I like the way goose down pillows feel, but I don’t like how they make me sneeze. I can’t have them in my house. I have a combination of bamboo pillow from Amazon and an assortment of soft and firm hypoallergenic synthetic ones from IKEA.
Like with all their products, pillows at IKEA come in different price ranges. I chose the more expensive ones, since they were still reasonably priced. The $2 ones they sell are similar to the Swedish pancakes in the cafeteria.
Like Paul, I put out one soft and one firm for each guest, so 4 total for the queen and 2 for each twin.
Dust mite proof pillow protectors are a must. There is nothing grosser than when you can see a stained pillow peaking out from the pillow case.
