FAQ's
What is a Split Top King sheet?
Split Top King sheets (also called Flex Top King sheets) are made for mattresses where the top portion is split but the bottom remains connected. This lets each person adjust their head independently on an adjustable base.
What’s the difference between Split King and Split Top King?
A Split King is typically two Twin XL mattresses side-by-side, while a Split Top King is one mattress with only the top portion split. This difference affects the type of fitted sheet you need.

Do these sheets fit deep mattresses?
Yes. The fitted sheet is designed for mattresses up to 16" deep.
What are the 1800 Series sheets made from?
They’re made from premium microfiber, selected for softness, durability, wrinkle resistance, and easy care.
Are these compatible with Sleep Number beds?

Do you offer bundle pricing?
