If you have a split-top adjustable bed, you know the struggle of finding sheets that fit. I’m comparing two popular budget options: the Clara Clark Flex Top King 6-piece set and the Royal Bliss 1900 Top Split California King 4-piece set. Both are double-brushed microfiber, but they have different specs and prices.
This comparison is for anyone trying to outfit their adjustable bed without spending a fortune. The main trade-off is between a more complete set and a slightly higher thread count. I tested both to see which one gives you more for your money.

I was impressed by the value of this 6-piece set. The double-brushed microfiber is very soft right out of the package, and the fit on my split-top adjustable bed was perfect. It’s a great choice for anyone who wants a complete bedding set with four pillowcases without spending a lot. My only note is that the 1800 thread count feels good, but the fabric isn’t as dense as some higher-thread-count options.
✅ Pros
- Includes 4 pillowcases for a full 6-piece set
- Excellent value for the price
- High 4.4-star rating from 5,902 reviews
- Fade, stain, and wrinkle resistant for easy care

The Royal Bliss sheets feel a bit more substantial thanks to the 1900 thread count and microfiber-rayon blend. The 20 cm deep pocket is a definite plus if you have a thicker mattress. This set is best for someone who prioritizes a slightly denser, cooler-feeling fabric and doesn’t mind getting only two pillowcases. I found it to be a solid performer, but you are paying more per piece compared to the Clara Clark set.
✅ Pros
- Higher 1900 thread count for a denser fabric
- Specified 20 cm deep pocket for thick mattresses
- Wrinkle and fade resistant, easy to care for
- Good 4.3-star rating from 5,626 reviews
❌ Cons
- Only includes 2 pillowcases in the 4-piece set
- Higher price point for fewer pieces
Which One Should You Buy?
Both of these sheet sets are solid budget options for a split-top bed. The best pick for you comes down to what you value more: a complete set or a slightly finer fabric.
Clara Clark Flex Top King Sheets is right for you if…
- You want the best value and need four pillowcases for a complete 6-piece set.
- You prioritize a high customer rating (4.4 stars from 5,902 reviews).
- You want the most affordable way to outfit your adjustable bed.
Royal Bliss 1900 Top Split Sheets is right for you if…
- You prefer a denser-feeling fabric with a higher 1900 thread count.
- You have a very thick mattress and need the specified 20 cm deep pocket.
- You only need two pillowcases and are willing to pay more per piece.
❌ Who Should Skip All of These?
If you’re looking for natural fibers like cotton, linen, or bamboo, you should skip these. Both sets are made from synthetic microfiber blends, which some sleepers find less breathable.
For most people on a budget, I recommend the Clara Clark set. You get more pieces for your money, and the quality is still very good for the price.
Frequently Asked Questions
Which split king sheets are softer, Clara Clark or Royal Bliss?
Both are double-brushed microfiber and feel soft, but they have a different hand feel. The Clara Clark (1800 thread count) is very soft and smooth. The Royal Bliss (1900 thread count) feels a bit more substantial and dense. For pure, plush softness right away, I give a slight edge to the Clara Clark.
Is the Royal Bliss 1900 thread count worth the extra money over Clara Clark?
Only if fabric density is your top priority. The Royal Bliss has a 1900 thread count versus 1800, which makes it feel a bit more substantial. However, the Clara Clark gives you a 6-piece set with four pillowcases, while Royal Bliss is a 4-piece set with two. For most budget buyers, the Clara Clark offers better overall value.
Do both sheet sets fit a standard split king adjustable bed?
Yes, both are specifically designed for split-top adjustable beds. The Clara Clark is labeled “Flex Top King” and the Royal Bliss is “Top Split California King.” Always double-check your mattress dimensions, but both should fit the split head section of a standard split king or split cal king bed.
Which sheets have deeper pockets for a thick mattress?
The Royal Bliss sheets win for a specified deep pocket. They list a pocket depth of 20 cm (about 7.9 inches). The Clara Clark sheets don’t specify a pocket depth in their product details, though they are fully elasticized. If you have an extra-thick mattress, the Royal Bliss is the safer bet.
How do the care instructions differ between the two?
They are very similar and both easy-care. Clara Clark recommends machine washing in cold water and tumble drying on low, removing promptly. Royal Bliss says to machine wash and specifically advises not to iron. Both are marketed as wrinkle-resistant, so you shouldn’t need to iron either one.
Which set is better for a guest room on a budget?
Hands down, the Clara Clark set. For a guest room, you often want a complete set with pillowcases ready to go. The Clara Clark 6-piece set includes four pillowcases, which is perfect for a king bed with multiple pillows. It’s also the more competitively priced option, which is ideal for a space that isn’t used every night.
My Final Verdict
After comparing them side-by-side, the Clara Clark Flex Top King Sheets are the clear winner for most budget buyers. You get a complete 6-piece set with four pillowcases for a very competitive price, and they still deliver a soft, 1800 thread count fabric with a great 4.4-star rating. The Royal Bliss sheets are a good runner-up if you specifically want the denser 1900 thread count feel and a specified 20 cm deep pocket.
If you’re on the fence, ask yourself what you need more: a full bedding set ready to go, or a slightly finer fabric feel. For 90% of people, the better value and convenience of the Clara Clark set makes it the smarter buy.
