If you have a California king mattress with a pillow top, topper, or other added depth, pocket size matters as much as softness. The best bamboo sheets for your bed should match its 72-by-84-inch dimensions, stay secure around the corners, and feel comfortable in your usual sleep climate. These five sets are made from bamboo-derived viscose or rayon, but their pocket depths and set details differ—so measure your mattress before choosing.
| Sheet set | Fitted-sheet pocket | Notable feature | Best fit for |
|---|---|---|---|
| SONORO KATE 100% Viscose Bamboo Sheets | 18–24 inches | Extra-deep pocket with 360-degree elastic | Very deep mattresses |
| California Design Den Bamboo Sheets | Up to 18 inches | All-around gripper elastic and envelope pillowcases | Hot sleepers with mattresses up to 18 inches |
| DOZ by SIJO Bamboo Sheet Set | 16 inches | 145 GSM fabric and choice of set configuration | Those who want a lighter set with a 16-inch pocket |
| DREAMCARE Bamboo Sheets | 16 inches | OEKO-TEX certification | Shoppers who want a straightforward four-piece set |
| Sasttie Bamboo Sheet Set | 16 inches | Corner straps and a head-orientation tag | Those who value extra fitted-sheet details |
Our Picks: Best Bamboo Sheets Cal King Deep Pocket reviews
1. SONORO KATE: Best for Extra-Deep California King Mattresses
The SONORO KATE set stands out for its 18-to-24-inch fitted-sheet pocket, the deepest range in this group. That extra room makes it the strongest option here for a California king mattress with a thick pillow top, a substantial topper, or other added layers. Its fitted sheet is sized 72 by 84 inches, and the set includes a flat sheet and two pillowcases.
The fabric is described as 100% viscose derived from bamboo, with a smooth feel and moisture-wicking properties. A 360-degree elastic band is designed to help the fitted sheet grip the mattress. That combination of generous pocket depth and elastic around the full edge is useful when a standard fitted sheet tends to pull loose at the corners.
The trade-off is that its unusually deep pocket may be more fabric than you need on a thinner mattress. The product description also does not provide a thread count or a fabric weight, so shoppers who want to compare those specifications will have less detail to go on. Follow the stated care instructions—cold wash and low tumble dry—to help care for the fabric.
Pros:
- Fits mattresses listed as 18 to 24 inches deep.
- Includes a 360-degree elastic edge for a more secure fit.
- California king fitted-sheet dimensions are 72 by 84 inches.
- Machine washable and dryer friendly, according to the product details.
Cons:
- May have more pocket depth than needed for a thinner mattress.
- The product details do not specify fabric weight or thread count.
Verdict: Choose SONORO KATE if your California king mattress measures more than 18 inches deep or you want the widest fit range in this selection.
2. California Design Den: A Silky Option for Mattresses Up to 18 Inches
California Design Den offers a four-piece set made from 100% viscose from bamboo. The fitted sheet is designed for mattresses up to 18 inches deep, putting it between the extra-deep SONORO KATE and the 16-inch-pocket options in this guide. Its all-around gripper elastic is intended to help the sheet stay in place.
The set includes a 108-by-104-inch flat sheet, a 72-by-84-inch fitted sheet, and two pillowcases sized for king pillows. The pillowcases have envelope closures, while top-and-bottom tags on the fitted sheet help you orient it during bed-making. The company describes the fabric as silky and cooling, and notes that it has been tested for pilling, shrinkage, and fading.
This set is a sensible middle ground if your mattress is no deeper than 18 inches and you want a smooth, drapey fabric. It is not the best match for mattresses that exceed the stated depth, and the product information specifically says it is for one California king mattress, not a split king. The silky finish also will not suit everyone; shoppers who prefer crisp percale should consider another type of fabric.
Pros:
- Designed to fit mattresses up to 18 inches deep.
- All-around gripper elastic and orientation tags add practical details.
- Envelope closures help keep pillows tucked inside their cases.
- OEKO-TEX STANDARD 100 tested, according to the product details.
Cons:
- Not intended for a split California king setup.
- The silky feel may not appeal to people who prefer crisp cotton percale.
