i loveee this blanket. after opening and breaking the air seal i threw it in the dryer for 20 minutes to fluff it up and it's perfect. it's very thick and slightly weighted (3-5 lbs) and super duper stretchy. it's double sided so you can use it facing any way you want. i've never tried either brands but from everything i've seen, this is pretty much an exact duplicate to the lola brand and comfrt brand blankets. i do wish they made more size and color options but other than that i'm obsessed. (for size comparison reference, i have a queen bed!)
