Split California King is the size most bedding brands don't even attempt. If your adjustable base needs the extra length a Cal King gives you, you've probably already found out that a standard Split King sheet is 4 inches too short — and a pair of Twin XL sets doesn't match your mattress width.
The Split Cal King Bamboo Sheet Set is cut specifically for this bed: two separate 36" x 84" fitted sheets, one per side, so each half of your base moves independently without stretching, pulling, or dragging the other side out of place.
Every Complete Sleep Bundle includes:
- 1 Split Cal King Bamboo Sheet Set — 2 fitted sheets (36" x 84", one per side), 1 flat sheet (110" x 104"), and the 4 matching King pillowcases that already ship with the set
- 1 Adjustable Bamboo Cooling Pillow, King — an inner zipper lets you add or remove shredded gel-infused memory foam fill until the loft matches your side of the bed
Both pieces carry the track record BiB's flagship products have already earned: the Signature Sheet Set this fitted sheet is cut from holds 4.87★ from 261 verified reviews; the Adjustable Cooling Pillow holds 4.76★ from 124. Viscose from bamboo, OEKO-TEX Standard 100 certified, tested to sleep 3x cooler than cotton, made using 70% less water to produce than cotton.
Separately, the sheet set and pillow run $418. Together, this bundle is $349 — $69 less, built into the price, no code required. Backed by a 30-night sleep trial, free shipping, and a 1-year warranty on both pieces.
