“Thank you! I have a hand-carved rosewood sleigh bed, purchased last year. Although it has a center beam, my box springs just do not seat on it evenly. I have been searching for the right mattress supports before purchasing a new mattress for myself. As unbelievable as it may seem, employees at the mattress stores haven’t a clue when I inquired about supports.I was thrilled to find your supports. My bed has a ledge on the side rails (to support box springs), so your supports should work well. I am thrilled.
