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 (8-9 on a 10-point firmness scale) to prevent excessive hip sinking. This helps alleviate lower back strain and promotes better spinal alignment.

Medium (5-7/10)

Combo Sleepers

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.

130-230 lbs

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.

Shop 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.

"Amazing service"

Amazing service. I contacted them as my pillow case zip had broken. I wanted to buy a replacement cover for it but they don’t unfortunately sell separate pillow cases. The person that emailed me was very professional and caring and offered me a free pillow as a gesture of goodwill. I didn’t expect that, I only wanted a replacement cover which I would have paid for. Thank you very much. Without delay the new pillow has already arrived. Please do a line of replacement covers though, you are letting yourself down as your pillows are the best x

Great Experience! Fast Delivery! The bed actually impressed me. I have severe spinal damage and for many years I slept at the 100 setting on a Sleep Number bed.

Frequently Asked Questions

When should I buy a new mattress?

You may need a new mattress if your current one shows visible sagging, has permanent body impressions exceeding 1–2 inches, or no longer provides comfortable support. Consider upgrading if you frequently wake up with back, neck, or shoulder pain, have recently moved to a new home, are sharing a bed, or simply desire improved sleep quality.

Select your mattress size based on your room dimensions, sleepers' heights, and the number of users. A Twin mattress is ideal for a single sleeper in a smaller room. A Full mattress accommodates one or two sleepers, while a Queen is a popular choice for couples. A King provides ample space for two or more sleepers, and a California King is perfect for taller individuals.

Queen and King mattresses are ideal choices for couples. A Queen mattress provides a comfortable fit for two sleepers and is well-suited for a 10' x 10' room. In contrast, a King mattress offers more personal space, making it better for larger rooms, typically around 12' x 12'.

Side sleepers typically require a softer mattress that provides adequate cushioning for the shoulders and hips. A plush-to-medium mattress (3-5/10) can effectively alleviate pressure points while ensuring proper spinal alignment throughout the night.

Back sleepers typically benefit from a medium-firm mattress, rated between 5 and 7 on a 10-point firmness scale. This level of firmness provides optimal spinal support while offering adequate cushioning for the shoulders, hips, and lower back.

Stomach sleepers typically require a firm to extra-firm mattress to prevent excessive hip sinkage. A firmer surface alleviates lower back strain and promotes better spinal alignment.

A hybrid mattress combined foam comfort layers with supportive coils is a strong choice for many sleepers. This design can offer breathability, responsiveness, pressure relief, and stable support, making it suitable for a wide range of sleep styles.

Memory foam is helpful for pressure relief and motion isolation, which can benefit couples who are easily disturbed by movement. Hybrid mattresses can also work well for couples because they combine foam comfort with coil support, better airflow, and a more responsive feel.

Focus on the features that solve your specific sleep problems. Important mattress features include support and spinal alignment, pressure-relieving comfort layers, temperature control, motion isolation, edge support, and hypoallergenic or certified materials.

Hot sleepers should look for mattresses with temperature-control features such as breathable coils, open-cell foam, gel-infused memory foam, Tencel™, phase-change materials, or latex. COOLING COLLECTION Cooling Hybrid mattresses are often a good option because the coil layer improves airflow.
