Sleep Positions and Firmness

Selecting the right level of firmness in a mattress is essential for achieving healthy sleep. A wise approach is to choose base on your usual sleeping position:

Plush(3-5/10)

Side Sleeper

Plush Memory Foam Mattress

Pressure relief for side sleepers

The side-sleeping position requires a mattress that offers adequate cushioning for the shoulders and hips to prevent pressure points. Choose a plush memory foam mattress that contours to your lumbar region. ensuring your spine remains properly aligned throughout the night.

Medium(6-7/10)

Back Sleeper

Medium Firm Hybrid Mattress

Spinal alignment for back sleepers

A medium-firm mattress (rated 5–7 on a 10-point firmness scale) is optimal for most back sleepers. It strikes a balance between support and pressure relief and promotes neutral spinal alignment while cushioning the shoulders and hips.

Extra firm(8-9/10)

Stomach Sleeper

Firm Innerspring Mattress

Firm support for stomach sleepers

Stomach sleepers require a firm to extra-firm mattress (6–8 on a 10-point firmness scale) to prevent excessive hip sinking. This helps alleviate lower back strain and promotes better spinal alignment.

Extra firm(5-7/10)

Combo Sleeper

Balanced Latex Mattress

Organic latex mattress for combo sleepers

A medium-firm mattress is generally the best option for combo sleepers who switch between sleeping positions throughout the night. Hybrid and latex mattresses offer a balance of support and pressure relief that can accommodate multiple sleeping positions.

Mattress Firmness by Body Weight

Your body weight plays an important role in determining the ideal mattress firmness.

6 Key Features to
Look for in a New Mattress

You don’t need every feature – prioritize the ones that solve your personal sleep problems.

01

Support & Alignment

Proper spinal alignment is essential for preventing pain and discomfort. Choose a zoned support mattress that offers firmer support under your hips and softer cushioning at your shoulders, or consider high-density foam cores.

02

Comfort Layers

Pressure-relief mattresses are designed to alleviate pressure points through ergonomic curves that cushion your shoulders, hips, and lower back. Memory foam and natural latex mattresses provide the best pressure relief for side sleepers.

03

Temperature Control

Consider gel-infused memory foam, open-cell foam, natural latex, or hybrid coil mattresses that enhance air circulation. A cooling mattress featuring gel infusions, Tencel™, or phase-change materials is particularly suited for hot sleepers.

04

Motion Isolation

For couples, a motion isolation mattress is ideal. Memory foam mattresses excel at minimizing motion transfer from a partner’s movements, while hybrid mattresses with individually wrapped coils also perform well in this regard.

05

Edge Support

Mattresses with superior edge support maximize sleep surface area, enabling you to sleep or sit near the edge without the risk of rolling off. Hybrid mattresses with edge support typically outperform traditional memory foam mattresses.

06

Hypoallergenic

A certified organic mattress offers natural bounce, cooling properties, and eco-friendliness. Choose mattresses made with natural latex, organic cotton covers, and CertiPUR-US or GREENGUARD Gold-certified foam. Perfect for allergy sufferers.

Considers Before Purchasing a Mattress

To ensure your investment in a new mattress is worthwhile, keep these considerations in mind.

365-Night Sleep Trial

Testing a mattress in your own home is essential, as the only way to determine its comfort is by using it night after night. Consider a brand with a 365-night home trial policy.

365-night trial mattress

Worry-Free Guarantee

It’s important to read what’s covered in the warranty policy. You'll also want to consider how long a company guarantees its mattress's lifespan. A 10-year limited warranty is industry standard.
