NAPSIE 6 Inch Full Mattress in a Box, Green Tea Memory Foam Mattress with Review
The NAPSIE 6 Inch Full Mattress is a bed-in-a-box memory foam mattress designed for sleepers seeking a balance of support and cooling comfort. It features a green tea gel-infused memory foam layer that actively regulates temperature and wicks away moisture. This mattress aims to reduce night sweats and neutralize odors while providing medium-firm support suitable for all sleep styles. Its 6-inch profile offers a streamlined sleep surface that conforms to body contours for pressure relief. The mattress arrives compressed in a box for easy setup and expands to its full size within 24 hours. It is compatible with various bed frames including box springs, adjustable bases, slatted platforms, and even the floor. CertiPUR-US and OEKO-TEX Standard 100 certifications ensure it is free from harmful chemicals and volatile organic compounds. A 10-year limited warranty provides long-term peace of mind for buyers.
Product Overview
The NAPSIE mattress is a full-size model measuring 75 inches long by 54 inches wide by 6 inches thick. It weighs approximately 33 pounds, making it relatively lightweight for easy handling during setup. The mattress construction centers on green tea gel-infused memory foam, which serves as both the comfort layer and primary support system. This gel infusion is designed to enhance temperature regulation by dissipating heat and promoting airflow. The cover is made from a polyester blend fabric that is breathable and easy to clean with a convenient zipper. The medium firmness level is intended to accommodate back, side, and stomach sleepers by offering contouring support without excessive sinkage. It is marketed as suitable for both kids and adults. The mattress is fiberglass-free, addressing common concerns about fiberglass particles in some budget mattresses. Setup involves unboxing the compressed mattress, placing it on a supportive surface, and allowing up to 24 hours for full expansion and off-gassing. The compact packaging simplifies delivery through standard doorways and staircases. While the 6-inch thickness may be thinner than many all-foam mattresses, it provides a firmer feel that works well on solid foundations. The mattress cannot be returned once opened, so buyers should confirm size and firmness preferences before purchase.

Design & Build
The NAPSIE mattress features a straightforward single-layer construction with green tea gel-infused memory foam as its core material. This 6-inch thick foam block is designed to provide both comfort and support without additional transition or base layers. The gel infusion is evenly distributed throughout the foam to enhance thermal conductivity and prevent heat buildup. The mattress cover is made from a polyester blend fabric that is stretchable and breathable, promoting airflow across the sleep surface. A full-length zipper allows the cover to be removed for cleaning, though the foam core itself is not washable. The edges are finished with reinforced stitching to maintain shape integrity over time. The overall design prioritizes simplicity and functionality, with a low-profile silhouette that works well in modern bedroom setups. The absence of fiberglass in the fire barrier makes it a safer choice for households concerned about particle exposure. The mattress arrives tightly compressed and vacuum-sealed in plastic, reducing its packaged size for convenient shipping through narrow spaces. Unboxing reveals a faint off-gassing odor that dissipates within a few hours to a day, which is typical for memory foam products. The cover's neutral white color with subtle texturing gives it a clean, minimalist appearance that blends with most bedding styles. While the 6-inch thickness may feel firmer than thicker mattresses, it provides adequate support for average-weight sleepers and works best on a solid, flat foundation to prevent sagging.
Performance
The green tea gel-infused memory foam aims to address common heat retention issues in traditional memory foam. The gel particles help dissipate body heat, maintaining a cooler sleep surface compared to non-infused foams. This temperature regulation can reduce night sweats and improve comfort for warm sleepers. The foam's slow-response contouring adapts to body shapes, cushioning pressure points at the shoulders, hips, and lower back. The medium firmness offers a balanced feel that is neither too plush nor too rigid, suitable for combination sleepers who change positions. Edge support is moderate due to the single-layer construction, with some compression when sitting near the perimeter. Motion isolation is effective, minimizing disturbance from a partner's movements during the night. The mattress maintains its shape well over time, though thinner profiles may show slight indentations with prolonged use. The polyester cover resists stains and moisture, and its removable design simplifies spot cleaning. The mattress works on various foundations but performs best on solid platforms or slatted bases with minimal spacing to prevent uneven support. Its lightweight build makes it easy to reposition or rotate for even wear. While no reviewer feedback is available, the manufacturer claims the foam provides consistent support and cooling benefits throughout its lifespan. The 10-year warranty covers defects in materials and workmanship, offering reassurance against premature sagging or material breakdown. Overall, this mattress delivers reliable performance for budget-conscious buyers seeking basic memory foam comfort with enhanced cooling features.
