Medium Breathable Mattresses | Airflow, Moisture‑Wicking & Fresh Sleep White Evergreen Mattresses

Medium mattresses balance cushioning and support — soft enough to relieve pressure, firm enough to keep your spine aligned. This medium-firm feel is the most universally comfortable choice, suiting combination sleepers, couples with different preferences, and most back and side sleepers. Compare every medium option below by brand and profile.
Breathable mattresses use open coil systems, ventilated foams, and airflow-promoting covers that let heat and moisture escape instead of building up — a natural fit for warm rooms. Compare every breathable option below by brand, type, and feel.

Evergreen offers natural and organic latex mattresses that combine eco-friendly materials with ergonomic design. Handmade in Canada, Evergreen beds use certified organic latex, cotton, and wool to deliver safe, comfortable, and supportive sleep for health-conscious Canadian shoppers.
