We have found a 2" foam mattress topper that we really like for the aft berth on our H26. It helps the hard spots quite a bit. It is made of the pressure/heat sensitive foam that conforms to your body but is not hot to sleep on. The package includes a mattress pad. We now have it on top of the stock cushions in Grizzly Bear (and also in the camper). You can find the "Q-structure topper 60x80" at domestications.com for around $160 delivered. Here's to sound sleeping, Jim
