Bummer.
but it gets better.
Our Flair sleep sofa air mattress developed a pretty good leak on our last trip out. Didn't have much luck (at first) trying to find the leak and so researched the idea of replacing the mattress with a new one. After some effort I was able to locate Flair Interiors, who manufacture most of the furnishings that go inside our RVs, Forest River and Keystone products in particular.
I sent them an email to their customer service address and received this prompt and helpful reply:
Good morning. Thank you for your inquiry.
Flair no longer carries the tan air bladder with straps as the company that made them does not any longer. Flair does not sell products to the retail public any longer as Flair only sells to the RV manufacturing facilities. You may order through the RV Manufacture such as Forest River, Thor etc….
OR
Flair now carries an INTEX Brand Air Bladder ~ Dark Blue Vinyl / flocked top
60” Queen Intex Part Number is 66777E
54” Full Intex Part Number is 66776E
These mattresses are available for purchase online at places like Amazon.com OR at stores such as Sears/Kmart and Gander Mountain. The cost is usually between $50.00 and $70.00.
Thank you,

So I learned a few things.
1. The correct name for the mattress is "air bladder" which sounds like a medical condition.
2. That fuzzy stuff on top is called "flocking"
3. The original mattress, oops, the original air bladder is no longer made, and Flair now uses a different one that seems to be pretty much "off the shelf"
4. Flair prefers to sell only to RV manufactures but will point you in the right direction
5. Flair's website is here, and some of it doesn't work.
http://flairsandbox.com/
6. I shopped Amazon and others for the Queen size (the part number is valid) and found them under $40.
And then I got lucky and found where the seam had let go in my original "air bladder".
I prefer the original as it has a method, by Velcro straps, to secure the air bladder to the sofa. So if my fix holds, I'm good. If not, a replacement mattress (oops, air bladder) will be here well before our next trip.
