- Firmness is influenced by location, temperature, and humidity. The airbed may need occasional re-inflation to maintain the desired firmness when used for more than a few days, as vinyl tends to relax over time. - Measurements vary with inflation. The size is measured from the widest point including side beams and bulges, and from the floor to the tallest point including any built-in pillows if applicable. - Full-size inflatable mattress with a 20.8-gauge waterproof flocked top. - Flocked surface is soft and comfortable, and helps keep bedding from sliding off. - Sturdy construction with 14-gauge vinyl beams and a 15-gauge bottom for durable support. - 2-in-1 valve with extra-wide openings for fast and easy inflation and deflation. Key benefits and practical considerations: - Comfortable sleep surface with a soft, non-slip top that helps keep sheets in place. - Durable, reinforced beams and bottom provide reliable support for longer-term use. - Quick setup and breakdown through the wide 2-in-1 valve.
