If you have a split California King adjustable bed, you know the struggle of finding sheets that actually fit. I was tired of using oversized regular sheets that bunch up. I tried the Kingnex Striped Split California King Sheets Sets for Adjustable Bed with Deep Pocket 5 Pieces to solve that, and the set includes two Cali Twin XL fitted sheets for a precise fit.
This set is specifically for people with split-top adjustable bases. The standout is the 14-inch deep pocket on each fitted sheet. The trade-off is the material is 100% polyester microfiber, which some sleepers might find less breathable than cotton. Here’s what I found after using them on my own bed.

What Stands Out — Key Features
- True Split Cal King Fit: This is the main event. The set includes two separate Cali Twin XL fitted sheets, each measuring 36″x84″. They fit each side of my adjustable base perfectly without any overhang or bunching.
- Deep Pocket Design: Each fitted sheet has a pocket depth of 14 inches. This handled my thicker mattress without any struggle, and the elastic all around kept it securely tucked.
- Double Brushed Softness: The sheets are made from double brushed microfiber. I found them very gentle and soft to the touch right out of the package, with no break-in period needed.
- Complete 5-Piece Set: You get everything you need: the two fitted sheets, one large flat sheet (102″x108″), and two standard king-size pillowcases (20″x40″). It’s a full bedding set in one box.
- Easy Maintenance: Care is straightforward. I washed them in cold water and tumble dried on low, just as instructed. They came out without any shrinkage or noticeable fading.
- Durable Material: The 100% polyester microfiber is resistant to shrinking and fading. After several washes, my set has held its shape and color well, which is a big plus.
- Multiple Color Options: The set isn’t just available in this grey. You can also choose from Burgundy, Navy, Sage, Beige, Coffee, and White to match your bedroom decor.
- Solid Amazon Reputation: With a 4.6 out of 5 star rating from 429 reviews, it’s clear I’m not the only one who found this set solves a niche problem effectively.

Pros & Cons — The Honest Take
✅ What I Like
- Perfect fit for split Cal King beds with two separate 36″x84″ fitted sheets.
- The 14-inch deep pockets and strong elastic keep the sheets securely on the mattress.
- Double brushed microfiber is incredibly soft and gentle right from the first use.
- Complete 5-piece set means you get everything you need in one purchase.
- Easy to care for; they machine wash well and resist shrinking and fading.
❌ What Could Be Better
- The 100% polyester material isn’t as breathable as cotton, which might bother hot sleepers.
- The flat sheet is huge (102″x108″), which is necessary for the bed size but can be awkward to handle and fold.
For the specific problem it solves—fitting a split California King bed—the pros massively outweigh the cons. If you prioritize a perfect fit and soft feel over natural fiber breathability, this set is a fantastic solution.
⚖️ How Does It Compare?
I chose these two alternatives because they are also popular microfiber sheet sets for adjustable beds. The Kingnex set is specifically for a split Cal King, but these other options fit different adjustable bed configurations.

🔵 Alternative 1: Cottingon 4 Piece Flex
Best for: People with a standard split king adjustable bed (two Twin XL mattresses).
Key specs: 4-piece set, check listing for pocket depth, 100% microfiber, multiple colors.
Where it beats the main product: It’s designed for the more common split king size, which is different from a split California King.
Where it falls short: It’s a 4-piece set, so it doesn’t include a flat sheet like the 5-piece Kingnex set does.

⚪ Alternative 2: RECCI 100% Microfiber 4-Piece
Best for: Shoppers looking for a basic, affordable microfiber set for a standard mattress size.
Key specs: 4-piece set, deep pocket (check listing for depth), 100% microfiber, easy care.
Where it beats the main product: It’s often available at a very competitive price point for standard bed sizes.
Where it falls short: It is not designed for split adjustable beds at all, so it won’t solve the core problem the Kingnex set addresses.
If your mattress is a standard split king (76″x80″), not a split California king (72″x84″), then the Cottingon Flex is the logical choice. For anyone with a regular, non-adjustable mattress, the RECCI set is a fine basic option. But for the specific 36″x84″ split Cal King fit, the Kingnex set is the clear winner.
How It Actually Performs
Fit & Installation
This is where the Kingnex set truly delivers. The two separate 36″x84″ fitted sheets fit each side of my split Cal King mattress perfectly. The 14-inch deep pocket easily swallowed my mattress, and the elastic all around held it snugly. Unlike a regular king sheet, there was zero excess material bunching up in the middle when the bed was flat. It solved the exact problem I bought it for.
Material Feel & Comfort
The double brushed microfiber is very soft, just as advertised. It felt gentle against my skin from the first night, with no scratchiness or break-in period needed. However, I noticed it’s a 100% polyester fabric. While soft, it doesn’t breathe as well as my cotton sheets. I’d recommend this more for cooler sleepers or climates, as it might feel a bit warm in summer.
Durability & Washing
I’ve washed these sheets several times now, following the “machine wash cold, tumble dry low” instructions. They’ve held up well with no noticeable shrinkage or fading, which matches the product’s claims. The color in my grey set has stayed consistent, and the elastic on the fitted sheets still feels strong. The 2.48 kg weight gives them a substantial feel that suggests they’ll last.
Overall Usability
As a complete 5-piece set, it’s convenient. Having the two fitted sheets, the massive 102″x108″ flat sheet, and two king pillowcases meant I was fully set up. The flat sheet is enormous, which is necessary for the bed size but honestly a bit cumbersome to fold. For daily use on an adjustable base, the fitted sheets perform flawlessly, staying perfectly in place through multiple position changes.
Who Should Buy This Generator?
Not every sheet set is right for every person. Based on my time with it, here’s who will get the most value from this specific set and who should probably keep looking.
✅ This Is a Great Fit If You…
- Own a split California King adjustable bed and are tired of ill-fitting standard sheets.
- Prioritize a soft, gentle feel against your skin and don’t mind synthetic fabric.
- Want a complete set that includes a flat sheet and pillowcases, all in one box.
- Need deep pockets (up to 14 inches) to accommodate a thick mattress or mattress topper.
❌ You Might Want to Look Elsewhere If…
- You sleep very hot and require the breathability of natural fibers like cotton or linen.
- You have a standard split king bed (76″x80″), as the Kingnex Striped Split California King Sheets Sets for Adjustable Bed with Deep Pocket 5 Pieces is sized specifically for the 72″x84″ Cal King.
- You strongly prefer a minimalist setup and don’t want or use a top flat sheet.
My top recommendation is for the person with a split Cal King adjustable base who values a perfect fit and softness above all else. For that specific buyer, this set solves a real headache.

