cat hammocks

HELP!! I have spent the last 45 minutes trying to search the internet for PCV cat hammocks that you can make yourself. I saw a few about 3 or 4 weeks ago, but can't find them again. I have the PVC, just would like a picture to follow for construction. Any help would be appreciated.

I bought one last year-the frame was wood and metal but none of my cats liked it. It swings a bit when the cats jump on it and the didn't like that so I donated to my cat rescue group. Perhaps if you have one when they are kittens and get used to it??

Did you try looking under cat furniture.

Well, these aren't instructions, but maybe by the picture you can figure some of it out?

Thanks for the picture link. That is quite close to what I am looking for. I would put the fabric around the top PVC pipe, so it wouldn't have the swinging part. I'm sure my cats wouldn't like the swinging motion either - a lot of what I saw was attached by springs, or loops. I want the fabric tight, so the bottom is flexible , but nothing moves too much. And if I make one, and my cats don't like it, it hasn't cost me a lot of money.
I looked under furniture, beds, everything. I was amazed at the sites that were listed that had nothing to do with CATS!!!
So, I thank you both for the response.

Here's a couple of sites

My cats like our camping chairs. Like these. So once in a while I put them out, and it's like a "new" bed. The are pretty similar to the hammock cat beds I saw, but higher so the cats like that too. Ours didn't cost that much and we've had them for close to 10 yrs.

I have one of those camping chairs - it's made out of mesh. That's what gave me the idea for a hammock - how much our cat loves to sit in it and claw at the mesh. Thanks.
