Buy adjustable underpillow

Your pillow should fit you - not the other way round

For many side sleepers, one pillow is too low but stacking two or three doesn’t give reliable or stable support.

Fix poor pillow height for good

An adjustable underpillow lets you fine-tune your pillow height in 1 cm increments — to get consistent, comfortable support for any body shape.

Inside the Mylevel Underpillow:

Combine 2 cm and 3 cm layers to create heights from 2–10 cm in 1 cm increments. Choose responsive Reflex foam, pressure-relieving memory foam, or a blend of both to personalise comfort.

Because your needs can change over time, the setup can easily be reconfigured.

Set up guide:

Start with the most popular set up - one soft comfort layer on one blue springy layer and your choice of top pillow and test for comfort

Add or remove layers to get optimal support. Use your camera phone to check alignment

Check if you prefer the feel of the memory foam layers, if so, reconfigure layers

Insert your choice of layers into the stretch cover. It may take a couple of nights to fine tune your set up.

The Science

Because side sleepers have different body shapes and shoulder widths, pillow height should not be one-size-fits-all. Recent studies suggest that matching pillow height to shoulder width may improve comfort and ease neck muscle activity during side sleeping.
