Buying a Mattress in Markham: What You Should Know

Markham is home to over 350,000 residents and one of the fastest-growing cities in York Region. Whether you're furnishing a heritage home in Unionville, upgrading a condo near the Markham GO station, or setting up a new build in Cornell or Berczy, National Mattress carries the full range of sizes, firmness levels, and price points to match your space. Queen mattresses remain the most popular choice, but King mattresses are increasingly popular in the larger master bedrooms found in Angus Glen, Wismer, and Cachet.

Our Markham showroom is right on Woodbine Ave, easily accessible from Highway 7, Highway 404, and Major Mackenzie Drive. Families in the Milliken area are about 10 minutes south along Kennedy Road, while Thornhill residents can reach the showroom in roughly 15 minutes via Highway 7 East. With 19 brands in stock — including Sealy, Beautyrest, Tempur-Pedic, and Stearns & Foster — Markham shoppers don't need to settle for the limited selection at big-box retailers. Most of our models are 100% Canadian-made, and our 365-night sleep trial is the longest in the country (compared to 100 nights at Sleep Country).

Not sure where to start? Our mattress buying guide walks you through firmness, materials, and sizing. For side sleepers dealing with hip or shoulder pressure, our top-rated side sleeper mattresses are a strong starting point. And with wholesale pricing that saves 20–50% over traditional retail, plus a price match guarantee, every mattress purchase at National Mattress is backed by both value and confidence.