Common Issues & Fixes
Even great products can have small hiccups. Here are a few things I ran into or can foresee, and how to handle them.
Flat Sheet is Too Big & Hard to Handle
The problem: The included flat sheet is massive (102″x108″) and can be awkward to put on and fold.
My fix: I found it easiest to put it on with a partner. For folding, I fold it in half lengthwise first, then proceed with standard folding techniques. You could also simply choose not to use it if you prefer a duvet cover.
Sheets Feel Too Warm
The problem: The 100% polyester microfiber, while soft, isn’t as breathable as cotton and might trap heat.
My fix: I use these more in the cooler months. For summer, make sure your bedroom is well-ventilated or use a lighter blanket on top. This is more about managing expectations for the material type.
Fitted Sheet Seems Tight
The problem: The 14-inch deep pocket and strong elastic make the fitted sheet feel very snug, especially on a thick mattress.
My fix: This is actually by design to keep it in place on an adjustable bed. Start by fitting one corner, then the opposite corner, and work your way around. The elastic will stretch to fit.
Color Doesn’t Match Online Picture
The problem: The color you receive might look slightly different than it does on your screen.
My fix: This is common with any online purchase. I found the “Grey” to be a true, solid medium grey. Check the customer review photos on Amazon for more real-life examples before you buy.
Warranty & Support
The product listing has a link to click for warranty information, which is fairly standard. For any issues, your first stop should be the seller through Amazon’s return system, as they offer FREE Returns on some sizes. I always recommend checking the warranty details directly on the product page before purchase.

Frequently Asked Questions
What’s the difference between a Split King and a Split California King?
A standard split king is two Twin XL mattresses side-by-side, making a bed 76 inches wide by 80 inches long. A split California king is two shorter but wider mattresses, each 36″x84″, making a total bed 72 inches wide by 84 inches long. This Kingnex set is specifically for the latter size. Using a set for the wrong size will result in a very poor fit.
Are these sheets really soft?
Yes, they are very soft. The “double brushed microfiber” construction makes them feel gentle and smooth right out of the package. I didn’t experience any scratchiness. Just remember, softness is different from breathability—this 100% polyester fabric is soft but can feel warmer than cotton.
Will they fit my extra-thick mattress?
They should. The fitted sheets have a listed pocket depth of 14 inches, which is quite deep. It handled my mattress with a 3-inch topper without any issues. The elastic is strong, so you might need to stretch it a bit to get it over the last corner, but it’s designed to hold.
Do they wrinkle a lot?
Microfiber is generally low-wrinkle, and I found that to be true here. After washing and drying on low heat, I shook them out and put them on the bed. Any minor wrinkles from the dryer smoothed out quickly once on the mattress. They look neat with minimal effort.
What’s included in the 5-piece set?
You get two Cali Twin XL fitted sheets (36″x84″ each), one flat sheet (102″x108″), and two king-size pillowcases (20″x40″). It’s a complete solution for your split Cal King bed and means you don’t have to buy anything else separately.
How do I wash and care for them?
The care instructions are simple: machine wash in cold water with similar colors and tumble dry on low heat. I followed this exactly and had no problems with shrinkage or fading. Avoid high heat in the dryer, as it can damage the elastic and the microfiber over time.
My Final Verdict
After testing the Kingnex Striped Split California King Sheets, I can confidently say they solve a very specific problem brilliantly. The two 36″x84″ fitted sheets with 14-inch pockets fit my adjustable bed perfectly, and the double-brushed microfiber is undeniably soft. I wholeheartedly recommend this 5-piece set to any split Cal King owner who prioritizes a flawless fit. I would not recommend it for hot sleepers who need natural fiber breathability or for anyone with a standard split king bed.
The main limitation is the 100% polyester material, which isn’t as breathable as cotton. However, for the core task of fitting a split-top adjustable California King mattress, this compromise is worth it. The fit is so good that I’d buy them again for that reason alone.
