If you have a split king adjustable bed, you know finding sheets that actually fit both mattresses and stay put is a real challenge. I tried the XOOX Linen Split King Sheets Sets for Adjustable Bed to see if their 500 thread count cotton and 16″ deep pockets could solve that problem.
This set is specifically for people with adjustable bases who are tired of standard sheets popping off. The 100% Egyptian cotton feels soft and cool, but it’s a sateen weave, which some might find less crisp than percale. Let’s see how these sheets held up during my testing.

What Stands Out — Key Features
- True Split King Design: The set includes two separate Twin XL fitted sheets, which is essential for an adjustable bed. I found this stopped the sheets from pulling and bunching when I raised the head or foot.
- Deep Pocket & Secure Fit: The 16″ deep pockets with all-around elastic held my mattress snugly. Even with movement, the fitted sheets didn’t come loose overnight.
- 500 Thread Count Sateen Weave: Made from 100% Egyptian cotton, the fabric has a luxuriously smooth and silky feel. I noticed it had a nice luster and felt cool against my skin.
- Thoughtful Bed-Making Aids: The headside and footside indicator tags on the fitted sheets are a small detail that makes a big difference. No more guessing which way the sheet goes.
- OEKO-TEX Certified Fabric: Knowing the material is STANDARD 100 by OEKO-TEX validated gave me peace of mind about its safety and quality, especially for all-night use.
- Complete 5-Piece Set: You get everything you need: one king flat sheet (108″ x 106″), two king pillowcases, and the two Twin XL fitted sheets. It’s a full bedding refresh in one box.
- Durable Construction: The product details mention features like fade resistance, tear resistance, and resistance to pilling. In my use, the sheets have held their color and texture well after several washes.
- Easy Care Instructions: I just machine wash them in cold water and tumble dry on low. They came out of the dryer without major wrinkles and maintained their softness.

Pros & Cons — The Honest Take
✅ What I Like
- The split Twin XL fitted sheets are a perfect, functional fit for an adjustable king bed frame.
- The 16″ deep pockets with all-around elastic keep the sheets securely in place all night.
- The 500 thread count, 100% Egyptian cotton fabric is genuinely soft and has a cooling feel.
- Head and foot side tags on the fitted sheets make bed-making foolproof.
- OEKO-TEX certification means the materials meet a trusted safety and quality standard.
❌ What Could Be Better
- The sateen weave has a distinct silky-smooth feel that some might find too slick compared to crisp percale.
- At 8 pounds for the set, they are a bit heavier than some other cotton sheet sets I’ve tried.
For me, the pros massively outweigh the cons because they solve the core problem of fitting an adjustable bed. If you prefer a crisp, matte feel over a silky one, that’s the main trade-off to consider.
⚖️ How Does It Compare?
When looking at the XOOX Linen sheets, I found two other popular split king options that are worth considering. I chose these because they also specifically target adjustable beds and use high-quality cotton, but they have different weaves and thread counts.

🔵 Alternative 1: TEXAS LINEN CO.
Best for: People who want a crisp, cool percale feel instead of a silky sateen.
Key specs: 100% Cotton, Percale weave, 16″ deep pocket, check listing for thread count.
Where it beats the main product: The percale weave is more breathable and has a classic, matte hotel-sheet feel.
Where it falls short: It may not have the same high 500 thread count or the OEKO-TEX certification.

⚪ Alternative 2: THREAD SPREAD
Best for: Shoppers prioritizing a higher thread count for maximum softness.
Key specs: 100% Egyptian Cotton, 800 thread count, sateen weave, deep pocket.
Where it beats the main product: Its 800 thread count is significantly higher than the XOOX Linen’s 500, promising a denser, softer fabric.
Where it falls short: The higher thread count sateen can be warmer and is often priced higher.
If you dislike the slick feel of sateen, I’d recommend the TEXAS LINEN CO. percale sheets for their crisp breathability. If your main goal is the highest possible thread count for softness and you don’t mind a warmer feel, the THREAD SPREAD 800-count is the clear choice. For a balanced option with good 500 thread count softness, OEKO-TEX certification, and a competitive price, the XOOX Linen set is my pick.
How It Actually Performs
Fit & Security on the Mattress
The 16″ deep pocket and all-around elastic are the real stars here. On my 14″ mattress, the fitted sheets went on easily and stayed perfectly taut. Even with my adjustable base moving, the sheets didn’t budge or pull off the corners. The head/foot side tags made putting them on correctly the first time a breeze. This solved my biggest adjustable bed problem completely.
Comfort & Feel
The 500 thread count Egyptian cotton in a sateen weave delivers on its promise of a smooth, silky feel. I found them soft and cool to the touch, especially in the first few minutes of getting into bed. They have a noticeable sheen and a heavier, drapier feel than percale. If you love that luxurious hotel sheet vibe, you’ll like this. If you prefer a crisp, matte texture, this might not be for you.
Durability & Care
After several washes following the care instructions (cold water, tumble dry low), the sheets have held up well. The color in Sea Foam hasn’t faded, which matches the “fade resistant” claim. I haven’t seen any pilling yet on the surface. At 8 pounds for the set, they feel substantial. The single pleat hem on the flat sheet and pillowcases still looks neat, adding to the durable, quality impression.
Temperature Regulation
The product lists “cooling” as a feature, and I’d say they are breathable for a sateen weave. They didn’t make me feel overly warm, but they aren’t as airy as a true percale. The 100% cotton fabric does a good job of wicking moisture. For year-round use in a climate-controlled room, they work well. If you’re an extremely hot sleeper, you might find a percale weave more effectively cooling.
Who Should Buy This Generator?
Not every sheet set is right for every person. Based on my testing, here’s who will get the most out of these sheets and who might be better off with a different option.
✅ This Is a Great Fit If You…
- Own a split king adjustable bed and are tired of standard sheets popping off the corners.
- Prefer the soft, silky feel of a sateen weave over a crisp percale.
- Want the peace of mind that comes with OEKO-TEX certified, 100% Egyptian cotton fabric.
- Appreciate small conveniences like head/foot indicators and deep pockets that actually fit up to 16″ mattresses.
❌ You Might Want to Look Elsewhere If…
- You strongly dislike the slick, heavy drape of sateen and prefer a crisp, matte percale feel.
- You are an extremely hot sleeper and need the most breathable, cooling fabric possible.
- You need a pocket deeper than 16 inches for an extra-thick mattress.
My top recommendation is for adjustable bed owners who value a secure fit and a soft, luxurious feel. The XOOX Linen Split King Sheets solve the core fitting problem brilliantly, making them a smart upgrade for that specific setup.

