Try the Sleep Number. Lay on it in the store and adjust to preferred setting. Nothing like it. If too pricey, you can also find them on Craigslist...I so wish you were closer.

Go to Lowe's or Home Depot and ask for a 4x8' sheet of 23/32" OSB or plywood. Measure the length of your mattress, they'll cut it free of charge. It should be centered in between mattress and box spring or platform. Make sure your bed frame has a center support as well!
