What are the advantages of a larger size blanket?
Some people may feel uncomfortable due to the size gap between the blanket and the bed with a smaller size blanket such as 70 x 130 cm or 80 x 150 cm. It is suggested to use the larger blanket and it also prevents sliding or shifting while you sleep.


 
Why is there no additional heating area in the larger-size blanket?
Due to safety concerns and the duration of the product life consideration, the heating element inside the blanket should not be folded or exposed. Such element may malfunction or overheat to stop generating warmth. Thus, it is designed that the heating element stays the same size with heating up the same size area without risking being damaged.


 
Why does the temperature of the blanket in the sleep sense mode (temperature setting 1) decrease slightly after a period of time?
Generally, our core body temperature fluctuates throughout the day.  As it is the highest in the afternoon, and decreases at night to prepare our body for sleep. After we fall asleep, only a minimum level of heat is needed.  

Wellcare's 2-in-1 BBC Design blankets allow the blanket temperature to adjust accordingly to our core body temperature fluctuation at night and are designed to provide sufficient temperature because any unnecessary heat may lead to stuffiness, perspiration, or dry mouth to interrupt sleep and cause poor sleep quality.  Although the blanket's temperature decreases a little in setting 1 (sleep sense mode), it still provides adequate warmth for you to stay warm.



 
This blanket seems thicker and heavier than the ordinary ones, are there any additional benefits?
With the meticulous selection of multiple layers of fabrics, when the product is used as an overblanket, it produces a weighted effect to fit to body contours closely and offers better coverage so you wouldn't lose too much heat when you toss and turn at night.

1. To warm up the bed before you go to sleep
2. To keep your feet warm to promote healthy blood circulation for a restful sleep
3. Keeping your bed at a constant temperature to prevent you from waking up in the middle of the night due to 
    being too hot or cold
4. To be energy efficient and environmentally friendly
5. To help to create a comfortable bed climate for us to fall asleep easier

Depending on the surrounding conditions (room temperature, mattress, sheet fabric or thickness), sometimes it may take up to 15 minutes for the underblanket to get warm after it has been switched on.  You can set the temperature at the highest level in the begining and adjust the temperature when the underblanket is warm.

I notice that it is mentioned in several areas of the manual and the safety reminder reminding me not to fold the blanket. What is the best way to store my underblanket when it is not used for a period of time?
When an underblanket is folded improperly, the heating elements embedded inside may be deformed or damaged. It may be dangerous to use the blanket and may shorten the product's service life.

  • Keep it flat or roll it up, store in a dry and cool place without placing any thing on it;
  • Fold it properly and put it in the original packaging box. Store it in a dry and cool place without placing any thing on it

Wellcare uses better and thicker fabrics to serve as a buffer space so heating wires are not sharply bended when the blanket is folded.

Is the heating area also bigger in the larger size electric underblanket?
Although the blanket size is larger, but, the heating element can not be placed under one's head or covered by a pillow to prevent overheating. Therefore, the heating area remains the same as other Wellcare single-sized underblanket, 80 x 150 cm.

Usually the size for single underblanket is 80 x 150cm, why would I need a larger size?
Many people wonder why the conventional single electric underblanket (80 x 150cm) is small than the single-size mattress. Some people who have the uneasy feeling that the blanket does not cover the bed similar to wearing a size too small of garment, may feel uncomfortable. Since Wellcare takes customers' voices seriously, we offer an underblanket with the size (90 x 200cm) that fits your mattress. We hope that everyone can enjoy a good night sleep.

What are the benefits of an underblanket with 3 densities of 4D DWF circular hole?
4D DWF holes with different densities have formed different sizes of matrices that help users to place the underblanket on their mattress in the right position : 

Head area - lowest density (no heating)
Body area - mid density
Feet area - highest density



Which side of my electric underblanket is the upper side?
For most of Wellcare's electric underblankets, there are 2 fabrics used for upper and bottom sides.  Depending on your preference, you can choose which side to use close to your body.  However, we highly suggest to put the eco-fleece side downward if your mattress has a slipery surface.

Please pay attention to the underblanket with additional foot warmer function, the part with higher density circular holes should always be placed by your foot.

Before you use the underblanket every time, check if the blanket is completely flat without being folded or creased.

As invisible as air, the 4D DWF's dynamic warmth flow indeed surrounds our bodies.

Depending on the environment, everyone's awareness of the warmth flow may differ.  According to the test results, products equipped with 4D DWF outperform other similar products on the market in terms of breathability, heat transmission area, the speed to reach a certain temperature, and the ability to maintain desired temperature.
