Boxspring Bedding/Sheets Springwall® Kingsdown® Mattresses for Standard Bed Frames All

Springwall is a proudly Canadian-made brand known for chiropractic-minded support and durable, value-driven construction. Compare every option below by feel, size, and price.

Kingsdown has been handcrafting premium sleep products since 1904, pairing over a century of craftsmanship with sleep-science-driven design. Explore Kingsdown's eco-conscious Dream Green collection in firm and plush comfort levels at National Mattress.


These mattresses are built for a standard bed frame, box spring or platform bed rather than an adjustable base — solid, no-flex support for a classic setup. Shopping by feel or build instead? Browse by comfort (plush, medium, firm) or by type (memory foam, hybrid, pocket coil, traditional). Using an adjustable base? See our adjustable-bed-compatible mattresses. Every order includes a 365-night sleep trial and free delivery across Canada.
