If you and your partner sleep on an adjustable bed, you already know the problem: the moment one side lifts up, an ordinary fitted sheet pops off the corner. A top split sheet set solves this. It is designed so each side of the bed can move independently while the sheets stay put, which is exactly what a split-head adjustable base needs.
A top split sheet set has a fitted sheet that is split at the top so each side moves on its own, plus a flat sheet and pillowcases. It is made for split-head adjustable beds. Ours comes in Queen, King and California King, from $63.99.
What is a top split sheet set?
A top split sheet set is a full set built around a specially cut fitted sheet. Instead of one solid piece of fabric across the whole mattress, the fitted sheet is divided from the top down to about the middle, so the two halves of the bed can be raised separately without pulling the sheet loose. The split is what makes it work on a split-head adjustable bed, where each person can recline their own side.
Alongside the split fitted sheet, our set includes a flat sheet and matching pillowcases, so you get everything you need in one purchase. The split section usually has extra fabric overlap so the gap does not gape open when the bed is flat.
Who needs a top split sheet set?
You need a top split sheet set if any of these describe your bed:
- Split-head adjustable base. The top third of each side lifts separately for reading, watching TV or easier breathing. This is the classic case.
- Two separate adjustable mattresses. Many King and Cal King adjustable sets are really two twin-XL bases side by side. A top split sheet keeps them looking like one bed.
- Partners with different sleep positions. If one of you elevates and the other lies flat, a normal fitted sheet fights you every night. The split ends that.
If your bed is a standard flat mattress, you do not need a split sheet. A regular deep pocket sheet set is the right choice there.
Sizes, pockets and pricing
Our top split sheet set comes in the three sizes that adjustable beds usually use, with a choice of pocket depth so it fits thicker mattresses and toppers. Here is the real range:
| Size | Pocket depth | From |
|---|---|---|
| Queen | 15" or 18" | $74.99 |
| King | 15" or 18" | $83.99 |
| California King | 15" or 18" | $75.99 |
The 32" split length is standard across the sizes, which matches the split section on most adjustable bases. If you are unsure, measure how far down your bed splits before ordering.

Frequently asked questions
What is the difference between top split and split king?
They describe the same idea. A top split (also called split-head or flex-top) is split only at the top so the halves lift separately, while the bottom stays joined so the bed still feels like one surface. A fully split king is two separate mattresses with no join.
Will a top split sheet work on a regular bed?
It will fit, but the split is unnecessary on a flat mattress and you may notice the seam. For a standard bed, a regular fitted sheet set is the better buy.
How do I measure for a top split sheet?
Check your mattress size (Queen, King or Cal King), the mattress depth including any topper, and how far down the adjustable base splits. Match those to the size and pocket depth options.
Do both sides stay tucked when the bed is raised?
Yes. The split fitted sheet plus 360-degree elastic keeps each side gripped to its own half, so nothing pops off when you elevate.
