There isn't another mattress topper in Canada that is anything like the Principle.

We've created a high-performance, highly-elastic mattress topper by utilizing 2.5" of pure high-resiliency (HR) Smart Foam. The result is an exceptional level of comfort and durability at a modest price.

To ensure the most breathable experience, we do recommend the St Dormeir mattress protector from St Geneve. This machine-washable wool-lined mattress protector will balance temperature and humidity better than virtually any other solution available. If your existing mattress is in good condition and is simply a bit too firm and you're also finding it sleeps hot, the combination of the MLILY Principle topper and St Dormeir mattress protector will absolutely transform how you sleep.

General Availability Advice

The Mattress & Sleep Company is a family owned and operated Canadian retailer. We specialize in high-quality bedding, bath and mattresses from Canada, Europe and the USA. Our vast selection makes it impossible to stock everything. For this reason, our website does not offer real-time inventory availability as many of our products are made to order.

Please read the availability details above as we do make an effort to draw attention to products which are typically in stock in our Calgary, Edmonton and Sherwood Park stores and warehouses.

For time-sensitive needs, please give us a call Toll-Free on 1 (877) 750-1212 or Send us a Message and we will be delighted to help.
