Bamboo vs. cotton
Three reasons hot sleepers switch
01
Sleeps up to 3× cooler
Bamboo viscose wicks heat and moisture away instead of trapping it — so the bed never turns into a sauna at 2am.
02
Silk-soft, gets softer
A naturally smooth fiber with none of the heavy, hot hand of cotton — and it softens with every wash.
03
Naturally cleaner
Naturally hypoallergenic and breathable, grown with ~70% less water than cotton. Kind to sensitive skin and the planet.

The weave
Buttery-soft, naturally cool
Woven from 100% viscose (rayon) from bamboo in a smooth, buttery-soft sateen weave — the close, lustrous finish that gives these sheets their cool, silky hand. Lightweight and breathable, the fabric moves heat and humidity away as you sleep, so it sleeps up to 3× cooler than cotton (Bamboo Is Better testing). Naturally hypoallergenic and gentle against sensitive skin.

Good to know
Questions, answered
What makes these sheets cooling?
Our Signature sheets are woven from breathable bamboo viscose, so they move heat and humidity away from your skin as you sleep instead of trapping it the way cotton can. In our own testing they sleep up to 3× cooler than cotton — which is why they're made for the body that runs hot.
What's included in the Split Cal King set?
Every Split Cal King set is complete: two fitted sheets (36″ × 84″, one per side), one flat sheet (110″ × 104″), and four King pillowcases (20″ × 36″). The fitted sheets are cut for the extra length a California King gives you, so each side articulates on its own.
Will these fit my mattress and adjustable base?
Yes. The fitted sheet has a 15-inch deep pocket with all-around elastic, and the reinforced corner straps stretch to grip mattresses up to 18 inches deep — standard, pillow-top, or topper on top — so it stays put through the night. We also make sizes built for adjustable bases — Split Queen, Split King, Split Cal King, and Top Split King — so you get sheets that actually fit your setup. Check the size guide to match your mattress.
What if they're not right for me?
Sleep on them for 30 nights. If they're not your favorite sheets, send them back and we'll refund your order, minus a small return fee ($14.99 or 3% of the order total, whichever is greater). The whole point of the 30-night sleep trial is to let you decide in your own bed, not in a store.
How fast do they ship, and is shipping free?
Shipping is free on all orders within the continental US. Orders to Alaska, Hawaii, and international destinations are not free — shipping is calculated at checkout. Most orders ship within about one business day, with 3 to 5 days in transit after that.
Are they safe and free of harmful chemicals?
Yes. Our Signature sheets are OEKO-TEX Standard 100 certified, which means the fabric has been independently tested for harmful substances. The bamboo viscose is also naturally hypoallergenic and gentle against sensitive skin.
How do I care for them, and are they guaranteed?
Care is simple: machine wash cold on a gentle cycle, tumble dry low or hang to dry, and skip bleach, fabric softener, and ironing. They're backed by a 1-year warranty that covers manufacturing defects — including pilling under normal care — with a replacement.
Why did my bamboo sheets stain?
Bamboo is a naturally absorbent fiber — part of what makes it feel cool and breathe so well — so it can pick up face and body oils, lotions, and hair and skincare products more readily than a synthetic blend. Those oils can soak in and leave a dark, splotchy mark, usually around the pillow. It's how the fiber behaves, not a defect.
A couple of things keep it from happening: wash your sheets before the first use, and head to bed with clean, dry skin and hair so lotions and oils have time to absorb. One thing to watch — benzoyl peroxide in acne products can bleach color out of sheets and pillowcases (any brand, any colored bedding), so let it dry fully before bed or use a dedicated white pillowcase.
If a stain does happen, treat it fresh: blot, rinse with cold water, work in a little grease-cutting dish soap or an enzyme-free remover, and air-dry — never tumble-dry until the mark is fully gone, since heat sets it.
