need help choosing bunk bed mattress...foam rubber??

I ordered from The Form Factory. Reviewed them here:

For bunkbeds, I added 4" Lux-R Foam mattresses and use that in addition to the crappy "mattresses" that came with the camper.

Purchasing foam rubber is frighteningly expensive--even online.

I suggest buying 4" memory foam mattress topper. It's best cut to size with an electric knife out of your kitchen.

Our new fifth wheel trailer came with a "rock" of a queen size pillow top bed. We added a 3" memory foam topper, and it sleeps great.

We added a 4" memory foam mattress top onto our existing (crappy) mattress. $125.00 or so from Wal-Mart, and heavenly. Might work on a bare platform as well, not sure. Might have to try that.

I have ordered through a large foam place. I found it best to go to their showroom as they had display beds to lay on. The first 6 in piece we bought was too firm so we added a 2 in thick piece of cheaper egg crate style foam. Now it has more of a pillow top feel to it.


One example

I bought mine at an upholstery supply distributor. There should be one in a big city close to you. Shipping foam can get spendy.
