This Dream Series inflatable mattress incorporates ComfortCoil technology and a SureGrip bottom design, ensuring stability and firmness, and bidding farewell to sliding and shifting. The built-in air coils not only enhance durability but also provide additional support, keeping the mattress flat and firm at all times. Equipped with a one-click internal pump, it allows for quick and easy inflation and deflation. Designed specifically for in-home and camping use, this mattress can be fully inflated in less than 4 minutes and will remain inflated for days. If you prefer a firmer sleeping surface, simply operate the pump to quickly add more air pressure. As an upgraded "double-height" inflatable bed, it features a unique dual-chamber design with inflated dimensions of 76"x56"x19". The top of the mattress is made of extra-thick waterproof flocked fabric, delivering a delicate touch and comfortable sleeping experience. Meanwhile, the multilayer, puncture-resistant eco-friendly PVC material further enhances the mattress's durability and lifespan, ensuring peace of mind with every use. Guests, friends, and relatives of all shapes and sizes will enjoy ultimate comfort on this mattress. Material: Plastic.
