A bamboo bed set king is a king-size bedding set woven from bamboo-derived viscose, typically including a fitted sheet, flat sheet, and two pillowcases.
If you’ve been shopping for softer, cooler bedding, you’ve likely seen the term. A bamboo bed set king refers to a complete bedding package sized for a standard king mattress, not a bed frame or mattress itself. The draw is the fabric: bamboo viscose sheets are known for temperature regulation and a silky feel that gets softer with each wash.
What actually arrives in the box varies by brand, and sizing isn’t fully standardized. Here’s what to expect, how to check fit, and what to look for before you buy.
The Standard Pieces in a King Bamboo Sheet Set
Most king bamboo sheet sets follow a familiar formula. You get the three essentials for a king bed, sometimes with extras.
- Fitted sheet — sized for a standard king mattress, usually 78″ x 80″
- Flat sheet — typically around 110″ wide by 106–114″ long
- Two pillowcases — standard king size, about 20″ x 38″ to 40″
Some bundles go further, adding a duvet cover and pillow shams. Cariloha’s king sets, for example, stick to the core four pieces, while their deluxe bedding configurations bundle additional items at higher price points.
How Bamboo King Set Sizing Varies by Brand
Mattress depth is where most fit problems happen. A king fitted sheet needs to wrap a mattress that can range from 10 inches to over 20 inches thick.
Cariloha’s product pages state their king fitted sheets stretch to fit mattresses up to 20 inches deep. That generous pocket handles most pillow-top and deep-pocket mattresses on the market. Don’t assume every brand offers that range though — some bamboo king sets only fit mattresses up to 16 inches deep, so checking the listed pocket depth is essential before ordering.
| King Set Component | Common Measurement | Fit Notes |
|---|---|---|
| Fitted sheet | 78″ x 80″ | Pocket depth ranges from 16″ to 20″ by brand |
| Flat sheet | 110″ x 106–114″ | Generous drape on standard king beds |
| Pillowcases (2) | 20″ x 38–40″ | Fits standard king pillows |
If your mattress is deeper than 20 inches — some luxury hotel-style mattresses run 22 inches or more — look for a set that explicitly states its max depth rather than assuming it will work.
Materials, Safety, and Care for Bamboo Viscose Sets
When brands say “bamboo,” they almost always mean viscose derived from bamboo pulp. The manufacturing process transforms bamboo fibers into a soft, breathable fabric that feels closer to silk or high-end cotton than to rough natural linen. Products are commonly labeled 100% bamboo viscose or 100% viscose from organic bamboo.
Quality varies, so independent certifications help separate genuine products from marketing claims. Cariloha’s sets are OEKO-TEX Standard 100 certified, meaning the fabric was tested and found free from over 100 potentially harmful substances. That certification matters if you have sensitive skin or want assurance about what’s touching your family all night.
Care instructions are straightforward but specific. Machine wash bamboo sheets in cold water on a delicate cycle. Use a mild, liquid detergent free from dyes, perfumes, and added stain lifters — those additives can break down bamboo fibers over time. Skip fabric softener; it coats the fibers and reduces breathability.
California King and Split King Differences
A standard king and a California king are not interchangeable. California king mattresses are longer and narrower, so a standard king fitted sheet won’t fit properly.
Some bamboo sheet brands offer California king versions of their sets, and a smaller number produce split king configurations for adjustable beds. If you sleep on an adjustable base or a split king setup, confirm the set you’re considering comes in that specific size before purchasing.

Price is another variable worth noting. A quality king bamboo set typically lands between $200 and $300 at regular price, though larger bundle configurations can climb to $400 to $600 or more depending on how many pieces are included.
FAQs
How many pillowcases come in a bamboo king sheet set?
Standard king bamboo sheet sets include two king-size pillowcases sized around 20″ x 38″ to 40″. Some premium bundles add a duvet cover and extra shams, which increases both the piece count and the overall price.
Will bamboo sheets fit a deep-pocket mattress?
It depends on the brand. Cariloha’s king fitted sheets stretch to accommodate mattresses up to 20 inches deep, while other manufacturers limit fit to 16 inches. Check the listed pocket depth before buying if your mattress is thicker than average.
Are bamboo sheets better than cotton for hot sleepers?
Bamboo viscose sheets are generally more breathable and moisture-wicking than standard cotton, which helps regulate temperature during sleep. They also have a silkier feel that many hot sleepers prefer, though high-quality long-staple cotton remains a strong alternative.
