Memory Foam
If you are looking for good support and comfort, memory foam is a brilliant choice. Memory foam is liked because of the way it slowly conforms to your body as you sleep. If you sleep on your side, it supports your shoulder and hip.
Other advantages of memory foam mattresses are that they have several layers of foam that resist the tendency to sag in the middle.
Gel
In smart gel mattresses, gel is generally added to a foam mattress in the support system or upholstery layer. It has a slightly different feel than memory foam. Gel mattresses also dissipate your body heat more efficiently, so if you don’t like the way some foam mattresses absorb your body heat, smart gel mattresses are for you.
Pillow Tops
Pillow tops are essentially an additional layer of upholstery that is added to the top of your mattress. They are very soft and cushiony. Hence, allow a similar “sinking” feeling as memory foam. You get to choose the level of softness for your pillow top. They are usually used with an innerspring or coil mattress.
Innerspring
Innerspring (also, coil) mattresses use the support of metal springs. You can normally know the quality of support from an innerspring mattress by seeing how many coils are there in the design. The number and distribution of coils will tell you how well the mattress will conform to your body. These mattresses are comfortable for people who sleep on their back, side, and tummy.
Air Bed
An air bed uses a chamber filled with air as the main support. It is packed with foam or fiber upholstery. The air chamber is adjustable. This allows you to adjust and modify the firmness of the mattress. A few brands allow you to adjust each side of the mattress separately. Air beds are great for couples with different firmness needs.
Latex Mattresses
Latex mattresses use latex foam in place of memory foam. Latex also offers varying levels of firmness. Latex is not as dense as memory foam.
Adjustable Bases
Adjustable base mattresses are the most flexible kind of mattresses. They offer relief and support wherever you require it. You can adjust the base to raise your head, elevate your feet, or get more back support. They are great for sleep-related issues such as muscle aches, back pain, acid reflux, heartburn, sleep apnea etc.
