California king mattress
20 years old, handles on side to flip.
You will need to carry it. We cannot help.
Good luck with someone wanting that...
I had such a worrying thing happen. For the first time since I adopted her, Ellie escaped my apartment. Usually I'm very careful when I open the door, but I had been on the phone and there was a knock at the door, so instead of hanging up and dealing with it, I told my mother to hold on a sec. It was an annoying Comcast person (they pretend to check how your service is, but really just want to try to upsell to you). If I hadn't been on the phone, I could have dealt with him easier, but with my attention divided between the two, I couldn't get rid of him. Standing there talking with the door open, Ellie just ran out. (The Comcast guy was actually the one who saw her escape.)
She took off, but luckily someone was walking their dog towards us, and the dog went crazy snarling and growling and snapping. She flattened herself against the walkway/sidewalk, and so I was able to grab her.
The Comcast guy apologized a lot, but I was still pissed off about it, and really really worried. Now that she's been out once, she seems to be eyeing the door a lot more.
Silly, silly Ellie, I don't keep you inside to be mean! The world is full of dangerous cat-eating dogs and cat-hitting cars and other cats who would kick your pampered butt! Stay inside, where it's safe.
