Bed Frame Grey Mattresses Sealy® Mattresses and Accessories

These mattresses feature a grey or neutral-tone cover — and since that cover sits under your sheets, colour won't change how you sleep. To find the right bed, shop by size (twin to king), comfort (plush, medium, firm), or type (memory foam, hybrid, pocket coil). Every mattress includes a 365-night sleep trial and free delivery across Canada.

Sealy is a pioneering mattress brand known for its science-backed support and comfort. It was voted the #1 most trusted mattress brand in Canada, reflecting over a century of quality craftsmanship.

Shop 20+ Sealy mattresses across six collections — Essentials, Cocoon™, Posturepedic®, Posturepedic® Plus, Posturepedic® Luxury and Posturepedic® Natural Origins — in single/twin through king. Every Sealy we carry is made in Canada with a 5- or 10-year manufacturer warranty, plus our 365-night sleep trial and price-match guarantee.