Common Issues & Fixes
Even great products can have little quirks. Here are a few things I ran into or can foresee, and how to handle them.
Sheets Feel Too Slick or Silky
The problem: The sateen weave has a distinct smooth feel that some people find too slippery.
My fix: Wash them a couple of times before use; this can soften the initial finish. If you still don’t like the feel, a percale weave sheet set might be a better match for you.
Fitted Sheet Seems Tight or Loose
The problem: The fit might feel off if your mattress depth is at the extreme end of the 8-16 inch range.
My fix: Double-check your mattress depth. For a very thin mattress, the extra fabric might tuck in loosely. For a mattress right at 16″, it will be a very snug, secure fit.
Wrinkles After Washing
The problem: The sheets come out of the dryer with more wrinkles than you’d like.
My fix: Follow the care label: tumble dry on low or medium heat and remove them promptly. I found a medium heat cycle and taking them out while slightly damp helped minimize wrinkles before folding.
Flat Sheet Seems Too Large
The problem: The king flat sheet measures 108″ x 106″, which can feel overly large on some bed setups.
My fix: This is by design for adjustable beds that elevate, needing extra length. For a standard flat bed, you can neatly tuck the excess under the mattress or consider a more tailored flat sheet.
Warranty & Support
The product listing has a link to click for specific warranty information, which I recommend checking on Amazon. For any issues, your first step should be to contact the seller through Amazon’s platform, as they typically handle returns and support directly.

Frequently Asked Questions
What exactly is in the 5-piece set?
The set includes one king-size flat sheet (108″ x 106″), two Twin XL fitted sheets for the split mattresses, and two king-size pillowcases (21″ x 41″). This is the standard and necessary configuration for a split king adjustable bed, so you don’t need to buy anything extra.
How deep are the pockets on the fitted sheets?
The pockets are designed to fit mattresses from 8 to 16 inches deep. My 14-inch mattress fit perfectly with plenty of elastic to spare underneath. The all-around elastic really helps keep it secure, especially when the bed is adjusted.
Are these sheets really cooling?
They are breathable for a sateen weave because they’re 100% cotton. I found them cool to the touch initially and comfortable for most of the year. However, if you’re an extremely hot sleeper, you might find a percale weave more effectively cooling than this silky sateen.
What does OEKO-TEX certification mean?
It means the fabric has been tested by an independent organization for harmful substances. The STANDARD 100 by OEKO-TEX label gives me confidence that the materials meet strict safety standards, which is important for something you sleep on every night.
How do they hold up after washing?
I’ve washed them several times in cold water and dried on low heat as instructed. The color in Sea Foam has not faded, and I haven’t seen any pilling. They maintain their softness and weight, making them a durable choice for daily use on an adjustable bed.
Will these work on a regular king bed?
No, they won’t. A regular king bed uses one large fitted sheet. This set has two separate Twin XL fitted sheets designed specifically for the two mattresses of a split king adjustable base. Using them on a standard king would be very awkward.
My Final Verdict
After testing the XOOX Linen Split King Sheets, I can confidently say they solve the main problem for adjustable bed owners. The two Twin XL fitted sheets with 16″ deep pockets stay perfectly in place, and the 500 thread count Egyptian cotton is soft and cooling. I recommend them to anyone with a split king base who loves a silky sateen feel. I would not recommend them to hot sleepers who prefer crisp percale or to people with a standard king bed.
The sateen weave is the main trade-off—it feels luxurious but can be too slick for some. For me, the perfect fit and secure hold on my adjustable mattress outweigh that personal preference. If your priority is a sheet set that actually works with your bed’s movement, these are a solid choice.
Ready to Check the Price?
If you own a split king adjustable bed and want sheets that fit securely and feel soft, this set is definitely worth checking out.
