When buying a pillow, you should consider your body type, preferred sleeping position and the hardness of your mattress. Altogether those factors define how your spine is aligned during sleep. The most important factor is the sleeping position - it defines the right height of the pillow to support your spine and improve blood circulation. Side sleepers on average need taller pillows compared to back sleepers, while stomach sleepers require minimal neck support.

The second thing to consider is body shape, because someone tall or with wide shoulders would need a higher pillow, while someone with a smaller frame, would be better suited to a lower pillow.

The last point to consider is the mattress - if you have a soft and elastic mattress which you'd sink deeper into, we'd recommend a flatter pillow. However, if your mattress is a bit harder and you sink just a little, your pillow should be slightly higher.

For side sleepers, who lay slightly elevated, a good option can be the Emma Adapt pillow. For stomach sleepers, who are more likely to sleep flat, the Emma Comfort Cooling pillow, with the middle layer removed, may be more comfortable. For back sleepers, the most ideal position for a night of good sleep is normally the supine position and for that the Emma Adapt Cooling pillow would be the right choice.

All Emma pillows are designed to fit any body type and to be adjustable; whether by adding/removing layers or simply flipping the pillow over.

The pillows that have more than one layer and allow adjustments are the most ideal, because they have multiple layers that can be added or removed, depending on the person's needs. At Emma, we have the Emma Adapt, Emma Adapt Cooling, Emma Hybrid and the Emma Comfort Cooling.

For example, one layer is ideal for stomach sleepers that have a soft mattress and very narrow shoulders. Two layers is recommended for side sleepers with small shoulders or side sleepers with wide shoulders but a soft mattress. Three layers is ideal for side sleepers with wide shoulders and a hard mattress or back sleepers with reflux problems.

It's not recommended for babies and small children to use a pillow. In general, most pillows sit too high for their small necks to be properly supported.

Our Emma Adapt, Emma Adapt Cooling, Emma Comfort Cooling and Hybrid pillows are all equipped with different inserts. This gives you seven different ways to make the cushion your own by flipping it or removing layers to adjust the firmness and height of the pillow.

The Emma Comfort Cooling pillow is the softest. The Emma Adapt pillow is the hardest, but only without adjustments.

It's not an obligatory item, but it's recommended to have a pillowcase to keep the pillow cover clean and also to match your sheets. Our pillow covers are washable and have a nice touch.
