Do Mattress Protectors Make You Sweat?

Many science-based studies stress the importance of sleep in a healthy lifestyle. Establishing the correct temperature for the body to rest well is an important factor to consider. Shivering with cold is not conducive to a good night’s rest but is easily remedied with extra bedding or room heaters. 

Tossing and turning from feeling too hot and sweaty can be just as uncomfortable and not always alleviated by air conditioning or fewer blankets. Do mattress protectors make you sweat? Here’s everything you need to know.

How Can A Mattress Protector Make You Sweat? 

A quality mattress is an expensive item today but an important aid to sleeping well and a good investment for health and wellbeing. A mattress protector is also a practical choice to preserve the underlying mattress from soiling, sweat, and spills as well as dirt, mites, and allergens. 

For this purpose, the protector is coated with a waterproof membrane usually made from vinyl as being the most effective material. This plastic barrier has the disadvantage of not being breathable i.e. does not allow air to circulate through to the mattress. This can cause the sleeper’s body to overheat resulting in a sticky and sweaty sensation and an uncomfortable night.

What Types Of Mattress Protectors Are There? 

Three main types are available: ‘fully fitted’ covers just as a fitted sheet does whereas ‘encased’ completely covers the mattress including the underside. The third option is an ‘elastic strap topper’ which lays flat on the mattress and is fitted with ties around the four corners.

What Materials Are They Made Of

The waterproof, generally less expensive protectors, are made of materials containing plastics. Other options include cotton and polyester and specialist materials such as bamboo and Tencel.

What Is The Best Choice To Avoid Night Sweats? 

Although vinyl is waterproof there are concerns about overheating and possible leakage of toxic gases. Polyurethane is also waterproof and more breathable than vinyl. Cotton is a soft and breathable alternative but many customers today are turning to the cooling mattress protector

Natural latex is often used in these toppers and Tencel, produced from botanical fibers, can be blended with cotton or polyester for a cooling effect.

What About Bamboo Mattress Protectors? 

This is the material of choice for an increasing number of buyers who want to preserve their mattresses and have a good night’s sleep. These are high-end on price but with so many advantages may well be worth considering. 

Bamboo is a highly sustainable eco-friendly natural product that is durable, hypo-allergenic, and anti-bacterial. It is also acclaimed for its moisture-wicking properties, softness, and sheen. This too can be blended with cotton or polyester for an ideal protector for the mattress.

Are There Other Options? 

Manufacturers are constantly seeking to produce the best blends that are effective and low on cost but vinyl is still popular. To reduce the overheating effect, a cotton mattress pad can be placed between the cover and the sheets. 


A good mattress should last for many years. Protecting the mattress is well worth the expense but a careful choice of types and materials can avoid the downside of sticky sweaty nights. Bamboo sheets appear to be an excellent choice.
