Frequently asked questions

Who should choose the Adjustable Memory Foam Pillow?

Choose this pillow if you are unsure which pillow height works best for you, if you change sleep positions often, or if you want more control over firmness. If you prefer a fixed contour shape with targeted support zones, the Ergonomic Memory Foam Pillow may be a better fit.

What makes the Adjustable Memory Foam Pillow different?

The Adjustable Memory Foam Pillow is designed with removable support layers, so you can fine-tune the pillow height and firmness based on your sleep position and comfort preference. Unlike a fixed pillow, it gives you more flexibility to find a setup that feels right for you.

How do I adjust the height and firmness?

Open the pillow cover and adjust the removable insert layers inside. Use fewer layers for a lower, softer feel, or add layers for more height and firmer support. We recommend starting with the medium setup, then adjusting after a few nights.

Which sleeping positions is it best for?

It is suitable for side sleepers, back sleepers, stomach sleepers, and combination sleepers. Side sleepers may prefer a higher or firmer setup, while stomach sleepers often prefer a lower profile. Back sleepers usually start well with a medium height.

Will it feel too firm at first?

Some users may need a short adjustment period, especially if they are switching from a soft or flat pillow. Try the pillow for several nights and adjust the layers if needed. The slow-rebound memory foam is designed to feel supportive while still cushioning your head and neck.

Can this pillow help with neck or shoulder discomfort?

This pillow is designed to help support your head, neck, and shoulders in a more comfortable resting position. It may help reduce discomfort caused by an unsupportive pillow, but it is not a medical device and is not intended to diagnose, treat, or cure any condition.

Is the pillowcase washable?

Yes. The pillowcase is removable and washable for easier daily care. Remove the cover before washing and follow the care instructions on the product label. Do not machine wash the memory foam core or insert layers.

How long does it take to expand after unpacking?

After unpacking, gently fluff the pillow and allow it to fully expand before use. Most pillows regain their shape within a short time, but cooler environments may require longer. A light new-foam scent can be normal and usually fades after airing out.
