Beds are dressed with more pillows than anybody sleeps on, and the useful number is smaller and more considered than the decorative one.
The Sleeping Pillows
One per person, at the correct height for their position.
That is the whole functional requirement for most people. A second pillow stacked underneath is almost always compensating for the first being too low, and it works poorly because two pillows shift relative to each other.
Fixing the height of one is better than adding a second.
The Ones That Earn a Place
- A pillow between the knees for side sleepers
- A pillow under the knees for back sleepers
- A body pillow for anyone changing sleeping position
- A spare in the cupboard for guests and for illness
- A wedge for anyone using one on medical advice
Where a single pillow can be set to different heights, of the kind at nuzzle-pillows.com, one item covers what would otherwise need several, which suits a household where people sleep differently.
Decorative Pillows
They are a styling decision rather than a sleep one, and there is no problem with that.
What matters is that they come off at night rather than being slept on, since cushions are not made to support a head.
Somewhere for them to go is worth planning, or they end up on the floor.
Two People, Two Different Pillows
The point that matching sets obscure. Two people in a bed frequently sleep in different positions and have different shoulder widths.
They need different pillows, and buying a matched pair means one of them is wrong.
Matching pillowcases over different pillows solves the appearance question entirely.
The Spare
Worth having for practical reasons: guests, illness, a pillow in the wash, and propping somebody up when they are unwell.
Stored somewhere dry, in a protector, and replaced on the same schedule as the ones in use.
Replace on a Rotation
When a new pillow arrives, the oldest leaves the house rather than moving to the spare room.
That is what stops a guest bed accumulating the household’s worst pillows.
Protectors on All of Them
Including the spare, which will otherwise sit in a cupboard collecting dust.
Count What You Sleep On
Most beds have three times as many pillows as people use.
Buy Fewer, Better
One correct pillow beats three approximate ones.