Verdict: Pick California Design Den for a silky bamboo-derived set with useful bed-making details, provided your mattress is 18 inches deep or less.
3. DOZ by SIJO: A Higher-GSM Set with Flexible Set Choices
DOZ by SIJO makes its sheets from 100% viscose derived from bamboo grown on organically grown farms, according to the product description. Its 145 GSM fabric is heavier than many sheets, while the sateen weave and 300-thread-count finish are intended to create a smooth drape. The fitted sheet has a 16-inch pocket, so measure carefully if your mattress has a topper or a tall pillow top.
One useful difference is the choice between a three-piece core set and a four-piece set with a flat sheet. The core option includes a fitted sheet and two envelope-style pillowcases; the larger configuration adds a flat sheet. This lets you skip the flat sheet if you use a duvet and prefer not to have an extra layer.
The fabric is described as breathable and moisture-wicking, making it worth considering if you tend to sleep warm. Its 16-inch pocket is less generous than the SONORO KATE or California Design Den options, however. For care, the product details recommend a cold gentle wash and low tumble dry, and advise against fabric softener and dryer balls.
Pros:
- Offers a choice of a three-piece or four-piece set.
- 145 GSM fabric provides a specific weight detail for comparison.
- OEKO-TEX Class 1 certified, according to the product description.
- Envelope-style pillowcases have overlapping closures.
Cons:
- The 16-inch pocket may not fit a thicker mattress or topper combination.
- Care instructions call for avoiding fabric softener and dryer balls.
Verdict: DOZ is a strong choice if your mattress is 16 inches deep or less and you want to choose whether your set includes a flat sheet.
4. DREAMCARE: A Simple Four-Piece Set with a 16-Inch Pocket
DREAMCARE’s California king set is made from 100% rayon derived from bamboo. It includes a 72-by-84-inch fitted sheet with a 16-inch pocket, a 106-by-102-inch flat sheet, and two pillowcases. The listed dimensions make the set easy to compare with your existing bedding, while the pocket depth gives you a clear limit to check against your mattress.
The company describes the fabric as silky and breathable and lists it as 240 thread count. It is also OEKO-TEX certified, according to the product information. The set is machine washable, making it a straightforward option for shoppers who want a complete set without many special design details.
Its main limitation is fit: a 16-inch pocket can be too shallow for a tall mattress or a thick mattress-and-topper combination. Compared with DOZ, DREAMCARE does not list a fabric weight or an option to purchase the set without a flat sheet. Consider it if those details matter less to you than getting the basic four pieces in one package.
Pros:
- Includes a flat sheet, fitted sheet, and two pillowcases.
- California king fitted-sheet dimensions are 72 by 84 inches.
- OEKO-TEX certified, according to the product description.
- Machine washable for routine care.
Cons:
- The fitted sheet is designed for mattresses up to 16 inches deep.
- Set configuration is not listed as customizable.
Verdict: Consider DREAMCARE if your mattress is 16 inches deep or less and you want a simple, complete set with stated certification details.
5. Sasttie: A 16-Inch-Pocket Set with Corner Straps
Sasttie’s set uses 100% rayon made from bamboo and has a 300-thread-count construction. Its fitted sheet is 72 by 84 inches with a 16-inch pocket. A 360-degree elastic edge and four built-in corner straps are intended to help secure the sheet and limit shifting.
The set includes a flat sheet, fitted sheet, and two pillowcases. Small conveniences include a tag to help identify the head of the fitted sheet and envelope closures on the pillowcases. The product description also lists OEKO-TEX STANDARD 100 certification and recommends a cold gentle wash followed by low-heat drying.
Like the other 16-inch-pocket sets here, Sasttie is not the right choice for a mattress that exceeds that depth once any topper is included. Its extra corner straps may be useful if you want more than an elastic edge, but they do not make the pocket deeper. The dark-grey set is also described as coming in gift-ready packaging, which may be a bonus if you are shopping for a present.
Pros:
- Four corner straps work alongside the full elastic edge.
- Head tag helps with fitted-sheet orientation.
- Envelope pillowcases and a 300-thread-count construction are specified.
- OEKO-TEX STANDARD 100 certified, according to the product details.
