but modern full size mattresses use several technologies to tackle this issue. Look for gel infusions, open cell foam, and breathable covers. The Novilla Full Size Mattress adds extra NanoGel to its top layer to increase heat absorption and promote airflow. The EGOHOME Full Size Mattress 8 Inch Medium Firm infuses green tea and cooling gel into its AeroFusion memory foam, while the LETMOON Luxury Full Size Mattress 8 Inch uses a 3D knitted fabric to wick away heat and sweat.
If you tend to sleep hot, also consider the mattress cover. Many models, including the EGOHOME Full Size Mattress 8 Inch Medium Firm, feature a removable jacquard cover that is breathable and easy to wash. The Gelsea 6 Inch Full Size Mattress uses a moisture wicking poly-rayon cover to keep the surface dry. Ventilated foam layers and cooling gels are your best friends in a warm climate.
Certifications and Safety
Safety and material quality matter just as much as comfort. All of the full size mattresses we selected for this roundup are made with CertiPUR-US certified foams, which means they meet strict standards for content, emissions, and durability. Several models, such as the EGOHOME Full Size Mattress 8 Inch Medium Firm, are also fiberglass free and use an OEKO-TEX Standard 100 certified fabric. The Full Size Mattress, 12 Inch Gel Memory Foam Hybrid includes CertiPUR-US and OEKO-TEX certifications as well as CFR 1633 fire safety compliance.
When choosing a full size mattress size for a child or someone with allergies, fiberglass free construction and low VOC emissions are important. Certifications give you peace of mind that the materials inside the mattress have been independently tested. Always check the product listing for certification labels before you buy.

How many inches should a full size mattress be?
Full size mattresses usually come in 6, 8, 10, or 12 inch profiles. An 8 inch mattress is a popular choice because it suits most sleepers and bed frames. If you want more support and a taller bed, a 12 inch model is a good option.
What are the dimensions of a full size mattress?
A full size mattress measures 75 inches long and 54 inches wide. It provides 15 inches more width than a twin mattress, making it a comfortable choice for a single adult or a cozy option for two people.
Is a hybrid mattress better than memory foam for a full size bed?
It depends on your preferences. Hybrid mattresses like the Full Size 12 Inch Hybrid Mattress offer a mix of foam comfort and coil support, which provides more bounce and airflow. Memory foam mattresses like the Novilla Full Size Mattress contour closely and absorb motion better. Consider your sleeping position and whether you tend to sleep hot.
Can I use a full size mattress on a bunk bed?
Yes, if the bunk bed frame is designed for a full size mattress. Check the recommended mattress thickness for your bunk bed, especially if there is a guard rail. A 6 or 8 inch mattress, like the EGOHOME 6 Inch Full Size Mattress or the LETMOON Luxury Full Size Mattress 8 Inch, is often a safer fit for bunk beds.
