I can't recommend this sheet highly enough. We have a very deep mattress with a memory foam mattress topper as well so altogether the depth is about 16 inches. I've bought quite a few 16 inch fitted sheets recently from different suppliers and they all fit well enough but I've found after a night or two the corners do tend to come loose and I'm forever tucking it back under again. However with this one I haven't had that problem at all. If you're looking for a deep well fitting sheet, I don't think you'll go wrong with this one.
I will definitely be buying more of these sheets! Since buying a new deeper mattress I've struggled with our current sheets as they just ping off. These sheets are deeper so they fit perfectly and they feel nice too. The price is good too! Thank you!
My mattress with topper is 12 inches deep and I am fed up with most shops not stocking deep enough fitted sheets (especially after they have been washed a couple of times). This product is actually slightly too big if anything, but will probably fit perfectly after a few washes. It is also very soft. Only slight disappointment is that it is not quite as "easy care" as I expected and really needs ironing, but who has time to iron sheets!
