Innerspring mattress

This kind of mattress is one of the most commonly used around the world. The newer versions are found more durable than before because they are now supported by individually enclosed coil springs.

Air mattress

Air mattresses or air beds have long been used for patients with spinal cord injuries because they can easilybe adjusted. This type or mattress looks like a standard innerspring mattress, but instead of coils, it uses air-filled chambers. They are usually covered by a foam layer on top.

Some versions even allow you to split the inflation level of the two parts of the mattress to accommodate yours and your partnertion level ofs.
