I was skeptical but this is amazing! Typically, “deep” fitted sheets aren’t actually all that deep and end up slipping off my mattress pretty quickly. This one genuinely is deep though. It fully covers my mattress and actually extends under my mattress a fair bit too. I’m thoroughly pleased! Also the material is quite soft and comfy. Too early yet to tell how it wears (pilling and tearing) but I have high hopes. If you’re in need of a deep fitted sheet, I highly recommend this one!
