How to Choose the Right Mattress for Side Sleeping

Side sleepers need a mattress that cushions the shoulders and hips while keeping the spine in neutral alignment. A surface that is too firm creates pressure points at the shoulder and hip, while one that is too soft allows the midsection to sag. Most sleep specialists recommend a medium to plush firmness for side sleepers, soft enough to let the shoulder sink in, yet supportive enough to maintain spinal alignment from neck to tailbone.

Construction type matters as much as firmness. Eurotop and pillowtop mattresses, which make up 55% of our side sleeper collection, add a sewn-in comfort layer that contours around pressure points without the slow-response feel of foam. Memory foam models offer deeper conforming for targeted pressure point relief, while hybrid mattresses combine pocket-coil support with foam comfort layers for sleepers who want contouring plus airflow. The side sleeper mattresses at National Mattress are manufactured in Canadian factories 🍁 and carry CertiPUR-US® certified foams.

Frequently Asked Questions About Side Sleeper Mattresses

What firmness is best for side sleepers?
Medium to plush firmness is ideal for most side sleepers. These comfort levels allow the shoulder and hip to sink in enough to maintain neutral spinal alignment while preventing pressure buildup. Lighter-weight side sleepers may prefer plush, while heavier sleepers often do better with medium.
Which mattress type relieves shoulder and hip pain for side sleepers?
Eurotop/pillowtop and memory foam mattresses provide the deepest contouring for side sleeper pressure points. Pillowtops add an integrated comfort layer that cushions immediately, while memory foam moulds gradually to your body shape. Both can reduce shoulder and hip tension significantly.
Can side sleepers use an adjustable base?
Yes, 97% of the side sleeper mattresses at National Mattress are compatible with adjustable bases. Elevating the head 10–15° or raising the knees slightly can reduce spinal pressure and improve circulation while side sleeping.
What sizes are available in side sleeper mattresses?
National Mattress carries side sleeper mattresses in Single/Twin, Twin XL, Double/Full, Queen, King, and RV Short Queen sizes. Compare current prices on the product page for the size, brand and construction you prefer. All sizes ship with free express delivery across Canada.
How do I choose between a pillowtop and memory foam mattress for side sleeping?
Pillowtops offer immediate cushioning with a traditional spring-supported feel, ideal if you change positions at night. Memory foam conforms more closely and excels at targeted pressure relief, but responds more slowly. Hot sleepers may prefer a hybrid that combines foam contouring with coil airflow.
Does National Mattress offer a sleep trial on side sleeper mattresses?
Before choosing a mattress, read the sleep trial terms. Review the manufacturer warranty information for the model you prefer, and consult the price match policy when comparing offers.
