I use my CPAP machine in a Pleasureway Excel. Explanation will make more sense if you look at this floorplan.

If we are hooked up to electricity I plug it into an outlet below the kitchen counter at the far right hand side when facing counter. There is also an outlet at the middle front of the couch below the seating.
With the couch bed you can make it up as a king size or leave out some cushions at the foot, to have it separate (like two partial twin beds) from below your hips to your toes. We like it this way as it is easier to get out of bed. So there is room to put my cpap on a tray with short legs, on the floor by my bed.
Often we are staying in a park with no electricity so then I hook it up to a battery booster pack. Fortunately for me when I was being monitored during first cpap use my counsellor was a camping person so he hinted that I should buy a battery booster pack (for starting your car if you run down your batteries) instead of the expensive one that the cpap company sells. I have a Canadian Tire housebrand and it has worked just fine. Eventually it needs to be recharged.
In the morning I put the CPAP back in its carry case on the floor between couch and side sitting box. The battery goes inside the box seat on my side.
It is a nuisance like rolling up your sleeping bag but it sure is nice to have a brain once again functioning on all cylinders so it is worth it.
After awhile my husband decided he didn't really have enough leg room. However instead of putting the board and all the cushions back he built a narrow two legged table that has one side resting on the side box seat that holds the large cushion. The narrow cushion fits on top of the 'table'. There is still enough room to get out of bed without stepping on my cpap. During the day the 'table' fits inside the box seat on his side.
Hope this helps, if it doesn't make sense, let me know and I will try again.
PS I was warned that if you are taking your machine across the border you might want to have some evidence that you bought it at home.
