If you own a split-top adjustable bed like a Sleep Number, you know finding the right sheets is a real challenge. I’m comparing two popular 100% cotton options: the Peace Sleep Bedding set and the SKY BEDDINGS set, both boasting a 600 thread count.
This comparison is for anyone who needs a 34-inch split head king sheet set. The key difference comes down to pocket depth and subtle feel. Let’s see which one deserves a spot on your mattress.

On paper, they’re very similar, but the pocket depth is the major differentiator. SKY BEDDINGS wins that category hands down for thicker mattresses.
Individual Product Breakdown
I looked at the feel, fit, and real owner feedback for each set. Here’s my honest take on who each one is really for.

This is a solid, no-fuss sheet set that gets the job done. The 600-thread-count sateen weave feels soft and has a nice sheen, and I appreciate that it’s 100% Egyptian cotton. It’s best for someone with a standard-thickness mattress, as the 8-inch pocket depth is its main limitation. The customer rating of 4.4 stars from 67 reviews suggests most people are happy with the quality for the price.
✅ Pros
- High 4.4-star rating from verified buyers
- True 100% Egyptian cotton construction
- Sateen weave feels soft and smooth
- Available in six different color options
❌ Cons
- 8-inch pocket depth won’t fit thicker mattresses
- Fewer total reviews than the competitor

- EGYPTIAN COTTON SHEET & PILLOWCASE SETS - Our cooling bed sheets are crafted...
- CRAFTED FOR PERFECT FIT - Our Top Split King bed sheets set includes: 1 top...
- LUXURIOUS QUALITY BEDDING SHEETS: We have crafted these sheets Super Soft...
This set wins my top pick because it solves the biggest problem with adjustable beds: fitting a thick mattress topper. The 16-inch deep pocket is a big improvement and the main reason to choose it. The 600-thread-count sateen cotton feels luxurious and breathable. It’s the best choice for anyone with a pillow-top mattress, a thick mattress pad, or a bed over 12 inches tall. With 112 reviews, it’s also the more tried-and-tested option.
✅ Pros
- 16-inch deep pocket fits the thickest mattresses
- Larger pool of user feedback with 112 reviews
- Excellent breathability and cooling from sateen weave
- Generous flat sheet size at 108″ x 102″
❌ Cons
- Slightly lower average rating at 4.3 stars
- Some may find the sateen weave too silky
Which One Should You Buy?
Choosing between these two isn’t about one being universally better. It’s about which one solves your specific bed setup problem. Your mattress thickness is the deciding factor.
Peace Sleep Bedding Split Top King Sheets is right for you if…
- Your mattress (or mattress + topper) is 8 inches thick or less.
- You prioritize a slightly higher user rating (4.4 stars) and want a classic cotton feel.
- You want more color choices, as it comes in six options including white and beige.
SKY BEDDINGS Split Top King Sheet Set is right for you if…
- You have a thick mattress, pillow top, or a hefty mattress pad (up to 16 inches).
- You value a larger sample size of reviews, with over 112 customer ratings.
- You want the extra security of a deep pocket that won’t pop off the corners.
❌ Who Should Skip All of These?
If you don’t have a split-top adjustable bed, these sheets are pointless for you. Also, if you strongly prefer a crisp percale weave over a silky sateen, you should look for a different material type entirely.
For most people with an adjustable bed, I recommend the SKY BEDDINGS set. The 16-inch pocket depth is just more versatile and future-proof, ensuring a snug fit on almost any mattress setup.
Frequently Asked Questions
Which split king sheets are better for a thick mattress?
The SKY BEDDINGS set is definitively better for a thick mattress. Its fitted sheet has a 16-inch deep pocket, while the Peace Sleep Bedding set only has an 8-inch pocket. If your mattress, topper, or pad combo is over 8 inches tall, the Peace Sleep sheets simply won’t fit securely. Go with SKY BEDDINGS for anything thicker than a standard mattress.
Are both sheet sets really 100% cotton?
Yes, both sets are made from 100% Egyptian cotton with a 600 thread count and a sateen weave. The core material quality is identical, which is why the feel and breathability are so similar. The main difference isn’t the fabric, it’s the construction of the fitted sheet pocket depth.
Which brand has better customer reviews?
Peace Sleep Bedding has a slightly higher average rating at 4.4 stars from 67 reviews. SKY BEDDINGS has a 4.3-star average, but from a larger pool of 112 reviews. I’d say SKY BEDDINGS has more verified user feedback, while Peace Sleep has a marginally higher satisfaction score among its smaller group of buyers.
Do I need a flat sheet with these sets?
Yes, both are 4-piece sets that include one flat sheet. The Peace Sleep flat sheet measures 102″ x 108″, and the SKY BEDDINGS flat sheet is 108″ x 102″. The SKY BEDDINGS flat sheet is slightly more generous in width, which can be helpful for tucking in on an adjustable bed frame.
Which one is more likely to shrink in the wash?
Both are 100% cotton, so some minimal shrinkage is always possible with any cotton product. However, both manufacturers specify they are resistant to shrinking and fading. To minimize risk, follow the care instructions: machine wash cold or warm and tumble dry on low. I didn’t notice a significant difference in shrinkage potential between them.
Is the higher pocket depth worth choosing SKY BEDDINGS?
Absolutely, if your mattress needs it. The 16-inch pocket is the single most practical advantage in this comparison. An 8-inch pocket is fairly standard and can struggle with modern mattresses. Unless you have a very slim profile bed, the SKY BEDDINGS set offers much more security and is the smarter, more versatile buy.
My Final Verdict
SKY BEDDINGS is my clear winner for the best split king sheets. Its 16-inch deep pocket is a massive practical advantage over the 8-inch pocket on the Peace Sleep set, ensuring a secure fit on virtually any mattress. While both use excellent 600-thread-count Egyptian cotton, the SKY BEDDINGS set is simply the more versatile and reliable choice. The Peace Sleep Bedding set is a fine runner-up, but only if you have a very thin mattress profile.
If you’re on the fence, let your mattress thickness decide. Measure from the top of your mattress to the bottom of any topper. If it’s over 8 inches, the choice is made for you: get the SKY BEDDINGS set. The deeper pocket is worth it for peace of mind alone.
