10 Best 6 Inch Full Mattress 2025 in the United States

The ZINUS 6 Inch Green Tea Memory Foam Mattress is a solid choice for anyone looking for a budget-friendly full-sized mattress. Its three layers of foam, infused with refreshing green tea and charcoal, aim to provide a comfortable sleeping experience that supports your body’s curves. The patented Custom Contour technology promises to deliver excellent support, helping to alleviate pressure points, which is a significant plus for those who often wake up with aches and pains.

When it comes to firmness, this mattress leans towards a medium-firm feel, making it suitable for a variety of sleepers, including side, back, and stomach positions. The CertiPUR-US certification ensures that the foams used are of decent quality and free from harmful chemicals, which is reassuring for health-conscious consumers.

One of its standout features is the motion isolation, which can be particularly beneficial for couples. With this mattress, movements on one side are less likely to disturb the other, allowing for a more undisturbed sleep. However, there are a few drawbacks to consider. The 6-inch thickness may not provide enough support for heavier individuals or those who prefer a more plush feel. Additionally, while it does a decent job at temperature regulation, some users might still experience heat retention typical of memory foam, especially in warmer climates. The recommended expansion time of 24-72 hours can also be inconvenient if you're eager to use your new mattress right away.

Lastly, while the 10-year limited warranty is a great assurance, some users might wish for a longer warranty period considering the investment. This mattress is particularly well-suited for budget-conscious individuals or those transitioning to memory foam, but it may not meet the needs of everyone, especially larger individuals or those in warmer regions.

The ZINUS 6 Inch Green Tea Memory Foam Mattress offers a balanced mix of comfort and support, thanks to its memory foam and high-density foam layers. The medium firm feel is well-suited for those who prefer a mattress that is not too soft but still provides adequate support. The mattress excels in pressure relief, as it conforms to the body and helps enhance circulation, which can be beneficial for reducing aches and pains. Additionally, the green tea and purified charcoal infusions help keep the mattress fresh, which is a nice bonus for long-term use.

The mattress is made from CertiPUR-US certified foam and OEKO-TEX certified cover, ensuring it is free from harmful chemicals, making it a safer choice for health-conscious individuals. However, its 6-inch thickness may not provide sufficient support for heavier individuals or those who prefer a thicker mattress for added comfort. The mattress also comes with a 10-year limited warranty, offering some peace of mind.

Despite its thinner profile, it can support up to 500 pounds for full-size, which is impressive. The mattress ships in a compact box, which is environmentally friendly and convenient for handling. On the downside, some users may find the firmness level too hard, and it may take 24-72 hours to fully expand after unboxing. This mattress is a suitable option for those looking for an eco-friendly, medium-firm, and affordable sleep solution, but it may not be ideal for individuals requiring thicker support or those with a preference for a softer feel.

The GAESTE 6 Inch Full Cooling Memory Mattress offers a medium firmness that suits those looking for a good balance between softness and support. Its gel memory foam material is designed to keep you cool throughout the night, which is a plus if you tend to sleep hot. The mattress uses CertiPUR-US certified foam, meaning it's made without harmful chemicals, and it comes with a washable OEKO-TEX certified cover, making it easy to keep clean.

At 6 inches thick, it’s thinner than many traditional mattresses, so while it provides decent pressure relief and support for lighter individuals or guest beds, it may not suit heavier sleepers who need more cushioning. The mattress is also well-rated for motion isolation, so if you share the bed, you’re less likely to be disturbed by your partner’s movements.

Durability-wise, thinner foam mattresses like this one might wear out quicker than thicker models, but the certifications suggest reasonable quality for the price. Its compact, mattress-in-a-box design means it’s easy to set up quickly, which is convenient. This mattress is a strong choice for budget-conscious buyers or those needing a comfortable, cooling mattress for occasional or lighter use, but it might not be ideal as a primary mattress for heavy sleepers or those seeking a very plush feel.
