When you need a bed in an instant, the Second Avenue Collection Classic Double Twin air mattress is perfect solution! No longer will your guests need to sleep on your sofa or the floor! Spend more time relaxing or sleeping and less time setting up. This extra soft yet durable double air bed provides a uniform and comfortable sleeping surface. It is designed with a plush rayon-flocked top to create a luxurious sleeping surface and to help keep bedding from slipping. The flocked sleeping surface is stain-resistant, waterproof and easy-to-clean with mild soap and a damp cloth. Its wave beam and sturdy, heavy-gauge vinyl PVC construction will help your air bed last for years. Location, temperature, and humidity will affect the air bed’s firmness. It will need to be occasionally re-inflated (topped off) to maintain desired firmness as vinyl tends to relax over time. Measurements will vary based on customer’s inflation.
