First, the place.
A heated mattress pad goes on the mattress or futon with the sheet over it, so it does not touch the skin directly. An electric blanket is a blanket you put over or under you; a heated floor mat is spread on the floor where you sit or rest your feet.
In Singapore, JPHEAT sells heated mattress pads only. The four heated floor mats (50×60 cm to 200×120 cm) are Japanese AC 100 V models and are not sold in Singapore; their specifications are on the site for reference.
Check the size in cm.
Measure the bed and the area you want warm in cm. The two pads sold in Singapore:
- Heated mattress pad Single JPT100J: about 190×100 cm. Covers a single bed, for the whole body.
- Heated mattress pad Half JPT7080J: about 70×80 cm. For one area, such as the upper body, the middle or the foot end.
Power in Singapore.
The pad itself runs on low-voltage DC 24 V. The supplied adapter takes AC 100–240 V, so it works on Singapore’s 230 V household supply, and Singapore orders include a UK 3-pin (Type G) plug converter, the socket type used in Singapore. The pad is not battery-powered: the adapter stays plugged in while you use it.
Temperature and timer.
The temperature is set between 20 and 50 °C, 1 °C per press. The off timer runs 1–12 hours in 1-hour steps; setting it to 00 cancels the timer, and the pad then stays on until you switch it off.
Use the off timer when you use the pad at bedtime, and switch it off when it is not in use. In an air-conditioned bedroom you can choose a lower setting to match the room.
Start low, use safely.
Start at a lower temperature and find the one that suits you. For long use of a heated mattress pad, about 30–38 °C is a guide. Keeping one part of the body on a high setting for a long time can cause low-temperature burns. When small children, older people or anyone less sensitive to heat use it, stay close by.
Care and storage.
The pad cannot be washed in water or soaked. Switch it off, unplug it and wipe it with a well-wrung cloth. Fold it for storage only after it has cooled; see the included manual for details.

Can I buy the heated floor mats in Singapore?
No. JPHEAT’s four heated floor mats are Japanese AC 100 V models and are not sold in Singapore.

What happens if I set the timer to 00?
Setting 00 cancels the timer, and the pad then stays on until you switch it off. The timer can be set from 1 to 12 hours; please use it when you sleep.
