Can children use the thermal sheet?

If you have small children at home and wonder if they can enjoy the benefits of the thermal sheet the answer is: yes, but with restrictions.

First of all, if your child still wears a diaper or pees on the bed, it is important that you choose a waterproof model.

This is because the direct contact of water on the wires can cause a short circuit and, in addition to damaging the product, it can also shock.

However, the good news is that most sheets with the Inmetro seal are made with waterproof material, eliminating this risk. When in doubt, it is always good to read the packaging carefully.

Purchase criteria: how to compare thermal sheet models

As you may have noticed, the thermal sheet is a product that requires special care, so we selected some points that can make all the difference at the time of your choice:

  • Bed size
  • Temperature
  • Shutdown
  • Voltage

Next, we’ll talk about each of these factors.

Bed size

Buying the thermal sheet of the correct size for your bed is essential, not least because it is attached by elastics and needs to reach the ends of the mattress.

There are specific models for single and double beds, and in the second case they can be of the common size, or for a king or queen bed.


As you may have noticed, temperature is the most important factor in a thermal sheet. Normally, they reach a maximum of between 36oC and 38oC, as a way to guarantee safety.

The best mattresses are those that have temperature control. Some have three or four levels of heat, and others have a gradual regulator.

Ideally, you should choose one of these models to not only have more control of the device, but also for the sake of comfort.


Thermal sheets from newer models tend to have an automatic shutdown system, and these are the ones you should choose.

This system guarantees total security in case you end up falling asleep and forgetting to turn off your device manually.

Sheets that switch off only manually are much more likely to overheat and, consequently, to short-circuit.


Before buying your thermal sheet, note its voltage. There is no rule, some are 120V, others 220V and there are also those that are bivolt.

If possible, choose the bivolt option, if not, make sure you are opting for the voltage compatible with the outlets in your home.
