While American bed sizes have remained fixed, there are no standard mattress depths. As a general rule, our fitted sheets have a gusset (AKA “pocket size” or “pocket depth”) that will fit mattresses up to 17” deep with enough room to tuck under the mattress. However, most of our purveyors accommodate custom orders for deeper or thinner sizes.

Don't feel that you have to stick to the materials on this list. I just finished testing the Naturalmat Organic Hemp Bed Linen Collection, and I can't stop talking about this miracle material. Hemp combines all the best bits of linen, in terms of breathability and durability, and it's that little bit softer to suit sensitive sleepers. If you're looking for something more luxurious, the Shleep Luxury Merino Wool bedding set could be right up your street.