Cons:
- The 16-inch pocket is not suited to deeper mattresses.
- Care instructions recommend washing separately and avoiding a hot dryer.
Verdict: Choose Sasttie if your mattress fits within the 16-inch pocket and you value corner straps and practical sheet-orientation details.
How to Choose Bamboo Sheets for a California King with Deep Pockets
Measure your mattress, including any topper
Measure from the bottom edge to the top of the mattress, including a pillow top or topper that will stay on the bed. A fitted sheet needs enough pocket depth to cover that full height and tuck securely underneath. Of these picks, SONORO KATE has the largest stated range at 18 to 24 inches; California Design Den fits up to 18 inches; and DOZ, DREAMCARE, and Sasttie list 16-inch pockets.
Confirm the California king dimensions
A standard California king mattress measures 72 by 84 inches, and each fitted sheet in this guide lists those dimensions. Check the product details before ordering, especially if your bed is a split setup. California Design Den specifically identifies its set as being for one California king mattress rather than a split king.
Choose the feel and fabric details you prefer
All five options use bamboo-derived viscose or rayon. The product descriptions emphasize a smooth or silky feel, and some describe moisture-wicking or cooling properties. Those details can help you narrow your choices, but they do not guarantee that every sleeper will feel the same way. If you prefer crisp, textured bedding, a silky fabric may not be your ideal match.
Compare the fitted-sheet features
Elastic and extra fit features can make a difference when you change sheets or move around in bed. SONORO KATE lists a 360-degree elastic band, California Design Den has all-around gripper elastic, and Sasttie adds four corner straps. These features may help with a secure fit, but pocket depth remains the key factor: added straps will not compensate for a sheet that is too shallow.
Check what comes in the set
Most options here include a flat sheet, a fitted sheet, and two pillowcases. DOZ also offers a three-piece configuration without the flat sheet, which can be useful if you use a duvet instead. Compare the listed pillowcase and flat-sheet sizes with your pillows and bed before ordering.
Read care instructions before you buy
These sets are listed as machine washable, but the recommended care varies. Several call for cold washing and low-heat drying, while DOZ advises against fabric softener and dryer balls. Follow the instructions for the specific set you choose, and remove sheets promptly from the dryer when the product details recommend it.
Frequently Asked Questions
What pocket depth do I need for a California king mattress?
Measure the mattress from its base to its top, including any topper or pillow top that stays on the bed. Choose a fitted sheet whose stated pocket depth covers that measurement with enough fabric to tuck under the mattress. If your mattress is between 18 and 24 inches deep, SONORO KATE is the only pick here with that listed range.
Which set has the deepest pockets?
SONORO KATE lists an 18-to-24-inch pocket. California Design Den fits mattresses up to 18 inches deep, while DOZ, DREAMCARE, and Sasttie list 16-inch pockets.
Are all of these sheets made from bamboo?
They are described as viscose or rayon derived from bamboo. That wording refers to the fabric fiber used in the sheets; check each product’s material details if you have a specific preference or need to confirm a label.
Which set is best for a hot sleeper?
Several product descriptions highlight cooling, breathability, or moisture-wicking features, including California Design Den, DOZ, DREAMCARE, and Sasttie. Those features may be appealing if you sleep warm, but personal comfort can vary. Choose a set that also fits your mattress depth and care preferences.
Can I use these sheets on a split California king bed?
Check the listing carefully before buying. California Design Den specifically says its set is for one California king mattress, not a split king. The supplied details for the other sets do not clearly confirm split-bed compatibility.
Do bamboo-derived sheets need special care?
Care instructions differ by set, but several recommend cold water and low-heat drying. DOZ also advises against fabric softener and dryer balls. Follow the instructions for the exact set you purchase to care for the fabric as directed.
Final Recommendation
For a genuinely deep California king mattress, SONORO KATE is the clearest choice because its fitted sheet is designed for mattresses from 18 to 24 inches deep. If your mattress is 18 inches or less, California Design Den offers a useful middle ground with all-around gripper elastic and envelope pillowcases. For mattresses no deeper than 16 inches, compare DOZ, DREAMCARE, and Sasttie based on the set configuration and fitted-sheet features you prefer.
