I no longer cringe in my bed, under my warm blanket, doing the horizontal potty dance because the thought of sitting on that cold seat is horrifying!
As a Cancer patient who is on chemotherapy, the first few days after chemo, cold is not my friend. I have to eat, drink and most of all, STAY warm. As the underside of my house is open to the elements, the cold travels its way up the plastic pipe, thru the porcelain, to the plastic seat, where my poor tooshie comes in contact and makes every muscle in my body tense painfully!
THESE ARE A GAME CHANGER! I now find myself saying "Aaahhh" when I sit on this wonderfully fuzzy and surprisingly warm seat at 3am. It makes a HUGE difference!
As far as installing the thing, it just wraps around the seat. It only hooks at the back (by the toilet seat bolts) with 2 small hooks. The rest of it just wraps loosely. This is probably not the best for a seat that a guy will use. Since girls don't lift the seat, the thing doesn't move!
I've been on/off mine 40 times in a week. Pulling that one to wash, put the other one on (I was not willing to even go ONCE without that cover) Will order a few more for extra backup.
I'll update after I wash it to see how that holds up.
UPDATE: Obviously I have changed them more than once since my first review. no issues with getting them on/off.
THE ONE ISSUE I DISCOVERED: BE CAREFUL when pulling out the plastic ring that holds the cover open. There is a little plastic piece that holds the 2 ends together to make a circle inside the cover. THIS COMES LOOSE AND GETS LOST IF YOU AREN'T CAREFUL! Didn't really register to me that the piece came off BOTH sides. I popped the ring out this morning to wash the cover, and when I went to replace it, I discovered that the little connector piece was missing! If I'm lucky it's in the washer with the next load, but we'll see. If not, I either have to order another one, or go to the home improvement store and buy a 1 1/2" piece of 1/4" tubing to connect them together.
Either way, these things are great! Still TOTALLY in love with them. Between the chemo and losing 40 pounds (so there is nothing to pad my tooshie) sitting on a cold seat in the middle of the night was one of my worst things I have to deal with. Now I don't think twice about getting up to go.

This toilet seat cover is a game-changer during chilly mornings! The material provides a warm and cozy touch, ensuring that dreaded cold seat shock is a thing of the past. It adds a layer of comfort to my bathroom routine, making those chilly moments much more bearable. Five stars for keeping my bum warm and happy

I ordered these after remembering a friend used to get them from Japan years ago. It's very nice to not sit on a cool or cold toilet seat!
These seem reasonably well-made, looks nice, and easily fits my toilet seat. Initially they are a little confusing to put on but after the first time or two you "˜get it'. I enjoyed the comfort and warmth, however, several weeks after I started using these I noticed the inside of the toilet lid would start to develop mildew in between my regular cleanings- ick! I think filling in the air space between the lid and the seat and also the seat and the toilet itself creates some airtight space that perhaps creates a too perfect environment for mold and mildew. I like these but don't want to grow mildew in my toilet so think I will only use them for short periods of time during the coldest part of winter or when we have a power outage and the house is cold.

I got this first product as a test, and I like it and I will be purchasing more!!!

I have a padded toilet seat with uncomfortable rips. Instead of buying a new one, i decided to give this a try. I love it!

It's the perfect cushy softness.

Easy to put on, and hasn't come off on its own.

The cheery blue perfectly matches my beach theme.

I only needed 1, but this was still a good deal with more.
