This is probably the number one question I get when a client is working with me on designing a new Weighted Comfort Quilt.
There is a lot of really helpful information out there about weighted blankets, but there is also a lot of misinformation. Since I sell therapeutic weighted products, I have read and researched a lot, and for me, the best reference that I have found is "The Weighted Blanket Guide", written by Eileen Parker and Cara Koscinski. Ms. Parker has Autism and Sensory Processing Disorder and ran her own Weighted Blanket manufacturing company for several years; Ms. Koscinski is a Pediatric Occupational Therapist, has authored several books on OT and Autism, and her two children have Autism.
On the subject of how much a blanket should weigh, they write:
“Blanket weight is an important choice, and there are no absolutes and no magic formulas to determine the weight. The guideline of 10 percent of body weight plus one pound has spread online. While the formula is not accurate for all people, it is a good starting point for children. For example, a seven-pound blanket for a sixty-pound child would be a good weight.
There are contradictions to the body weight rule. For example, Champagne et al. (2007) writes: “Body weight is generally not a factor influencing the amount of weight preferred.....Especially for adults, body weight isn’t a reliable indicator of the person’s desired weight on them.”

In my experience, my adult clients have preferred weights that have often been higher than 10% of their body weight, and in a few cases, much lower. Having said that, I think the 10% rule is a good safety guideline to use with children. It is also a good starting point for helping adult users find their preferred weight. For example, if a person weighs 150 pounds, they could try a 15 pound blanket to start. From there they could determine if it is too heavy or too light, and adjust accordingly.
This is why KP Quilting Studio has six demo Weighted Comfort Quilts (ranging in weights from 6 to 28 pounds) and a "Try-Before-You-Buy" program. I really believe that people need the opportunity to try out a weighted quilt for a sustained period of time, in their own home, in order to find the weight that is right for them. I would much rather make a Weighted Comfort Quilt for a client knowing that it is the right weight for them as opposed to "sewing and hoping"!
