Span America Geo-Mattress Atlas Bariatric Foam Mattress
Model: Geo-Mattress Atlas (10 sizes, 35–54″ wide)
Availability: In Stock – Ready to Ship
A 7-Inch, Four-Layer Bariatric Foam Mattress Rated up to 750 lbs
The Span America Geo-Mattress Atlas is a non-powered bariatric foam mattress built for heavier users. It uses four layers of foam with progressive resistance: three high-resiliency support layers that get firmer toward the base, topped by a 2-inch Geo-Matt layer of more than 800 independent cells that move with the body to help redistribute pressure. Ring-of-Air channels between the cells help carry heat and moisture away from the surface, and a tapered heel slope at the foot end is designed to shift load from the heels onto the lower legs.
The Atlas is 7 inches high at the centre and comes in ten sizes, from 35 to 54 inches wide and 75 to 84 inches long. Weight capacity depends on width: 600 lbs for 35-inch sizes, 675 lbs for 39-inch, and 750 lbs for 42, 48 and 54-inch sizes. The cover is fluid-proof, bacteriostatically treated coated nylon that wipes clean, and the mattress fully articulates on a standard hospital bed frame. It weighs about 36 lbs on average.

Equipment Specialist Insight: Pick the width first, by the user’s weight and the bed: 35″ sizes are rated to 600 lbs, 39″ to 675 lbs, and 42″, 48″ and 54″ to 750 lbs. Then match the length and width to the bed deck so the mattress fills it with no large gaps. Wider sizes need a bariatric bed frame of the same width, and the bed itself must be rated for the combined weight of the user and mattress — check the bed’s safe working load before ordering. Clean the cover with neutral soap and lukewarm water or a hospital-grade disinfectant, let it air dry, and never put a wet cover back on the foam.
