@Vicki625 If you purchase quality sheets and pillows, they should last a good while.
I purchased pillows from a big box store in bulk, and the pillows are rotated between which ones are on the bed and two extra in the closet. I buy down alternative filled pillows -- they can be washed and fluffed in the dryer as needed.
I purchase quality sheets sets in all cotton, at least 600 thread count. They stay crisper if you do not drown them in fabric softener and go easy on the bleach. Cotton does not snag as readily as microfiber and does not get that dryer grey appearance either.
My pillows last about 2-3 years. I do use pillow protectors on them.
My sheet sets last about 2 years as well. I rotate 2 sets and keep an "old" set which in the closet for emergency use.
My occupancy is about 250 nights a year.
