Bamboo fitted sheets and what makes a good one

Short answer: A good fitted sheet has corners deep enough for the mattress and elastic all the way round. Those two things decide whether it stays put all night.

Corner depth first

Measure the depth of the mattress and find a sheet with corners at least as deep. If they are too shallow, the elastic sits on the edge and slips. See bamboo fitted sheets.

Elastic all the way round

Elastic only in the corners holds less well than elastic running all the way round. That is the detail separating a good sheet from a cheap one.

The fabric against the mattress

A fitted sheet lies directly under you all night. If the material is dense, it turns clammy if you sweat. See bamboo bedding.

Wash without stretching

Do not pull at the sheet while it is wet. Wet fabric stretches permanently. See washing and care.

For a thick mattress

If you have a topper on it, the depth has to be measured with it on. See home and homewear in bamboo.

Frequently asked questions

How do I measure for a fitted sheet?

Measure the length, width and depth of the mattress, including any topper.

Why does my fitted sheet slip?

Because the corners are too shallow for the mattress, or because the elastic is only in the corners.

Is elastic all the way round important?

Yes. It is the detail that best prevents the sheet from slipping.
