Have you looked at Taylor King? They have a whole line called Taylor Made. They make a very nice quality product.

For my 16 pound cat, I use an extra large bath towel; I think they are sometimes called bath sheets. Found one in a color very close to the sofa. It drapes over the back of the sofa and the back cushions and as the cat lies there, it forms a sort of hammock effect that the cat really likes. I adjust it back to normal every morning. It's large enough that it doesn't fall between the sofa back and the back cushions, and I think the terry cloth helps it not slide as much, as well. If you have really floppy cushions on the back of the sofa, you could also look into replacing the stuffing with a firmer type of foam (or whatever they are stuffed with).

We just bought one of those expensive foam mattresses. It does have the memory foam on the top and fused to the bottom layer of foam. We have a full size and it was on sale for $549. Free shipping. Thing came all rolled up and stuffed in a box and it was amazing to see it undo itself and settle down. We love it. We also saw them in box at Walmart. Not sure of the quality. There was a sample piece to look at. Was in the $200. price range. WE have had ours for a couple of weeks or so and every night it is a pleasure to get in bed. We are sleeping so much better. Some of the aches and pains are getting better. There is good support and yet it gives to accommodate hips and shoulders. The cover is just a heavy weight fabric with a LONG zipper on one side. I did buy a nice thick cotton mattress pad and that would really be all you needed for a cover. I bought the deep model, our mattress is 8 inch thick. The deeper model mattress pad, About $20.00 pulls under nicely with the elastic so it stays put. I was afraid it would slip around and it does not. So we are very pleased with what we are sleeping on. Chris

Unfortunately your cat will come back no matter what you do. I️ have never found anything to take that cat smell out and even if you don't smell it the cat will. I️ have gone through numerous area rugs after our older cat peed on them. And he even went on the new ones. So now I'm waiting for him to go to cat heaven before I️ spend any more money on new rugs.
