The Best Bamboo Sheets for Adjustable Beds
The best bamboo sheets for an adjustable bed are Bamboo Is Better’s Signature Sheet Set in a split size — Split King, Split Cal King, Top Split King, or Split Queen — so each side of the base moves independently without pulling the sheet loose. They’re moisture-wicking viscose from bamboo, OEKO-TEX Standard 100 certified, tested to sleep up to 3× cooler than cotton, with corner straps that fit mattresses up to 18″ deep. Most brands don’t make these sizes — Bamboo Is Better stocks all four. Backed by 252 reviews at 4.90★, a 60-night trial, free returns, and a 3-year warranty.
Why adjustable beds need a split sheet
An adjustable base raises each side independently — so a single one-piece sheet binds, untucks, and pops a corner the first time one side lifts. A split sheet solves it: the top is split down the middle (or supplied as two pieces) so each half moves with its side of the bed. The trade-off most shoppers don’t know: you match the split size to the base, not just the mattress. A King adjustable base that splits into two Twin XL halves takes a Split King; a Cal King base takes Split Cal King; if only the head splits, that’s Top Split King.

Why bamboo on an adjustable bed
- Up to 3× cooler than cotton — adjustable-base sleepers are often hot sleepers; viscose from bamboo wicks and breathes where cotton traps heat.
- OEKO-TEX Standard 100 certified — tested for 100+ harmful substances; certificate available on request. See our OEKO-TEX certification page.
- The sizes nobody else stocks — Top Split King especially: almost no competitor makes it.

Frequently asked questions
What size bamboo sheets do I need for an adjustable bed?
A split size — Split King, Split Cal King, Top Split King, or Split Queen — so each side of the base moves independently without untucking the sheet.
What’s the difference between Split King and Top Split King?
A Split King has the whole top split into two Twin XL halves so both sides articulate. A Top Split King splits only the head, with a single one-piece foot, for bases where just the head raises.
Do bamboo sheets fit deep adjustable mattresses?
Yes — Bamboo Is Better fitted sheets have corner straps that secure mattresses up to 18″ deep, which covers the thicker mattresses used on most adjustable bases.

Yes — they’re the same viscose-from-bamboo fabric tested to sleep up to 3× cooler than cotton, moisture-wicking and OEKO-TEX Standard 100 certified.
