When designing our blankets we noticed many buyers of other blankets complaining about the weight being either too light or too heavy. The idea of recommending a blanket weight based on body weight didn’t seem right to us. A larger blanket would spread the weight out a lot while a smaller blanket would concentrate it.
We began our process by researching why other sellers use body weight recommendations. We read every research and medical paper on the subject and simply could not find anything that supported their weight recommendations. We determined that an early seller simply made it up and other sellers just copied them.
In order to solve the weight issue, we did our own user testing using competitive blankets as well as our prototypes. We measured the total blanket weight and the square feet in order to calculate a weight per square foot of each blanket. Not surprisingly, they ranged from what we would consider very light to extremely heavy, which explains why so many customers of competitive blankets had weight complaints.
We had several users ranging from age 4 to 72 test the different blankets and score them from one to five, with one being way too light, 5 being really heavy, and three being just right. Using this method, we were able to determine a weight per square foot for our blankets that nearly everyone agreed to. So, if you cut a 1’x1’ square out of any of our blankets, they would all weigh about the same. We solved the weight problem once and for all, so all you need to do is pick a size and the weight is already optimized.
