This is exactly the thing you don't think you need but now you can't imagine how you lived without it. It heats up quickly and definitely very warm on the highest setting which is what I use because I'm always cold. I'm 5'2" and it's a nice size for me - but note it's definitely throw size so keep that in mind. Warning... it will make leaving the couch more difficult if you have fur-babies! Mine loves it- he's next to me purring as I type this!
