Buying Just A Mattress -

: A high-quality mattress should remain sturdy and not bend excessively when lifted from one side. 3. Shopping and Protection

: Ensure your current bed frame or "cot" is compatible with the new mattress. For example, memory foam mattresses often require a solid foundation or a platform bed rather than a traditional box spring to prevent sagging .

: Verify dimensions carefully, especially for specialty items like crib mattresses , as even small gaps between the mattress and frame can be unsafe.
