These deep pocket flannel sheets fit perfect on my queen deep mattress. I was sure to follow washing instructions. I washed them in cold water and added 1 cup vinegar to the rinse cycle, which is recommended to keep the sheets from pilling. I had never heard of doing this, so it's good to know. Now I keep a container of vinegar in my laundry room. The colors on this sheet set are beautiful and rich. The quality of the flannel is excellent...comfy and cozy, and just the right weight...not too thin, not too thick.
I ordered these sheets based on the reviews so am adding my voice here. We've had these sheets a couple of weeks, they're cozy and comfortable. The material is thick and perfect for winter! Pockets are the deepest I've ever seen and I love that about these so you can roll around without the edges pulling off! The only thing that would have made it a five star review was if there wasn't a seam along the length on one side, presumably to get the awesome pocket depth. It's not a big deal but I noticed it when I made the bed.
