Upsizing a bed? Comfort questions.

We have a Cedar Creek 38CK with a queen memory foam type mattress. The mattress is just OK. It's not the most comfortable but it is far improved over our bed in our former house. It seems to be more firm than either of us like. We've considered adding a topper or even getting a thinner type inner spring mattress to put under it so we wouldn't feel like we are sleeping on foam over plywood (which we are).

On the flip side we are thinking that upgrading to a king mattress may be in order. We have two chubby fur babies that sleep with us. So more room would be appreciated. We've got the clearance on either side of the bed that would allow an upgrade on size. If we do this - how do we do this? Obviously the wood underneath would have to be made larger. Is that an easy thing to do?

Suggestions? Thoughts? All are much appreciated.

Queen mattress......60"W x 80"L (RV queen 60x75)

King mattress .......76"W x 80"L

You would have to widen plywood platform 16"--it would have to solid/supported for extra with and weight of king mattress

We got rid of the OEM full queen mattress in our 5th wheel and went with a Tuft & Needle Full Queen

Mattresses are so subjective....what works for one is terrible for others

I upgraded to a king from a queen- changing the plywood was not that big a deal. Got new mattress fron Denver Mattress, rv size. Works great.

The queen is a good size for us. To go any larger will take away from walking around space in the bedroom--wall to wall bed if a king is used.

Our fifth wheel came with a cheap pillow top mattress, and we added a 3" high quality memory foam topper and a nice mattress pad. We also found a factory outlet in Gatlinburg selling bamboo pillows cheap, and we now sleep just fine.

Almost all RV king size beds are 72" wide, a few have residential size that are 4" wider at 76". Most RV King sized beds are the following sizes.

RV King short 72" x 75"
RV King regular 72" x 80"
RV Cal King 72" x 84"
Eastern King 72" x 80"

Hope these measurements help you in deciding if you have room for it. Just remember if you do go with the king size, you are adding more weight to your rig with more wood and added weight of the mattress..

I put a SleepNumber mattress in our 5er. Regardless of the size, it really reduced the weight. Only too a couple of hours to install the pump and hoses.

When we ordered our current 5th wheel, we eliminated the mattress and provided our own. That way, you can shop and find the mattress that is right for you. I would say if you have under bed storage to be careful of the weight of your new mattress. We had to move the pistons so the bed would stay "up" when. Accessing the underfed storage. Weight is one of the reasons that foam mattresses are popular alternatives for RVs.
