AirCell has an open-cell structure with billions of micro air capsules which magnifies all the awesome qualities of memory foam without all the heat capture or sagging that is associated with the more traditional memory foam.

Coming in at 3 firmness levels: soft, medium and firm, making the GravityLux is bed ideal for all types of sleepers.

What is Memory Foam?

Memory foam is a substance that was invented by NASA to help keep their astronauts safe from collisions and G-force. It’s made out of polyurethane combined with other substances that are designed to give memory foam its unique look and feel.

The market for memory foam mattresses is exploding in popularity due to its ability to mold and conform to your body shape while sleeping. The best thing about memory foam is that it bounces right back to its original shape once you take pressure off it, unlike traditional innerspring mattresses.

Nowadays, most mattress companies utilize an open cell technology on their memory foams due to the fact that the open cell structure allows more air to flow through as closed cell memory foams retain heat quickly.

Some companies have even developed their own proprietary memory foam alternatives such as non-viscoelastic memory foam and gel-infused memory foam.
