To choose the best isotonic pillow, ideally you should select one that is designed for your usual sleeping position. Ultimately, you'll have other choices to make, determined by your personal preference. You need to decide whether you want the traditional shape pillow or a contour shape. The density of the pillow is another consideration. Whether you prefer memory foam or synthetic will be something to ponder as well.
An isotonic pillow made from 100 percent memory foam is made to offer support to your head, your neck, and your spine, by keeping your body in alignment. When choosing your isotonic pillow, you'll want to be sure it is constructed with a ventilation system that allows airflow. This will keep the pillow, as well as your head and neck cool as you sleep. If not ventilated properly, memory foam material tends to retain heat and moisture, so be certain your choice of pillow will prevent that from occurring.
Many isotonic pillows will also incorporate some type of nodules constructed into the pillow. These are designed to provide comfort while adding support that you need. Read the packaging to be certain your isotonic pillow is pressure relieving. Otherwise, you could wake up with a sore and stiff neck and aching muscles.
Another consideration might be whether you'd prefer a pillow that includes a removable cover. This is a nice added feature, and it helps to keep your pillow clean and fresh. Be sure the cover is machine washable for easy care.
Check to be sure your isotonic pillow is mildew resistant. This could be an important issue, especially if you suffer from allergies or other similar health concerns. If you are allergy sensitive, choose a pillow that is hypoallergenic. These may be somewhat more costly, but it is a good investment.
Isotonic pillows are not only made with memory foam or Visco® elastic. Many of these are made with a synthetic fiber blend. Some isotonic pillows feature a combination of both memory foam and synthetic fiber. You may prefer polyester with a memory foam core, as it offers a traditional feel, with the extra memory foam layers for support.
Whether you choose a contour isotonic pillow or a traditional shape, be sure it is gusseted for extra support and durability. Some isotonic pillows also incorporate tiny beads for heat absorption, so you might want to consider that option as well. Thread count also is important, so choose one with at least a 300 thread count for better durability.
