Is this blanket warm enough for winter?

Yes for most people as an extra layer. The brushed polyester fleece holds heat well, but it is thin, so very cold rooms may still need a comforter over it.

Does it work on a king bed?

At 90 by 108 inches it covers a king mattress with some overhang, though not enough to tuck under on all sides. It works better as a top layer than a fully tucked blanket.

Can I machine wash and dry it?

Yes. Wash cold on a gentle cycle and tumble dry low. Avoid high heat, which can melt the pile and worsen static.

Is it good for people who sleep hot?

Not really. The fleece traps heat and does not breathe like cotton, so hot sleepers usually do better with a woven cotton or lightweight quilt.

Does it attract pet hair?

Yes. The textured polyester pile grabs lint and pet hair, and a lint roller or rubber brush is needed to clear it.

Is it the same as a fleece throw?

It is the same flannel fleece material in a king size. Expect throw-like softness and weight spread over a much larger area, so it feels thinner than a small throw.
