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. Featuring a luxury pillow-top with soft, velvety 0.2mm flocked fabric and a durable 0.4mm puncture-resistant Pvc, it balances comfort and toughness. The honeycomb pillar design with 21 air coils evenly distributes body weight to prevent sagging and maintain natural alignment. With a reinforced dual-stitched frame tested over 1,000 cycles, it supports up to 500 lbs without drooping. Each mattress passes a 48-hour leak test and includes a patch kit. Inflate in 2 minutes with the built-in 120V pump. Slight expansion in firmness occurs over 2-3 days, which is normal. Perfect for home, camping, dorms, and guests.
