I purchased these featherbeds to make my two air mattresses more inviting and comfortable for my guests. The process: I put a thin tempurpedic on top of the air mattress (to protect the air mattress from stray feathers), then layered this 5" featherbed with a mattress pad on top, encased the featherbed and tempurpedic with a fitted long staple Egyptian cotton sheet, then layered a matching top sheet. Next I covered a 550 fill power duvet with a high quality duvet cover, added 3 down pillows with matching pillow cases, and layered a cotton matelasse blanket at the end of the bed, topped with a linen throw. By all accounts, the results were heavenly and I credit these great featherbeds for my guests' peaceful sleep.
