10 Best Mattress 6 Inches 2025 in the United States

The ZINUS 6 Inch Green Tea Memory Foam Mattress is a good choice if you're looking for a medium-firm mattress that combines comfort with affordable pressure relief. It uses memory foam infused with green tea and charcoal, which helps keep the mattress fresh and may reduce odors over time. The patented zoned pressure relief technology is designed to ease aches and pains by contouring to your body and supporting joints well. Thanks to its CertiPUR-US certified foam and OEKO-TEX certified cover, this mattress avoids harmful chemicals, making it a healthier option for allergy sufferers.

At 6 inches thick, the mattress is thinner than many others, so it might be best suited for lighter individuals or those who prefer a firmer base feel rather than deep plush softness. It supports up to 500 pounds for queen size, which covers most users comfortably. Breathability is decent due to the infused materials, though memory foam mattresses can sometimes trap heat, so very warm sleepers might want to consider that. The mattress also isolates motion well, which is great if you share your bed and don't want to feel every toss and turn.

Durability should be reasonable given the high-density foam layers, but thinner mattresses like this may not last as long as thicker models, especially for heavier use. It comes compressed in a box for easy setup, though it can take up to 72 hours to fully expand. The 10-year limited warranty adds peace of mind. This mattress is best suited for those wanting a firmer, medium support level with natural freshness features, especially if you need an affordable, chemical-free option. If you prefer a very plush feel or need extra thickness for added cushioning, you might find this model a bit thin.

The EGOHOME 6 Inch Full Size Mattress is made from memory foam infused with green tea gel, which helps keep the mattress cool and breathable—an important feature if you tend to get warm at night. Its medium firmness offers balanced support that adapts to different sleeping positions, which can be great for kids or adults who move around a lot during sleep. The memory foam relieves pressure on joints and muscles, helping to reduce discomfort and promote better blood circulation.

Because it’s made from CertiPUR-US certified materials and is fiberglass-free, it’s safer and less likely to cause allergies or irritation. The mattress also isolates motion well, so if sharing a bed, you won’t be disturbed much by movement. Being 6 inches thick, it’s a good choice for kids or those who prefer a thinner mattress, but it might not provide enough deep support for heavier adults or those who prefer a very plush or very firm mattress. Its durability is solid for this thickness, but it may compress faster than thicker mattresses over time. The cover is a polyester blend, which is easy to clean but may not feel as soft as natural fabrics.

This mattress is well suited for kids or anyone seeking a medium-firm, breathable, and pressure-relieving mattress with a focus on safety and cooling.

The ZINUS 6 Inch Green Tea Memory Foam Mattress offers a unique combination of green tea and charcoal-infused memory foam, which provides a refreshing and moisture-absorbing sleeping surface. This mattress is designed to contour to your body, easing pressure points and supporting a comfortable night's rest. The patented Custom Contour Support technology ensures that you won't feel like you're sinking, which is ideal for those seeking a balanced level of firmness and support.

The mattress is CertiPUR-US certified, guaranteeing high-quality foam that is free from harmful chemicals and substances, making it a safe choice for individuals with allergies. A standout feature is its fiberglass-free construction, contributing to a healthier sleep environment. It's also conveniently packaged in a compact box, so setup is simple—just unbox, unroll, and allow it to expand within 24-72 hours.

However, it's worth noting that the 6-inch thickness may not provide sufficient support for heavier individuals or those needing more cushioning. Also, while it does offer decent breathability with its cotton cover, it may not be as breathable as other materials like latex or hybrid options. Its motion isolation is adequate for a twin size, but may not be as effective for couples sharing a larger bed. The mattress comes with a 10-year warranty and supports up to 250 lbs for the twin size, providing excellent value for its price point.
