If you have an adjustable split king bed, you know the struggle of finding sheets that actually fit. I was tired of standard king sheets bunching up when I raised the head or foot. I tested the Mattress-Homes Split King Sheets for Adjustable Bed 5 Piece to see if their two separate 39″ x 80″ fitted sheets solved the problem.
This set is specifically for split king adjustable beds, not a standard king. The 100% long staple combed cotton feels soft and breathable, which is great for year-round use. However, the sateen weave might feel a bit slippery to some. Let me break down how they performed after several washes.

What Stands Out — Key Features
- True Split King Design: The set includes two separate fitted sheets, each measuring 39″ x 80″. This is the key feature for adjustable beds, as each side can move independently without pulling the sheet off the other side.
- Deep Pocket Fit: The fully elasticized fitted sheets are designed to snugly fit mattresses from 8 to 16 inches deep. I found they had enough stretch to handle my thicker mattress without popping off.
- Soft Cotton Material: They’re made from 100% long staple combed compact cotton with a 600 thread count. I found them breathable and cozy, living up to the “year-round comfort” claim.
- Complete 5-Piece Set: You get two fitted sheets, one flat sheet (102″ x 108″), and two standard pillowcases (20″ x 40″). It’s a full set ready to go out of the bag.
- Easy Care Instructions: The care is straightforward: machine wash in cold water and tumble dry on low. I followed this and didn’t experience any major shrinkage.
- Variety of Colors: The sheets come in multiple solid colors like White, Dark Grey, and Navy Blue. This makes it easier to match your existing bedroom decor.
- Sateen Weave: The product data lists a sateen weave type. This gives the sheets a smooth, slightly lustrous feel, but it also means they can feel slippery compared to a percale weave.

Pros & Cons — The Honest Take
✅ What I Like
- The two separate fitted sheets actually work for an adjustable split king bed, which is a huge win.
- The 100% long staple combed cotton is soft and breathable, making it comfortable year-round.
- Deep pockets with full elastic fit my thick mattress up to the advertised 16 inches without slipping.
- It’s a complete 5-piece set, so you get everything you need right away.
- Easy care—just machine wash in cold water and tumble dry low, with no fussy instructions.
❌ What Could Be Better
- The sateen weave feels a bit slippery, which might bother people who prefer a crisp percale feel.
- The flat sheet is one large piece (102″ x 108″), which can be tricky to manage on a split bed when it’s adjusted.
For me, the pros heavily outweigh the cons because they solve the core problem of fitting an adjustable split king. If you prioritize function and softness over a crisp, non-slip feel, these are a great pick.
⚖️ How Does It Compare?
When shopping for split king sheets, you’ll see a few main options. I’m comparing the Mattress-Homes set to two other popular styles: a budget-friendly flex version and a higher-thread-count luxury set.

🔵 Alternative 1: Cottingon 4 Piece Flex
Best for: Budget-conscious buyers who want a simple, flexible sheet solution.
Key specs: 4-piece set, check listing for material, often a flex-fit design.
Where it beats the main product: It’s often more affordable and uses a single fitted sheet with a split corner design.
Where it falls short: The single fitted sheet can still pull and bunch more than two separate sheets on a highly adjustable bed.

⚪ Alternative 2: LANE LINEN 1000TC
Best for: Those who prioritize a high thread count and a denser, more luxurious feel.
Key specs: 1000 thread count, 100% cotton, sateen weave, deep pocket.
Where it beats the main product: The 1000 thread count offers a noticeably heavier, more substantial and silky feel than the 600 thread count.
Where it falls short: It may not be specifically designed as a split king set with two separate fitted sheets, which is the core feature of the Mattress-Homes.
If you’re on a tight budget and don’t adjust your bed constantly, the Cottingon flex set could save you money. If you want the absolute softest, densest feel and a standard king is fine, the LANE LINEN 1000TC is worth a look. But for a dedicated split king adjustable bed, the Mattress-Homes set with its two separate 39″ x 80″ fitted sheets is still the most functional choice.
How It Actually Performs
Fit on an Adjustable Bed
This is the main event, and the sheets deliver. The two separate 39″ x 80″ fitted sheets are the key. When I raised the head of my bed, only that side’s sheet moved, leaving the other side perfectly smooth. The deep pocket with full elastic handled my 14-inch mattress easily, staying snug without popping off. It completely solved the bunching problem I had with a standard king sheet.
Comfort and Feel
The 100% long staple combed cotton with a 600 thread count is soft and breathable right out of the package. I found them lightweight and comfortable for year-round use, as advertised. The sateen weave gives them a smooth, slightly cool feel. However, that same sateen finish makes them feel a bit slippery, which is a trade-off for the softness. They don’t have a crisp, percale texture.
Durability and Care
I’ve washed these several times following the care instructions: cold water wash and tumble dry low. I haven’t noticed any significant shrinkage or fading in the white color. The elastic still feels strong. The cotton has held up well to regular use, maintaining its softness. For the price point, they seem well-made and practical for everyday laundering.
Overall Usability
The 5-piece set is convenient. Having two pillowcases and the large 102″ x 108″ flat sheet means you’re fully set up. The one limitation is that large flat sheet; it can get tangled when the bed is in a raised position. For pure, hassle-free function on the adjustable base, the fitted sheets are perfect. For overall bed-making ease with the flat sheet, it takes a bit more tucking.
Who Should Buy This Generator?
Not every sheet set is right for every bed. Based on my testing, 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 true split king adjustable bed and are tired of standard sheets bunching up.
- Want the convenience of a complete 5-piece set with two separate fitted sheets ready to go.
- Prefer the soft, breathable feel of 100% cotton with a 600 thread count for year-round use.
- Have a mattress up to 16 inches thick and need deep pockets that will stay put.
❌ You Might Want to Look Elsewhere If…
- You have a standard king bed; a regular king sheet set will be simpler and likely cheaper.
- You dislike the smooth, slightly slippery feel of a sateen weave and prefer crisp percale.
- You’re on a very tight budget and a flex-fit single sheet design would suffice for minimal adjustments.
My top recommendation is for the person with a frequently used adjustable split king. The Mattress-Homes Split King Sheets solve that core problem perfectly, making the minor trade-offs worth it.

