How to Choose a Mattress for Side Sleepers
Side sleepers need a mattress that cushions the shoulders and hips. Look for a medium-firm feel to balance pressure relief and support. Memory foam is a popular choice because it contours closely. Cooling features are important if you sleep hot. Consider your weight and sleeping position to determine the right firmness.
Understanding Mattress Firmness and Support
Firmness is subjective, but most side sleepers prefer a 6-7 out of 10. This provides enough sink for pressure points while keeping the spine aligned. Support refers to how well the mattress keeps your body from sinking too deeply. A high-density base foam adds durability and prevents sagging. Always check the mattress's weight capacity if you are heavier.
Specs that matter
| Type | Memory Foam |
| Thickness | 12 inches |
| Firmness | Medium-firm (6-7/10) |
| Layers | Gel-infused memory foam, transition foam, high-density base foam |
| Warranty | 10-year limited warranty |
| Trial | 100-night sleep trial |
You're a side sleeper seeking pressure relief and cooling without breaking the bank.
You need strong edge support or weigh over 230 pounds, as the foam may compress more.
Questions before you buy
Is the Sleep Innovations Marley good for side sleepers?
Yes, the Marley's memory foam conforms to the body, relieving pressure on hips and shoulders. Its medium-firm feel suits most side sleepers. However, heavier side sleepers might prefer a firmer option.
Does the Marley sleep cool?
The gel-infused memory foam layer helps draw heat away from the body. Many owners report it sleeps cooler than traditional memory foam. But if you're a very hot sleeper, consider a mattress with active cooling features.
What is the warranty on the Marley mattress?
The Marley comes with a 10-year limited warranty. It covers manufacturing defects and premature sagging. Be sure to read the terms for full details.
How long does the off-gassing smell last?
Most owners say the initial odor dissipates within a few days. Ventilating the room and allowing the mattress to air out helps. It's a common trait of foam mattresses.
Can I use the Marley on an adjustable base?
Yes, the Marley is flexible enough for adjustable bases. Its foam construction bends without damage. This allows you to elevate your head or feet for added comfort.
Does the Marley have good motion isolation?
Yes, memory foam excels at absorbing motion. Couples will appreciate that movement on one side doesn't disturb the other. This makes it a good choice for light sleepers.
Is the Marley suitable for stomach sleepers?
Stomach sleepers generally need a firmer mattress to prevent hip sink. The Marley's medium-firm feel may work for lighter stomach sleepers, but heavier ones might need more support.
What is the return policy?
The Marley includes a 100-night sleep trial. If you're not satisfied, you can return it for a refund. Check the retailer's specific return process for details.
