D.M.
I thought i had a soft bed and box frame but after it arrived
on one set it was hard and the other one a few days later was.
According to the contract we did not know at the time once we even looked at the set it was take or leave it no refunds.
So watch out and be ware of even known bed cos.
My dad had a chiropactor have a bed special made.
It lasted him 15 +/- yrs and out lived him by 5 yrs atleast.
good hunting.
Hint ask to see the springs and frames some co. take in old frames and reuse them.
