OP mattress’s may not be old, think of how many mattress come from soft to hard as a rock.
We bought mattress for our preference, would have no idea how one would please thousands of renters.

Our parents used our brand new 1week old home, with all new furniture. (We loved our furniture, as did our home watch person) My parents hated the mattress in the master, but tolerated the guest room. They hated the lounge chair, couch, and loveseat. Loved the dining set, but not the kitchen set. Tolerated the top of the line cookware. Hated the pepper grinder (can’t you just buy a pepper shaker)

I got weekly sometime daily grumbling. They absolutely hated the golf cart, because it didn’t have the hard enclosure.

I would remind them…You are staying at our home for 5.5 months for FREE.
