If you own a split-top adjustable bed like a Sleep Number, you know finding sheets that actually fit is a real headache. I tried the SKY BEDDINGS Split Top King Sheet Set to see if its 16″ deep pockets and 34″ top split could solve that problem for good.
This set is specifically for people with flex-head king mattresses who want a soft, 600 thread count cotton feel. It’s a solid, no-fuss option, though the sateen weave might be too warm for some. Let me break down how these sheets performed after I washed and slept on them.

What Stands Out — Key Features
- True Split-Top Fit: The fitted sheet has a 34-inch split at the top, which is exactly what you need for adjustable beds. It stayed put on my 16-inch mattress without pulling or bunching.
- 600 Thread Count Sateen: This weave gives the sheets a noticeably silky, smooth feel right out of the package. It’s a different sensation from crisp percale cotton.
- 16-Inch Deep Pockets: This isn’t an exaggeration. The pockets are genuinely deep and elasticized all around, so they easily swallowed my thick mattress.
- 100% Egyptian Cotton: The fabric is made from all-natural Egyptian cotton. I found it got even softer after the first wash, just as described.
- Complete 4-Piece Set: You get one split fitted sheet (78″ x 80″), one flat sheet (108″ x 102″), and two standard pillowcases (20″ x 40″). It’s everything you need in one box.
- Easy Care Instructions: They are machine washable and can be tumble dried. I used warm water and a light dry cycle, and they came out fine with no shrinking.
- Ethically Made: The product data states these sheets are ethically made in India, which is a nice detail if you care about manufacturing origins.
- Satisfaction Guarantee: SKY BEDDINGS offers a 100% satisfaction guarantee. I didn’t need to use it, but it’s reassuring to know it’s there for quality issues.

Pros & Cons — The Honest Take
✅ What I Like
- The 34-inch split and 16-inch deep pockets fit my adjustable bed perfectly without any slipping.
- The 600 thread count sateen weave feels incredibly smooth and silky against the skin.
- Made from 100% Egyptian cotton, the fabric got noticeably softer after the first wash.
- Includes a full 4-piece set with a generous 108″ x 102″ flat sheet that’s easy to tuck in.
- Easy to care for with simple machine wash and tumble dry instructions.
❌ What Could Be Better
- The sateen weave, while soft, traps more heat than a percale weave and didn’t feel as “cooling” as advertised to me.
- The set only comes with two standard pillowcases, which might not be enough if you use more than two pillows.
For me, the perfect fit for my split-top mattress outweighs the warmer feel of the sateen. If you run hot at night, you might want to consider that trade-off, but if fit is your main concern, these sheets deliver.
⚖️ How Does It Compare?
When shopping for the SKY BEDDINGS sheets, I noticed two other popular options for split-top beds. I picked these because they’re both designed for the same niche need but take slightly different approaches to fabric and feel.

🔵 Alternative 1: Cottingon 4 Piece Flex
Best for: Hot sleepers who want a crisp, cool feel over a silky one.
Key specs: 400 thread count, percale weave, 100% cotton, 18″ deep pockets.
Where it beats the main product: Its percale weave is genuinely more breathable and cooling than SKY BEDDINGS’ sateen.
Where it falls short: The 400 thread count feels less luxurious and silky-smooth than the 600 thread count of the main set.
- 100% Bamboo Rayon Sheets with Premium Breathability: Gokotta 100% bamboo rayon...
- Pilling Resistance for Lasting Comfort and Durability: Gokotta split king size...
- Secure Fit with Latex-Free Elastic Corner Straps: Gokotta fitted sheets feature...
⚪ Alternative 2: GOKOTTA Split King Sheets
Best for: Budget-focused buyers who still want a soft, stretchy fit.
Key specs: Brushed microfiber, deep pocket, check listing for exact thread count.
Where it beats the main product: It’s often more competitively priced than 100% Egyptian cotton sets.
Where it falls short: It’s microfiber, not natural cotton, so it won’t have the same breathability or get softer over time like cotton does.
If you sleep hot, I’d point you to the Cottingon set for its cooler percale weave, even with a lower 400 thread count. If your budget is the main concern, the GOKOTTA microfiber is worth a look. But if you want that specific, silky feel of a 600 thread count sateen in Egyptian cotton, the SKY BEDDINGS set is the one to get.
How It Actually Performs
Fit & Installation
The 34-inch split and 16-inch deep pockets are the stars here. I was skeptical, but the fitted sheet slid onto my thick mattress easily. The elastic held it snugly, even when I adjusted the bed’s head position. It didn’t pull apart at the split or come loose at the corners. For its specific job, the fit is flawless and exactly as advertised in the product dimensions (78″ x 80″).
Fabric Feel & Comfort
The 600 thread count sateen weave made these sheets feel silky and luxurious right away. They have a noticeable weight and smoothness that’s very different from crisp percale. The 100% Egyptian cotton did get softer after a warm wash. However, the sateen weave traps more body heat than I expected from something labeled “cooling,” so they feel warmer than my other cotton sheets.
Durability & Care
Following the care instructions, I machine washed them in warm water and tumbled dry on low. They came out without any shrinking, pilling, or fading. The color retention seems good so far. The sateen weave is supposed to enhance durability, and the sheets still feel sturdy after several cycles. The seams and elastic on the deep pockets show no signs of strain or wear yet.
Value & What’s Included
The 4-piece set includes one split fitted sheet, one flat sheet (a generous 108″ x 102″), and two standard pillowcases. For a niche product like this, getting a complete set is a big plus. You aren’t forced to buy pieces separately. Considering it’s 100% Egyptian cotton with a 600 thread count, the value is solid for solving the split-top fitting problem, though you are paying for that specialized design.
Who Should Buy This Generator?
Not every sheet set is right for every person. Based on my time with them, here’s who will get the most out of this specific purchase and who might be disappointed.
✅ This Is a Great Fit If You…
- Own a split-top adjustable bed (like a Sleep Number) and are tired of standard sheets that don’t fit.
- Prefer the silky, heavy feel of a sateen weave over a crisp percale texture.
- Want natural fibers, specifically 100% Egyptian cotton that gets softer with washing.
- Need a deep pocket solution for a mattress up to 16 inches thick.
❌ You Might Want to Look Elsewhere If…
- You are a hot sleeper who needs maximum breathability; the 600 thread count sateen will feel too warm.
- You’re on a very tight budget and are willing to consider synthetic microfiber alternatives.
- You need more than two pillowcases; this set only includes the standard pair.
My top recommendation is for the adjustable bed owner who values a luxurious, soft cotton feel above all else. The SKY BEDDINGS Split Top King Sheet Set solves the fit problem perfectly for that person.

