These are by far the softest flannel sheets I’ve ever owned...but I gave only 4 stars because they don’t fit well on the king sized bed, which doesn’t exactly have a big depth to it. So it’s really for a small king sized bed or may’ve would go better on a mattress cover even. I slept in the sheets last night and oh my goodness, I didn’t want to get out of bed. Perfect for if you need to keep the heat low or like cool air while being snuggly warm under the covers. Definitely worth it—just grab some sheet straps with them!
