A proper foundation is essential for mattress support, longevity, and warranty compliance.
For memory foam and latex mattresses, solid or slatted platforms work best. Slats should be no more than 3 inches apart.
Innerspring and hybrid mattresses often work well with box springs, which add height and some give to the sleep surface.
Adjustable bases offer the most versatility, allowing you to elevate your head or feet for better comfort.
Consider the height you want your bed to be, your room aesthetic, and any storage needs when choosing.
Warranty compliance is often overlooked when choosing a foundation. Many mattress warranties require specific foundation types — using the wrong one can void your warranty entirely. Always check your mattress manufacturer's foundation requirements before purchasing.
Adjustable bases have grown from niche products to mainstream options, with prices starting under $300. They allow head and foot elevation for reading, reduced snoring, and improved circulation. Most hybrid and foam mattresses work well with adjustable bases.
DIY platform beds with slats are increasingly popular. If building your own, ensure slats are no more than 3 inches apart for foam mattresses (tighter for softer foams) and use 0.75-inch thick solid wood or metal slats for adequate support.
