Inner spring sleeper sofa

[Camping Flair]

I need to know the size of the sleeper sofa mattress in the 300ES. It isn't listed in the brochure or on line and my dealer is closed today. I looks like it might be a twin but not sure what sheets will fit.

Twin is probably a good guess. If you intend to sleep on it you may want to get a topper for it or an inflatable mattress to go on top of it. They are very uncomfortable.
