The 4th pillow on the list is the Emma Pillow. This is a pillow made with three layers of foam that are removable so you can change the height depending on your sleep style.
But keep in mind, since the Emma Pillow only provides three customisations, you’ll never be able to get it perfect for you.
The Emma Pillow comes with a 100-night trial, a 10-year warranty, and free delivery and returns, but with a 5-7 working day delivery time. So, you’ll have to wait quite a bit before you get to enjoy the features the Emma Pillow has to offer.
