AK TRADING CO. 2.5" Thick CertiPUR-US Certified Convoluted Hospital Mattress Pad, Egg Crate Foam Foam Sheet | Mattress Pad (Medical Bed, Mattress Topper, Chairs) - Made in USA (2.5" x 18" x 72")

Convoluted polyfoam, also known as egg-crate foam, is a popular choice for topper material. The term refers to polyurethane foam shaped with ridges to create a contoured (or convoluted) surface that alleviates aches and pains in the sleeper's most sensitive areas. These toppers also isolate motion fairly well and produce no noise when bearing weight. Convoluted polyfoam toppers tend to be much cheaper than those made from other materials, making them a high-value option. In addition to bedrooms, they are commonly used in guest rooms, dorm rooms, and hospitals.

Convoluted Foam Mattress Pads are made of high-quality medical-grade urethane.

Convoluted Foam has an egg crate texture that softly contours to your body's lesser points of contact to reduce pressure points, prevent soreness, and relieve stress, joint pain, muscle pain, arthritis symptoms, and even help improve circulation.

Egg crate toppers are popular with healthcare facilities because they allow air to flow under the patient, which is important for preventing bed sores and fevers. Warnings: Foam packages need to be opened immediately upon arrival. Do not let foam sit unopened for more than 1 week. Don't open with a box cutter (you'll cut the foam). Use a ball point pen or keys. When unpacking foam, allow the foam to sit for 3 to 5 days so foam can breathe and return to its original size and form.
