I was so tired of digging through bedding in the linen closet to find the matching sizes of bedding that I thought I would give these ar try to make organizing easier. They are large enough to fit a CA King mattress pad, blanket, sheet set and comforter in one bag. We have beds ranging from twin to CA King and I was able to create a complete set of bedding for each of the beds in one bag. It's been great to be able to just grab a bag and change out a whole bed so easily. I used the extra bags to store extra blankets, pillows and throws. The only negative is that the material is thin and tears easily at the handles.  If I ever have to replace these, I'll be sure and get something a little sturdier.
