real mattress

We pulled out the full size queen from our new rig, and put our Sleep Number in. Not a hard job even with the air lines and pump. Just have to remember to deflate the cells when we start going to high altitudes.

Replacing the standard el-cheapo mattress is one of the easiest upgrades you can do.

Mine came with a Serta RV mattress which we find to be quite adequate. Just prior to the last trip we added a 1.5" memory foam topper that was on sale at Kohls and that made the sleep even better. The topper gives a nice initial cushion before the extra firmness of the Serta kicks in. Any better sleep and we'd likely not want to get out of bed and do anything!

OldBiscuit - adding that Tempurpedic must have put a significant dent in your cargo caring capacity. Those things are heavy.

The very first thing we did when we got our new 5'er was to take the nasty mattress out of it and replace it with a memory foam mattress that we got from Walmart. We have a Tempurpedic in our house and loved it. Figured we couldn't/wouldn't spent quite that much on a mattress for the RV. Ordered the Spa Sensations 8" memory foam for $200 online, had it in 2 days and unboxed in the bedroom of the RV. (This is a must because it's small until it encounters air and then it is heavy and bulky).

It sleeps as good, if not better, than our mattress at home. Lots of people complain that it is like a chunk of stone if it's cold, but I don't do cold weather camping without heat!!! If it's above 50 degrees, it's fine. The one that we purchased had a cover on it that allowed the foam to breathe and not get too hot. For $200 for a queen size and $300 for the king, when our Tempurpedic dies, we will replace it with the one from Walmart for 1/10 the price.

On edit: The memory foam mattresses require a solid platform, so you don't need, nor do you want a box springs with it.

Here is the one that we purchased - it's gone up a few dollars and is now $219.

Memory Foam Mattress

We had a fifth wheel with a East/West bed in a slide. Bought a House size queen and no box springs. It was a little tall, but not too bad, and we loved it.
It did push on the cabinet a little when closed, but no problem.

Our trailer came with a double but was sized for a queen so I picked up a 5" conventional foam from http://www.thefoamfactory.com
I know a number of other folks that have bought from them and been happy. I bought a firm and in retrospect the regular would have been fine.

To the OP, go for it! No need for box springs since I'm assuming that you're mounting on a piece of plywood or one of those fiber stretched- supports. I'm thinking about replacing my new Serta Mattress but it will be a job getting it out of my trailer!! LOL

We yanked the OEM queen out of our 5vr and replaced it with a full size queen tempur-pedic......

Nothing says you have to sleep on those cheap rv mattresses
