iComfort Mattresses Side Sleeper Temperature Regulating Yes All Mattresses

iComfort by Serta features advanced cooling foams and gel technology that draw heat away for a cooler night's sleep. Compare every option below by feel, size, and price.
Side sleepers need a mattress that cushions the shoulders and hips while keeping the spine aligned — usually a plush to medium feel with strong pressure relief and contouring. The options below help side sleepers avoid shoulder and hip pain. Compare them by brand, feel, and profile.
Temperature-regulating mattresses balance heat and airflow to hold a neutral, consistent sleep temperature through the night — not too hot, not too cold. They suit sleepers whose temperature swings. Compare every option below by brand, type, and feel.

Shop 200+ mattresses from Serta, Beautyrest, Sealy, Tempur-Pedic, Springwall, and Stearns & Foster at National Mattress — available in Single/Twin through King sizes from $99 to $6,640. Choose from innerspring, euro-top, memory foam, hybrid, and latex constructions in four firmness levels from extra firm to plush. Every mattress is manufactured in Canadian factories using CertiPUR-US® certified foams and ships free across Canada with a 365-night sleep trial, price match guarantee, and manufacturer warranty coverage up to 25 years.
