​Enjoy superior comfort when resting on the three layers of supportive memory foam found in this 8-inch memory foam mattress. The top layer of green tea infused gel aerofusion memory foam gently cradles your body to ease pressure points and provides odor control for more refreshing sleep. The middle layer consists of ventilated flex comfort foam that features liquid cooling gel swirled into the foam to promote heat dissipation for cooler rest and enhanced air circulation. The base layer of flex support foam provides long-lasting durability and support so you can rest peacefully for years to come. The durable circular knit cover offers luxurious softness for enhanced comfort, while the non-skid bottom ensures the mattress will not slide or shift atop your bed frame or box spring. This memory foam mattress can be used on all foundations including adjustable beds and does not require a box spring. Each mattress-in-a-box conveniently ships directly to your home. Simply remove the compressed mattress from the packaging, unroll and lay on a flat surface, wait 48 hours to allow the mattress to fully expand and release trapped odors, then relax on your new comfortable mattress.  Mattress Top Type: Tight Top Mattress Type: Gel Memory Foam, Mattress In A Box Included: 1 Mattress(es) Features: Foam Layer, Antimicrobial, Full Support, Mattress In A Box, Fire Resistant, Adjustable Base Compatible Additional Information: Conforms To Body, Relieves Pressure Points, Eliminates Motion Transfer, Suitable for Adjustable Bed Frames Manufacturer Warranty: 10 Year Limited Bed Size: Twin Xl Measurements: 10 Height/Inches, 39 Width/Inches, 80 Length/Inches Maximum Weight Limit: 300 Lbs Base Material: 100% Polyurethane Comfort Type: Medium Care: Spot Clean Certifications And Listings: Certipur-Us Certified Mattress Height: 10" Country of Origin: Imported Visit our Furniture & Mattress Customer Care Center for delivery options, protection plans and other services.
