This set is my top pick because it delivers on its promises. The 800 thread count sateen weave feels thick and buttery smooth right away, and it has the Good Housekeeping Seal to back up its quality. It’s perfect for anyone who wants a proven, hotel-style sheet that gets softer with each wash. My only note is that the 15-inch pocket depth might be snug if you have a mattress thicker than that.
✅ Pros
- Highest verified rating (4.5 from 5,809 reviews)
- OEKO-TEX certified and Good Housekeeping Seal
- True 800 thread count with a substantial, soft feel
- Includes head/foot tags for easy bed-making
❌ Cons
- 15″ pocket depth is slightly shallower than competitors
- Only includes 2 pillowcases in the 5-piece set

- LUXURIOUS QUALITY BEDDING SHEETS: We have crafted these sheets Super Soft...
This SKY BEDDINGS set is a smart choice if you have a split-top adjustable bed, like a Sleep Number. The 600 thread count Egyptian cotton is breathable and the 16-inch deep pocket fits thicker mattresses well. I think it’s best for someone who prioritizes a specific split-top fit and a competitively priced option. The main trade-off is that it’s a 4-piece set, so you only get two pillowcases.
✅ Pros
- Designed specifically for split-top adjustable beds
- Full 16-inch deep pocket for thick mattresses
- Made from breathable 100% Egyptian cotton
- Competitively priced
❌ Cons
- Lower 600 thread count than the others
- Only a 4-piece set (fewer components)
- Smaller pool of customer reviews (112)
ECONEST LIVING 100% Egyptian Cotton Split King Sheet Set

- SHEET SET WITH A GREAT FIT: Our 7-piece high thread count cotton sheet set...
- BREATHABLE AND COOLING FABRIC:Made from 100% natural Egyptian cotton, this sheet...
If you want the highest thread count on paper, this 1000TC set from ECONEST LIVING is your pick. The 7-piece bundle is a great value, including four pillowcases, and the 100% Egyptian cotton should be breathable. It’s ideal for the buyer who wants maximum luxury specs and extra pillowcases. Just know that with a 4.2-star rating from 89 reviews, it doesn’t have the same long-term user feedback as the top pick.
✅ Pros
- Highest thread count at 1000
- Most complete 7-piece set with 4 pillowcases
- 16-inch deep pocket fits most mattresses
- Made from premium 100% Egyptian cotton
❌ Cons
- Lower customer rating (4.2) with fewer reviews (89)
- Very high thread count can sometimes feel less breathable
Which One Should You Buy?
There’s no single “best” sheet set here. The right pick depends entirely on what you value most for your adjustable bed. I’ll match each set to a specific type of buyer.
California Design Den Split King Sheets Sets for Adjustable Bed is right for you if…
- You want the most trusted option with over 5,800 verified 4.5-star reviews.
- You prioritize a buttery-soft 800 thread count sateen feel from day one.
- Certifications like the Good Housekeeping Seal are important to you.
SKY BEDDINGS Split Top King Sheet Set is right for you if…
- You have a split-top adjustable bed (like a Sleep Number) and need that specific 34″ split fit.
- You need a full 16-inch deep pocket for a very thick mattress.
- You want a competitively priced set made from breathable 600TC Egyptian cotton.
ECONEST LIVING 100% Egyptian Cotton Split King Sheet Set is right for you if…
- The highest possible thread count (1000) is your main buying criteria.
- You want the most complete bundle with four pillowcases in a 7-piece set.
- You prefer the reputation of 100% Egyptian cotton above all else.
❌ Who Should Skip All of These?
If you don’t have a split king adjustable bed, these sets are the wrong fit. Also, if you strongly prefer a crisp percale weave over a silky sateen, you should look for a percale-specific set instead.
For most people with a standard split king adjustable bed, my top recommendation is the California Design Den set. Its combination of proven quality, great feel, and strong user feedback makes it the safest and most satisfying choice.
Frequently Asked Questions
Is a 1000 thread count sheet better than an 800 thread count?
Not necessarily. While ECONEST LIVING’s 1000 thread count is higher on paper, thread count isn’t the only measure of quality. California Design Den’s 800 thread count sateen has a much higher customer rating (4.5 vs 4.2) from thousands more users. The weave, cotton quality, and construction matter just as much. I’d choose the proven 800TC set over the higher, but less-proven, 1000TC.
Which split king sheets fit a Sleep Number bed best?
The SKY BEDDINGS set is specifically designed for split-top adjustable beds like Sleep Number. It has a 34-inch split on the top fitted sheet, which matches the flex head design. The California Design Den and ECONEST LIVING sets are for standard split king beds where only the bottom is split. If you have a split-top model, SKY BEDDINGS is your clear choice.
Are Egyptian cotton sheets worth the extra money?
Both SKY BEDDINGS (600TC) and ECONEST LIVING (1000TC) use Egyptian cotton, which is known for long, soft fibers. However, the California Design Den set uses long-staple cotton and has the best reviews. You’re paying for verified quality and feel, not just a label. For most people, the California Design Den offers better value, even without the “Egyptian” name.
Which set comes with the most pillowcases?
The ECONEST LIVING set wins here. It’s a 7-piece bundle that includes four king-size pillowcases. Both the California Design Den and SKY BEDDINGS sets only include two pillowcases in their 5-piece and 4-piece sets, respectively. If you use more than two pillows, the ECONEST set gives you more for your money upfront.
What’s the deepest pocket available?
Both the SKY BEDDINGS and ECONEST LIVING sets have a 16-inch deep pocket. The California Design Den set has a slightly shallower 15-inch pocket. If your mattress is very thick, over 15 inches, you should choose either the SKY BEDDINGS or ECONEST LIVING set to ensure a proper fit.
Which brand has the best customer satisfaction?
California Design Den has the strongest record of customer satisfaction by a wide margin. It has a 4.5-star rating from 5,809 reviews. SKY BEDDINGS has 4.3 stars from 112 reviews, and ECONEST LIVING has 4.2 stars from 89 reviews. For peace of mind and proven performance, California Design Den is the most reliable choice.
My Final Verdict
After comparing every detail, the California Design Den 800TC is my clear winner. Its 4.5-star rating from over 5,800 buyers proves its buttery-soft 800 thread count sateen delivers reliable quality and comfort. The runner-up, SKY BEDDINGS, is the only correct choice if you specifically need sheets for a split-top adjustable bed with its 34-inch split design.
If you’re stuck deciding, go with the proven crowd favorite. The California Design Den set has the trust of thousands of users and certifications like the Good Housekeeping Seal, which is more valuable than a slightly higher thread count on paper.
