Both! The prices you see can be for just one pillow or for a set of two – or even four! It is extremely important that you very carefully check out the listing for pillows you are looking at. Some state that the price is for a pair, but you can never be sure until you find the price for your product on the relevant Amazon page. Very often you will find the price is central on the Amazon listing, but if it is not listed then make sure you find out the answer.
