Designed for tall sleepers, this Twin Xl air mattress measures 80"" x 39"" x 18"", offering 5"" more length than a standard twin for full support and comfort. It features a luxury pillow-top with a soft, velvety flocked surface and a honeycomb pillar design with 21 air coils for even weight distribution and natural body alignment. Made with durable 0.4mm puncture-resistant Pvc and a reinforced dual-stitched frame, it supports up to 500 lbs without sagging. The mattress passes a 48-hour leak test and includes a patch kit for quick repairs. Inflate in 2 minutes with the built-in 120V pump deflates easily and stores in the included carry bag. Slight expansion occurs in the first 2-3 days after inflation, which is normal. Perfect for home, camping, dorms, and guests.
