Get a truly comfortable sleep at a comfortable price with a Serta Perfect Sleeper Hybrid Keynote Firm Mattress. This mattress is proudly designed and built in Canada.

Designed with input from the National Sleep Foundation, the Serta Perfect Sleeper series helps to address 5 common sleep problems.

  1. Tossing and Turning
  2. Lack of Support
  3. Sleeping Too Hot or Too Cold
  4. Partner Disturbances
  5. Mattress Roll-Off & Sagging

The Serta Perfect Sleeper Hybrid Keynote Firm Mattress is suitable for front and back sleepers who have a preference for a firm mattress. The quilt and upholstery helps with cooling since it integrates Serta’s Cool Twist Gel Infused Memory Foam, Cool Action Gel Memory Foam, and Serta Support Foam. Pressure relief is thanks to the Perfect Response Latex. Additionally, the advanced technology used in the making of this mattress, helps improve the overall quality of your sleep. As well, this mattress has a lumbar support core.

The mattress absorbs motion easily, causing little to no disruption by a partners movement. Please note that for the first night, you may notice a slight “new mattress” smell.

Rotating your mattress from head to foot once a year helps to prevent wear. No flip.

    We couldn’t be more thrilled to be sleeping on our new mattress. We absolutely love it. I feel like we should’ve made this investment earlier.

  2. 5 out of 5


    We’ve been to so many mattress stores and tried more than 20 mattresses, this is the best for us. Firm, supportive, good contouring and cool. I also recommend it to my nephew and he is very happy with the mattress.
