No. Because our weighted blankets are designed to be smaller than traditional comforters, regular duvet covers will be too big. The only covers that we know are a perfect fit for your Luna are the ones that we create :)
Weighted Blankets are designed to cover your body and not a larger surface area, because we want the weight to rest on your body and not your entire bed! That would affect which weight to choose and make things very confusing!
We have standard sizes available, but they're generally meant to only cover the top of your bed, so they will not hang off the edges. All blankets will be approximately the measurements you see in our Size Guide. It's not abnormal to see a blanket that's .5-1 inch off in size or .5-1 pound off in weight.
