Frequently Asked Questions

Is it soft, medium, or firm?

It is the plush-but-supportive middle — the fill holds its loft so your neck stays aligned, without the brick feeling of firm foam. Side and back sleepers both settle in well.

How thick is it and who is it for?

Compare the loft in the photos to what you sleep on now — side sleepers want the fuller loft, back and stomach sleepers the lower one. It holds its height instead of pancaking by morning.

Does it go flat after a while?

The fill is high-rebound, so it springs back instead of flattening — that is what separates it from the budget pillows that turn into pancakes in two months.

Can I wash the whole pillow?

The cover is removable and machine washable on most of these — the core itself stays fresh with airing. The zip cover is the part that gets washed in the normal rotation.

What is the wedge shape for?

It props you up for reading, TV, and reflux-friendly sleeping at the angle shown in the photos. It also fills the gap between mattress and headboard if yours has one of those.
