This worked pretty well but it seems pricy for a piece of foam

Answer:

This specialized material has to be laser shaved for the different thicknesses while leaving the natural skin for added rigidity. It’s then laser cut again in cutting patterns for size.  The manufacturing process also requires heat fusing to make the 1.5” thickness. Then, there is the cost of Amazon for processing orders and returns, warehousing, promotional costs and super-fast shipping. This is a DIY solution where we include the patented product, the directions and instructions and the know how to use this solution with technical support, not by a call center, but by the people that have dealt with this issue for decades. You simply have to weigh the cost-to-benefit to decide if this solution is right for you and how much it could save you by delaying buying new furniture or mattresses.
