A mattress has a cover sewn over a cushioned non-absorbent core and is suitable for use as a resting place or sleeping space. The core is made of a netted material having a plurality of tangled, partially bonded filaments. The cushions can have various densities separated by baffles inside the cover. The cover can have a built in or added back support system. The mattress is a self contained carry case and needs no additional carry bag. A detachable shoulder strap doubles to carry the mattress and as adjustable straps to adjust the back support system. The cushion is manufactured in various sizes for standard outdoor camping as well as sizes for standard indoor bedding.
