The plush, soft surface and integrated pillow take the deluxe version of our Pillow Rest Raised Bed to another level of luxury, making it a premium sleeping experience with extra head support. The Deluxe Pillow Rest adds a sturdier outer layer, making it even more stable and comfortable than the original. It is equipped with a quality-tested, 21.2-gauge waterproof flocked top, along with 15-gauge vinyl beams and 16-gauge sides and bottom. The resulting surface is comfortable and secure, whether you're sleeping at the in-laws' overcrowded house or setting up a guest bed in the basement. In addition, the Deluxe Pillow Rest is remarkably easy to inflate thanks to the built-in, high-powered electric pump, which does its job in a mere two minutes. No more fussing with tiring hand or foot pumps or rummaging through the garage for your detached electric pump. And should the mattress feel a little too soft or firm, you can customize the comfort level with the touch of a button. The Deluxe Pillow Rest is raised 18 inches from the floor, making it far taller than most inflatable mattresses, and includes built-in pillows for added comfort. At 39 by 16 3/4 by 75 inches (W x H x L), the mattress is an official twin size, making it a good fit for fitted sheets. The Deluxe Pillow Rest Twin bed--which offers a capacity of 300 pounds--comes with an AC power cord, a shoulder strap, and a carry bag. Regarding Inflation: Measurements will vary based on the manner in which it is inflated and packaging disclaims approximate size. Airbeds are measured from the widest point including the beams (bulges) on the side and off the tallest point from the floor including built-in pillows if applicable. Location, temperature, and humidity will affect the airbeds firmness. Airbeds will need to be occasionally re-inflated (topped off) to maintain desired firmness when used for more than a few days as vinyl tends to relax over time.
