If you own a split head adjustable king bed, you know finding the right fitted sheet is a real challenge. I’m looking at two popular options: the Coldwind Split Top King Sheets Only and the Horbaunal Split Top King Fitted Sheet Only. The key specs to watch are their pocket depths and how they handle that 34-inch split from the head.
This comparison is for anyone with a flex head adjustable bed who needs a sheet that won’t bunch up. The main trade-off is between a deeper pocket and a handy extra feature. Let me break down which sheet will give you a better night’s sleep.

Individual Product Breakdown
I looked closely at how each sheet fits, feels, and holds up based on the specs and what real users are saying. Here’s my honest take on each one.
Coldwind Split Top King Sheets Only
18″ Deep Pocket | 34″ Top Split | 120 Thread Count | 4.2 Stars (422)
- Split Top King Size 1Pcs Fitted Sheet-: 1 Split Top Fitted Sheet 78" wide X...
- Perfect Snug Fit: Measuring 78" x 80" with 18 inch deep pocket, this Split top...
- Stretchable: The Split Head Flex King Fitted Sheet only deep pocket have...
This is my top pick because it’s built for thicker mattresses with its 18-inch deep pocket, and it has a much stronger track record with over 400 reviews. I found the 120-thread count microfiber to be soft and stretchy, which is key for staying snug on an adjustable bed. It’s perfect for anyone with a mattress topper or a mattress over 16 inches thick. The main limitation is that it doesn’t have any extra features like a storage pocket.
✅ Pros
- Deeper 18″ pocket fits thicker mattresses
- Higher 4.2-star rating from 422 users
- Stretchy elastic all around for a secure fit
- Competitively priced
❌ Cons
- Lower thread count than the competitor
- No extra features like a storage pocket
Horbaunal Split Top King Fitted Sheet Only for Adjustable Beds

The Horbaunal sheet stands out with its very high 1800 thread count and the clever addition of a side storage pocket. I think that pocket is a great touch for keeping a remote or glasses handy. It’s a solid choice for someone with a standard-depth adjustable mattress who values that extra bit of convenience. However, the 16-inch pocket depth is a limitation if your mattress is on the thicker side, and the user feedback is based on a much smaller pool of reviews.
✅ Pros
- Very high 1800 thread count for a smooth feel
- Built-in side storage pocket is super handy
- Fade-resistant fabric per manufacturer claims
❌ Cons
- Shallower 16″ pocket won’t fit very thick mattresses
- Lower overall rating with fewer reviews
Which One Should You Buy?
Choosing between these two sheets really comes down to your specific mattress and what you value most. I think the best choice is clear once you match your needs to their strengths.
Coldwind Split Top King Sheets Only is right for you if…
- Your mattress or mattress topper is thicker than 16 inches.
- You prioritize proven reliability and want a sheet with hundreds of positive reviews.
- You want the deepest possible pocket (18″) to ensure a secure, non-slip fit.
Horbaunal Split Top King Fitted Sheet Only for Adjustable Beds is right for you if…
- You love the idea of a built-in side pocket for your remote, phone, or glasses.
- Your mattress is 16 inches thick or less and you prefer a very high thread count feel.
- You’re willing to try a newer product with a smaller number of reviews for its unique feature.
❌ Who Should Skip All of These?
If you have a regular, non-adjustable king-size bed, you should skip these entirely. They are specifically designed for a 34-inch split at the head of an adjustable bed frame and won’t fit a standard king mattress properly.
For most people with an adjustable bed, I recommend the Coldwind. Its deeper pocket and stronger user satisfaction record make it the safer, more reliable choice for a good night’s sleep.
Frequently Asked Questions
Which split top king sheet is better for a thick mattress?
The Coldwind is definitely better for a thick mattress. Its pocket is 18 inches deep, while the Horbaunal’s is only 16 inches. If your mattress or mattress topper is over 16 inches thick, the Coldwind is the only one that will fit properly without pulling off the corners.
Is the Horbaunal’s higher thread count worth it?
In my opinion, no, not in this case. While the Horbaunal has a 1800 thread count versus the Coldwind’s 120, thread count isn’t the only measure of quality. The Coldwind has a much higher user rating (4.2 vs 3.7 stars) from far more people, which tells me its microfiber fabric performs better in real use on an adjustable bed.
Do both sheets fit the same adjustable bed?
Yes, both are designed for the same standard split head king size. They both measure 78 inches wide by 80 inches long with a 34-inch split from the top. The key difference is how deep they can go, not how wide or where the split is located.
Which sheet stays on better during the night?
Based on the specs and reviews, the Coldwind likely stays on better. It has a deeper 18-inch pocket with elastic all around, which gives it more material to grip a mattress. The Horbaunal’s shallower 16-inch pocket might struggle to stay secure on thicker setups, which is a common complaint for ill-fitting sheets.
Is the Horbaunal’s storage pocket a useful feature?
Yes, the storage pocket is genuinely useful if you keep small items like a remote or reading glasses by the bed. It’s the Horbaunal’s main advantage. If that specific convenience is a top priority for you and your mattress is 16 inches or thinner, it could be the deciding factor.
Which one offers better value for the money?
I believe the Coldwind offers better value. It’s competitively priced and solves the core problem—staying on a thick, adjustable mattress—more effectively with its 18-inch pocket. The Horbaunal’s main extra, the storage pocket, doesn’t add value if the sheet itself doesn’t fit your mattress properly.
My Final Verdict
After comparing them side-by-side, I declare the Coldwind Split Top King Sheets Only the clear winner. Its 18-inch deep pocket is the key advantage, ensuring a secure fit on thicker adjustable mattresses that the 16-inch Horbaunal can’t handle. Combined with a significantly higher 4.2-star rating from over 400 users, it’s the more reliable choice. The Horbaunal is best for someone with a standard-depth mattress who absolutely must have that side storage pocket.
If you’re on the fence, measure your mattress depth. If it’s over 16 inches, the decision is made for you—go with the Coldwind. If it’s exactly 16 inches or less, then you can weigh the Coldwind’s proven fit against the Horbaunal’s convenient pocket.
