3 Inch Heavy Duty Low Profile King Box Spring - Noise Free Metal Bed Base with Fabric Cover, Easy Assembly Mattress Foundation for King Size Beds | Perfect for Guest Rooms, Master Bedrooms & Apartment Living

Our bed is a platform bed with both sideboards and a footboard. Due to the thickness of the mattress, even when we tried to use a 5” boxspring, the top height of the mattress was way too high and it was difficult to get into the bed. However, when we placed the mattress directly on top of the bed frame slats, the mattress actually sat down in the platform bed, about 2” below the side and footboards making it very difficult to lift the mattress to make the bed. This product accomplished our goal of raising the mattress up just enough to clear the side and footboards, but not making the height of the top of the mattress too high. It raised thebottom of the mattress about 1 inch above the side and footboards . Now, it is so much easier to get underneath the mattress when making the bed. Assembly was very easy. I took my time, was very careful and it took about 45 minutes to assemble. The instructions have excellent illustrations that clearly illustrate the assembly process. This unit is very sturdy and is exactly as described by the manufacturer. Again, mission accomplished!
