Michigan Discount Mattress

Custom Size Low Profile Foundation (5.5″)

Best for: Low profile for odd sizes

The same made-to-order wood foundation at 5.5″ tall, for keeping a thick Olympic queen, RV or 3/4 mattress lower.

Good to know: Not returnable once made; measure the bed opening, not just the old mattress.