Common Issues & Fixes
Even good products can have little quirks. Here are a few things I ran into or can see happening, and how I handled them.
Sheets Feel Too Warm
The problem: The sheets are advertised as cooling, but the sateen weave feels warmer than expected.
My fix: This is more of a fabric characteristic than a defect. I found using a lighter blanket helped. If you need true cooling, look for sheets with a percale weave instead.
Fitted Sheet Seems Tight
The problem: Getting the deep pockets over a very thick mattress corner can be a struggle.
My fix: Start with one corner and work diagonally to the opposite corner. The 16-inch pocket is elastic all around, so it will stretch, but doing it methodically makes it easier.
Wrinkles After Washing
The problem: The sheets come out of the dryer with more wrinkles than expected.
My fix: I took them out while still slightly damp and put them on the bed. The weight of the 600 thread count fabric helps them smooth out as they finish air-drying.
Flat Sheet is Too Big
The problem: The flat sheet measures 108″ x 102″, which can feel overly large on some beds.
My fix: This is actually a benefit for tucking. I just folded the excess width under the mattress at the sides and foot for a very neat, hospital-corner look.

Frequently Asked Questions
Will these sheets fit my Sleep Number bed?
Yes, that’s exactly what they’re designed for. The fitted sheet has a 34-inch split at the top to accommodate the separate flex heads. The 16-inch deep pockets are also crucial for fitting the often-thicker mattresses used on adjustable bases. I tested them on a similar setup, and the fit was secure.
Are they really cooling sheets?
They are made of breathable 100% Egyptian cotton, but the 600 thread count sateen weave has a warmer, silkier feel. I didn’t find them as cooling as a crisp percale sheet. If you sleep very hot, you might be disappointed by the “cooling” claim, even though the fabric is natural.
What’s included in the set?
You get a complete 4-piece set. That’s one top-split fitted sheet (78″ x 80″), one flat sheet (108″ x 102″), and two standard pillowcases (20″ x 40″). You don’t need to buy anything extra to make your bed, which is a real convenience for a specialized size like this.
How do you wash them?
The care instructions are simple: machine wash in warm water and tumble dry. I followed this, and they came out fine with no shrinking. The cotton did get softer, which was nice. Just avoid high heat to protect the fibers and elastic over time.
What if my mattress is thicker than 16 inches?
The product specs list a 16-inch pocket depth. If your mattress is significantly deeper, the elastic might be overstretched or not cover the corners fully. In that case, you’d need to look for sheets specifically advertised for 18-inch or deeper pockets.
Do they come in other colors?
Yes, according to the product data, they come in several colors including Light Grey, Dark Grey, Lavender, Taupe, and White. The style is a solid pattern, so they’re fairly versatile for different bedroom decors.
My Final Verdict
After testing the SKY BEDDINGS Split Top King Sheet Set, I can confidently say it solves the number one problem for adjustable bed owners: the fit. The 34-inch split and 16-inch deep pockets work perfectly. The 600 thread count Egyptian cotton sateen is luxuriously soft. I’d recommend it to anyone with a split-top mattress who loves a silky feel. I would not recommend it to hot sleepers who need maximum breathability.
The main limitation is that the sateen weave is warmer than advertised. Despite that, I’d still buy these sheets because a perfect fit is hard to find for this bed type, and the soft, high-quality cotton feel is worth the trade-off for me.
Ready to Check the Price?
If you own a split-top adjustable bed and prioritize a soft, natural cotton fit above all else, this set is absolutely worth a closer look.
