While the shape remains consistent, there are a few wedge pillows to choose from based on the material and design.
1. Memory Foam
A memory foam wedge pillow adjusts to the contours of your body. Memory foam responds to heat and pressure and retains its shape after every use. So, you will have a cushion that feels customized to the needs of your body.
Polyfoam wedge pillows are more firm. They bounce back to shape as soon as the pressure is released. So, these wedge pillows might not conform well to the contours of your body like a memory foam wedge pillow.
However, people with certain conditions might find it helpful for firmness and support. For example, women can use it as a pregnancy wedge pillow. Its firmness ensures that you stay in a position without moving in your sleep.
The surface of a wedge pillow can be flat or contoured. If it is flat, you can use it as a leg wedge pillow or a back wedge pillow. If you are a back sleeper, placing this pillow under the legs will keep your spine in its natural alignment.
If you are a side sleeper, a contour wedge pillow is for you. The curves and contours on it will follow the curves of your neck and shoulders, keeping your spine in perfect alignment.
It can also act as an acid reflux wedge pillow for side sleepers. Sleeping on your left side will help in better digestion. In addition, a contour wedge pillow can help you sleep on your side while relieving the pressure on your shoulder and neck.