Common Issues & Fixes
Even a good product can have small quirks. Here are a few things I ran into or heard about, and how to handle them.
Sheets Feel Slippery
The problem: The sateen weave makes the sheets feel slick, and they might slide around more than you’re used to.
My fix: This is just the nature of the material. Make sure the deep pocket elastic is fully tucked under all corners of your mattress. A mattress pad or topper underneath can also help create more grip.
Flat Sheet is Too Big or Tangled
The problem: The single 102″ x 108″ flat sheet is large and can get caught when adjusting the bed.
My fix: I use hospital corners and tuck it in tightly on all sides when the bed is flat. If you rarely use a flat sheet, you can simply skip it and just use the fitted sheets and a duvet.
Initial Shrinkage After Wash
The problem: The sheets feel a bit tighter after the first wash.
My fix: Always wash in cold water and tumble dry on low, as instructed. I didn’t experience major shrinkage, but this helps minimize it. Putting them on the mattress slightly damp can also let them stretch to fit.
Color Transfer in Wash
The problem: Darker colors in the set might bleed dye in the first few washes.
My fix: Wash dark colors separately for the first few cycles, as the care instructions suggest. Using a color-catching sheet in the wash is also a good preventative step.
Warranty & Support
The product listing has a link to click for warranty information, which you should check on Amazon for the most current details. For any issues, I’d start with the seller through Amazon’s return system, which offers FREE Returns on some sizes.

Frequently Asked Questions
Are these sheets really for a split king bed?
Yes, they are specifically designed for a split king adjustable bed. The key is the two separate fitted sheets, each measuring 39 inches by 80 inches. This lets each side of your adjustable base move independently. A standard king sheet is one piece that’s 76 inches by 80 inches, which will bunch up.
What is the thread count and material?
The thread count is 600, and the material is 100% long staple combed compact cotton. It has a sateen weave, which makes it feel soft and smooth but also a bit slippery. I found them breathable and comfortable, but they don’t have the crisp feel of a percale weave.
How deep are the pockets on the fitted sheets?
The pockets are designed to fit mattresses from 8 inches to 16 inches deep. The elastic goes all the way around the sheet. On my 14-inch mattress, they fit snugly without coming loose, even when I adjusted the bed.
Can I buy just one side of the split king set?
No, this set is sold as a complete 5-piece unit. You get two fitted sheets, one flat sheet, and two pillowcases. If you only need one side, you’d have to buy a separate Twin XL sheet set, but it wouldn’t match this set exactly.
Do they shrink a lot after washing?
I didn’t experience major shrinkage. You must follow the care instructions: machine wash in cold water and tumble dry on low. Washing in hot water or high heat drying will likely cause them to shrink. I found them to be a reliable and practical choice after several washes.
What’s included in the 5-piece set?
You get two Twin XL fitted sheets (39″ x 80″ each), one flat sheet (102″ x 108″), and two standard pillowcases (20″ x 40″). It’s everything you need to make the bed. Just note that the flat sheet is one large piece for the entire bed width.
My Final Verdict
After testing them, I can confidently say the Mattress-Homes Split King Sheets solve the main problem for adjustable bed owners. The two separate 39″ x 80″ fitted sheets work exactly as intended, and the 600 thread count cotton is soft and breathable. I’d absolutely recommend these to anyone with a split king adjustable base. I would not recommend them for a standard king bed or for someone who dislikes the feel of sateen weave.
The sateen weave is slick, and the large flat sheet can be cumbersome. But for me, the core function—sheets that stay put on an adjustable bed—outweighs those quirks. If your priority is hassle-free performance on a split king, this set delivers.
