Cotton [Better Weight DistriBution] we apply 4×4 square pockets to hold filling material, and the intensive stitchings help to fix the filling material in place better so that the weight of the blanket is distributed evenly [Multiple Weight Selections] The blanket weighs 7 lbs, size 41x 60, it is a smaller blanket made with 6 to 9 year old children in mind, it is also perfect for adults using a throw on sofa or recliner [Safe Filling Material] The filling material inside the PULI HOME weighted blanket is Micro-glass Beads and Poly Fiber. We feed less glass beads in pockets around the edges of the blanket, and concentrated more of the weight in the central areas to cover your body more effectively, the pressure of this 41×60 7lbs blanket is 0.4lbs/sq.?ft, an ideal weight for kids [More Secured Ties] We installed 8 straps on 4 sides of the blanket to tie with blanket cover, which will secure the blanket staying in the cover neatly. [Spring Autumn Use] The thickness of the blanket is most suitable for spring and autumn use. A warm blanket cover is recommended to use together with the blanket in winter.
