Product Description
Built for sleepers who prefer substantial support, the Canadian-made UltraFlex® DYNASTY pairs high density foam with an extra firm feel and a streamlined tight top. Its cushioning helps distribute body weight, while breathable construction encourages airflow and low motion transfer reduces the movement felt across a shared bed. The tailored 9 inch profile gives your bedroom a clean, refined finish, bringing together firm support and everyday comfort in a mattress designed for those who know exactly how they like to sleep.
Key Features

A substantial foam feel for sleepers who prefer a firmer surface and a pronounced sense of support.
2. High density foam cushioning

An airflow oriented design supports a more comfortable sleeping environment without adding unnecessary bulk to the tight top.
4. Less movement across the bed
Low motion transfer helps reduce the spread of everyday movement when sharing your mattress.

I purchased the 3rd mattress from Ultraflex for my family, you can tell how I liked the first one!
Years ago I had a very firm mattress and loved it. Then I had to sleep on much softer and got back aches. I bought firm, it’s foam, how firm can it be? Really firm. I love it but I will have to get used to it. After 2 1/2 weeks I can see a good difference on my aches. Will buy again and recommend for sure.
