I am a fulltimer in a 30ft. Class “C” motor home. It came with a built in solid platform short Qn. bed that i was using an air bed/mattress on. It isn’t working 
so I am actively looking to replace it ASAP since the air bladder has [for the fifth time] developed a serious leak.
There is no room for any thing other than the actual mattress–preferably @ 8/9 inches deep. I am a combo sleeper, side mostly then some stomach, rarely back. 5’5", 210lbs. and I sleep alone, except occasionally w/my Dober gal, Junah.
I need something not TOO heavy or hard to move as room to make the bed or apply bedding is…tight?
I am familiar with latex, and after reading your excellent informational articles, I think I need a 2 1/2 to 3 in. comfort layer, with a combo innerspring w/a latex core or layer.
I can’t stand memory foam–too soft, too hot for me. I prefer natural materials, and have no love of polyfoam.
I am currently parked in Glendale, AZ. for the next three weeks and will be looking to purchase the “perfect” short RV Qn.
Can you point me at manufacturers in this area ? The list is HUGE here, and being able to narrow down the options would be greatly appreciated! Thanks!
