You can wash the Tencel cover of the Nimbus pillow. Please do not wash the memory foam core, as the material can deteriorate with liquid contact. If you are concerned about the cleanliness and health of your pillow, we highly recommend purchasing an Ortho Mattress Supreme Pillow Protector.

There is no exact science for when you should replace your pillow. If you have a feather pillow, a simple stability test is to fold the pillow in half and see if it rebounds to its normal position. If you have a foam pillow, you should replace it every 18-36 months for continued support.

These are general recommendations and not rules; picking the right pillow is very subjective. Ideally, a pillow should align your head and neck with your spine, helping to improve sleep. If you are a side sleeper, look for a soft/flat pillow. If you sleep on your back, look for a medium thick and supportive pillow. If you spend most of your time on your side, look for a thick but soft pillow.
