If you decide not to put the mattress directly on the floor, we recommend a newer, modern rigid foundation. Many more recent box springs are designed with closely-spaced slats and provide more direct support to counter your body weight pushing down. Older box springs that were designed for spring mattresses, usually have one supporting beam down the middle of the bed, making the mattress sag on the sides. We also do not recommend split box springs, which can cause sagging.
The PERFECT PRESSURE mattress can work with all standard foundations; however, you want as much direct support under the mattress as possible. Unless you are putting the mattress directly on the floor, we recommend a newer, modern rigid foundation. Platform beds offer the most support. A slatted base with gaps between the slats, should be less than three inches apart. Platform beds offers the most support Most likely, you can use your existing bed setup.
No. You can turn the mattress 180 degrees while keeping the sleep-side up, but NEVER flip it. The Perfect Pressure mattress is bi-directional which means you can install it with either end at the head of the bed.
