Recommended Support for MLILY Mattresses

Any firm, flat, level surface or electric adjustable bed. So long as your box spring isn't sagging, it will work just fine with your MLILY mattress. If you're planning to use this mattress on a platform style bed simply ensure your platform has sufficient support such as a solid surface or slats no more than 3" apart. Bowed/curved slats are fine!

Boxspring Dimensions

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.
