As humans, we spend roughly one third of our lives on earth sleeping. This should indicate that your mattress is about the most important piece of furniture in your home. However, according to research from Consumer Reports, 68% of Americans say they have difficulties getting a restful night of shut eye. Why do you think that is?

Research form the Sleep to Live Institute point out that many aspects of a mattress can impede a healthy night’s sleep. Aside from lumps, thin areas, and springs digging into your back while you snooze, sleeping well mostly comes down to being comfortable. For instance, the National Sleep Institute says that while back sleepers can sleep on just about any mattress, stomach sleepers require a mattress soft enough to lessen pressure on the back ribs while remaining rigid enough to keep the spine healthily aligned. Finally, most side sleepers snooze best on medium or soft mattresses.

So maybe it’s time to purchase a new mattress. But before you buy the first mattress you see from some pushy salespeople, consider the following most common mattresses for your slumber needs:

1. Pillow-top mattresses
Pillow-top mattresses offer an additional layer of padding in an extra layer of soft padding. Pillow tops are essentially giant feather- or down-filled pillows for your bed.

2. Foam mattresses
Foam mattresses come in many types and combinations made up of latex, memory foam, and polyurethane that are meant to be flexible and mould to the contours of your body. Specialty foam mattresses come in various thicknesses and flexes for many unique sleeping needs. For instance, while latex is usually recommended for those in need of firmer support (i.e., good for those with low back pain); memory foam is better for individuals who tend to be cold at night (it hugs in heat) or who suffer from chronic pain as it better molds and contours for different sleeping positions.

3. Hybrid mattresses
Hybrid mattresses combine the latex, polyurethane, or memory foam of a specialty mattress with the steel coils of a innerspring mattress to make a hybrid that’s big on firmness, flexibility, and contouring.

4. Adjustable mattresses
For patients with chronic pain, the pain can move and radiate in various parts of the body as you slumber. This is why an adjustable beds, as suggested in the name, can be lowered, raised, or elevated for comfort on a night to night basis. Many adjustable mattresses offer dual functionality for couples so each side can be adjusted separately.

5. Innerspring mattresses
Likely the most popular style of mattress among North Americans, innerspring mattresses consist of padding and hundreds to thousands of individual steel coils, which determine the soft to firm ration (more coils typically mean more firmness). Because of this range, lie on a innerspring mattress for longer than 5 minutes to get a true feel for its firmness.
