How many sets of bedding you need
Short answer: Two sets per bed is enough for most people. Then you can change and wash without waiting for one to dry.
Two sets in rotation
One is on the bed, the other in the cupboard. With two sets you never have to plan the washing around the bed change.
Three sets if you sweat
If you sleep warm and change weekly, a third set makes everyday life easier. See bamboo bedding for night sweats.
Extra pillowcases
The pillowcase gets dirty fastest. A couple of extra pillowcases cost little and get used a lot.
For guests
The guest room should have its own two sets, so you do not borrow from your own bed.
Buy matching sets
If you buy matching sets, the pieces can be mixed when a single cover wears out. See bamboo bedding.
Lifespan
Bedding lasts many years if it is washed at 40 degrees without fabric softener. See how to wash bamboo bedding.
