1. Does the Ru9 mattress protector get hot?
As the sheet is directly in contact with the person lying on it, it is important to choose soft, skin-safe, and healthy materials. Many waterproof sheets are made of synthetic fibers that can cause itchiness and heat. However, you don't need to worry about that with the Ru9 mattress protector. You will have a comfortable night's sleep thanks to its 3-layer structure: The top layer is soft and smooth polycotton, the middle layer is a moderately thick cotton batting that enhances body support, and the bottom layer is 100% waterproof premium TPU certified safe.

Soft and absorbent Poly Cotton provides a cool and airy feel
The mattress protector is neither too thin nor too thick, offers softness, and does not make noise when you turn over. The polycotton layer wicks away sweat, keeping your back dry and preventing a stuffy, hot feeling when lying down for extended periods.
2. Advantages of the Ru9 mattress protector
With modern, environmentally friendly manufacturing technology, Ru9 offers customers a high-quality mattress protector with the following advantages:
Absolute mattress protection
The premium TPU bottom layer is 100% water-resistant, preventing liquids from seeping into the mattress. As it lies directly on the mattress surface, the Ru9 mattress protector also acts as a barrier, protecting the mattress from dust and dirt. This function is particularly evident in families with small children. When they are not yet aware of self-hygiene, children can always wet the bed while sleeping. Regularly cleaning the mattress would be very difficult, but thanks to the mattress protector, parents only need to wipe it dry and clean the protector.
Soft and safe for skin
With a 3-layer structure of cotton and batting, the Ru9 mattress protector maintains its softness for a refreshed feeling upon waking, without back or neck pain.
The surface consists of natural cotton fibers, certified safe for the skin, eliminating any uncomfortable itching when in close contact with the mattress.
