Check with the hotel desk to see if they offer their bedding for sale. We have stayed at a number of places where pillows and comforters are available for sale to guests. If they aren't, a little sleuthing can still lead you to where you can buy the hotel's bedding for yourself:
Check the tag on pillows and comforters for manufacturer information. Look for the large tag that threats "penalty of law" if removed by anyone besides the consumer. It should have the manufacturer name on it, as well as the style name or number of the particular piece. Armed with this information, you can then track down the manufacturer and order the bedding for yourself!
Have you ever purchased bedding for home based on a stay in a hotel? How did you go about doing it?
