3 Value Priced Memory Foam Beds with King Bed Dimensions

Maniac's Tip: Let all compressed memory foam mattresses expand at least 24 hours before you sleep on them - no less. Most manufacturers recommend 48 hours. Your new bed may look fully expanded in an hour or so, but you can't see the microscopic cell expension that hasn't taken place yet. Your visco memory foam mattress will last longer and sag less if you stay off it for at least a full day. Two is better.
