I ordered the largest size, all seem to have the same issue when looking to order one. It spreads but does Not come up high on neck or to feet! If I can’t tuck foot blanket under mattress I like it to at least go to cover feet  shoulders and find it does not! The size creates issues with the weight and quite often wake up and it has slid off the bed or partially as it is not wide enough over the sides of the mattress and I only have a twin bed but ordered the largest blanket available!
