How to Wash a Memory Foam Pillow: The Yourzzz Care Guide

Key takeaways

• The outer cover (Tencel and polyester blend) is removable and machine washable at 40°C (104°F).
• The inner cover and the filling cannot be washed. Washing the outer cover does not change how much filling is in the pillow.
• For hygiene, replace the pillow after 5 years at most. Some users replace it every 3 years.

Which parts of the Yourzzz pillow can you wash?

The Yourzzz pillow has three layers, and only one of them goes in the washing machine. This table shows the difference.

If you own a different pillow, follow the care label on that pillow. This guide covers the Yourzzz pillow only.

How do you wash the outer cover?

1. Remove the outer cover. Take off your pillowcase first, then take the outer cover off the pillow. The inner cover and the filling stay together as one pillow.
2. Wash it at 40°C (104°F). Use your machine's regular setting at this temperature. Do not go above it. Check the care label on the cover for anything else.
3. Let it dry completely. Put the cover back on the pillow only when it is fully dry.
4. Put the cover back on. Fit it neatly over the inner cover, then add your pillowcase.

While the cover is in the wash, leave the rest of the pillow as it is. You do not need to touch the filling.

Can you wash the inner cover and the filling?

No. The inner cover and the filling are not washable. We do not have a safe washing method for them, so we advise against trying one. The filling is a mix of memory foam flakes and polyester fibers inside a cover with a memory foam sheet. Getting that wet is a risk to the pillow's shape and feel.

This is the honest limit of the design. The outer cover takes most of the day-to-day wear, and it is the part you can refresh. If the inner part of your pillow is soiled and you are unsure what to do, contact us at info@yourzzzpillow.com or (844) 291 7392 (Monday to Friday, 9 AM to 4.30 PM CET). Our frequently asked questions cover other practical topics as well.

How often should you wash the pillow cover?

We do not give a fixed schedule, because we do not have research to back one up. A practical rule is to wash the outer cover when it looks or smells like it needs it. Wash your pillowcase along with your regular bedding.

Does washing change how the pillow feels?

Washing the outer cover does not remove or add filling, so the height of the pillow stays the same. Height comes from the amount of filling inside. If your pillow feels different after a wash, check that the cover is fully dry and sits flat on the inner cover.

Fit matters because a pillow that is too high or too low leaves a gap or a bend between your shoulder, neck and mattress. A side sleeper usually needs more support under the neck than a back sleeper. A stomach sleeper usually needs a lower pillow. Mattress firmness plays a role too, because a soft mattress lets your shoulder sink in. Our Yourzzz sleep guide goes deeper into sleeping position and pillow height.

A note on scope: a well-fitting pillow supports your head and neck, but it is not a treatment. If you have neck or back pain that does not go away, or you have numbness or tingling in your arms, see a healthcare provider.

How is the Yourzzz pillow adjusted?

Yourzzz is a pillow you adjust yourself at home. You order it first, and you adjust it once it has arrived. The algorithm behind the advice was developed by Dutch physiotherapist Thijs van der Hilst. It works like shoe sizing: a store that sells one size rarely has yours.

1. Order the pillow. One pillow, $89. Buy 2 and get 10% off.
2. Use the calculator. Once the pillow has arrived, answer four questions on our calculator page: your height (inches), your weight (lbs), your sleeping position (side, back or stomach) and your mattress firmness (soft, medium or firm).
3. Take out the recommended filling. Use a kitchen scale. The calculator also shows the final weight of the pillow. Without a scale, a 200 ml (6.8 fl oz) glass holds about 50 g (1.8 oz) of filling.
4. Keep the rest. Store the extra filling in the storage bag, so you can adjust again later. The bag also works for traveling with the pillow.

Removing filling makes the pillow lower and softer. If you later want it higher, extra filling can be ordered separately. Learn more about the pillow itself on our Yourzzz pillow page.

When should you replace the pillow?

Because the filling and inner cover cannot be washed, replacement is the hygiene reset. Replace the pillow after 5 years at most. Some users replace it every 3 years. The pillow comes with a 5-year warranty on material and production faults. Normal wear and changes in firmness are not covered.

Want a pillow you can adjust and keep clean?

The Yourzzz pillow costs $89 and ships free. It comes with a 100-night trial. If you are not satisfied, you can return it. Return shipping is at your expense, and you include the return form. The refund goes to your original payment method 5-7 business days after we receive the pillow.
