The Swimline Roll-Up Mattress is cushy and cozy, and gives you a great floating experience around the pool or lake. Its ribbed surface adds to the level of comfort, as it gently supports your legs, neck, and back. The Roll-Up Mattress is made of attractive, yet durable vinyl with radio frequency (RF) welded seams, that will keep you relaxed and in style, season after season. The included mesh storage bag makes the mattress a cinch to roll up and carry along, wherever the sun, and water take you. You can also use the Roll-Up Mattress for stretching out on the side of the pool or on the shore of the lake. Inflation and deflation is easy with the simple stem valve. The roll up feature allows you to get going quickly, when you’re ready to head home. Inflatable air mattress measures (L x W) 182.9 cm x 81.3 cm.
