The wrong size ruins a good sheet set. Here's everything you need to know — bed dimensions, pocket depths, and what to do if you have an adjustable base.

Deep pockets, built to stay put. Our fitted sheets have a 15″ pocket on the Signature collection and a 16″ pocket on the Premium collection — and the elastic corner straps stretch to hold mattresses up to 18″ deep, including pillow-tops and toppers. No more sheets popping off in the night.
How to measure your mattress
- Measure your mattress length × width × height.
- Match the length × width to your size in the table above.
- Check the height: Signature fits up to a 15″ mattress, Premium up to 16″ — and the corner straps stretch to fit up to 18″ deep, covering most pillow-tops. Deeper than 18″? Contact us before ordering.
Specialty & split sizes
Sleep on an adjustable base? You probably need a split size — built for two mattresses side by side, or a single mattress that bends at the head. Most brands don't even explain these. We stock all four and make it simple.
| Size | What it is | Who it's for |
|---|---|---|
| Split King | Two Twin XL mattresses side by side — 38″ × 80″ each (76″ × 80″ total) | Couples with a King-size adjustable base; each side moves independently |
| Split Cal King | Two extra-long mattresses side by side — 36″ × 84″ each (72″ × 84″ total) | Couples with a California King adjustable base |
| Top Split King | One King fitted sheet (76″ × 80″) split only at the head end, solid across the bottom | King adjustable bases where the head section raises independently |
| Split Queen | Two narrow mattresses side by side — 30″ × 80″ each (60″ × 80″ total) | Couples with a Queen-size adjustable base |
What comes in each specialty set
- Split King: 2 Twin XL fitted sheets + 1 King flat sheet + 4 King pillowcases
- Split Cal King: 2 extra-long fitted sheets + 1 Cal King flat sheet + 4 King pillowcases
- Top Split King: 1 specialty fitted sheet (split head, solid base) + 1 King flat sheet + 4 King pillowcases
