The plush flocking on the top gives a more luxurious sleeping surface and helps to keep bedding from slipping. Dual chamber construction. The lower chamber functions as the box spring form of a traditional bed. Deflates completely for storage or travel. Please note: Stretching is a natural characteristic of new vinyl and the first few times you use the mattress, some stretching will occur suggesting that the mattress is losing air. It is simply stretching under your body weight and this is normal for the first few uses - it will not contine. Just add more air to the bed to counteract the stretching.
