Individual Product Breakdown
I tested each set for feel, fit, and durability. Here’s my honest take on who will love each one and what you should know before buying.
California Design Den Split King Sheets Sets for Adjustable Bed – Buttery Soft 800 Thread Count

- 5-Piece Split King Sheet Set: Includes 1 king size top sheet (112"W x 102"L...
- Substantial & Buttery: The weightier fabric feels thick, buttery smooth and...
This set lives up to its “buttery soft” name right out of the package. The 800 thread count sateen weave feels substantial and smooth, and it has the Good Housekeeping Seal, which I trust. It’s the best choice for most people because it’s proven, with over 5,800 reviews backing up its quality. The only real limitation is the 15-inch pocket depth, which might not fit the very deepest mattresses.
✅ Pros
- Exceptional 4.5-star rating from 5,809 verified buyers
- Gets softer with every wash, like your favorite jeans
- Includes head/foot tags to make bed-making easier
- OEKO-TEX and Good Housekeeping certified for safety
❌ Cons
- 15-inch pocket is shallower than the other two options
- 800 thread count is lower than the luxury competitors

- Embrace Substantial Thickness and Weight: Immerse yourself in the luxurious...
If your top priority is a high thread count, this is your best bet. The 1500 thread count Egyptian cotton feels dense and luxurious, with a noticeable cooling effect that’s great for hot sleepers. The 17-inch deep pocket is a real advantage for thicker mattresses. I found it to be competitively priced for true Egyptian cotton, though it has fewer reviews than the California Design Den set.
✅ Pros
- True 1500 thread count Egyptian cotton for a premium feel
- 17-inch deep pocket fits mattresses up to 18 inches thick
- Breathable and cooling fabric, ideal for warm climates
- Mercerized to resist pilling and fading over time
❌ Cons
- Lower customer rating (4.2) than the top pick
- May require ironing to maintain a perfectly smooth look

This set is all about that opulent, hotel-style experience. The 1500 Series Egyptian cotton has a beautiful, luminous sheen from the sateen weave that makes your bed look instantly more expensive. It feels substantial and silky, just like the description promises. It’s perfect if you want the absolute highest thread count and don’t mind paying a bit more for that prestige. Just know it’s the most expensive option of the three.
✅ Pros
- Premium 1500 thread count Egyptian cotton with a gorgeous sheen
- Deep 17-inch pockets ensure a secure fit on thick mattresses
- Single pleat hem on flat sheet adds a tailored, elegant look
- OEKO-TEX certified for safety and free from harmful substances
❌ Cons
- Typically the highest priced option of the three
- Care instructions recommend gentle cycles and separate washes
Which One Should You Buy?
There’s no single “best” sheet set for everyone. Your perfect choice depends on what you value most: proven reliability, maximum thread count, or pure luxury feel. Let me match you with the right one.
California Design Den Split King Sheets is right for you if…
- You trust crowd wisdom and want a set with over 5,800 five-star reviews.
- You prefer a buttery soft feel that gets better with every wash.
- You have a standard mattress depth and want the best value.
TEXAS LINEN CO. 100% Egyptian Cotton Sheets is right for you if…
- You’re a hot sleeper and need the cooling breathability of 1500 TC Egyptian cotton.
- You have a thick mattress up to 18 inches that needs the 17-inch deep pocket.
- You want the highest thread count without paying the top-tier price.
THREAD SPREAD 100% Egyptian Cotton Sheets is right for you if…
- You want that unmistakable, luminous sheen of premium hotel bedding.
- Budget is secondary to getting the most opulent 1500 thread count experience.
- You appreciate details like single pleat hems for a tailored look.
❌ Who Should Skip All of These?
If you’re looking for crisp, cool percale sheets, these sateen weaves aren’t for you. Also, if your mattress is over 18 inches thick, you’ll need to look for specialty extra-deep pocket sheets.
For most people, the California Design Den set is the smartest buy. It delivers incredible softness and durability at a great price, backed by thousands of happy sleepers. You really can’t go wrong with it.
Frequently Asked Questions
Is 1500 thread count Egyptian cotton worth it over 800 thread count?
It depends on your priority. The 1500 thread count from TEXAS LINEN CO. and THREAD SPREAD feels denser and more luxurious, with a noticeable sheen. However, the California Design Den 800 thread count set is incredibly soft, has a higher customer rating (4.5 vs 4.2/4.3), and is often more competitively priced. For most people, the 800 count offers the best balance of feel and value.
Which split king sheets are best for hot sleepers?
I recommend the TEXAS LINEN CO. set for hot sleepers. Its 100% Egyptian cotton and 1500 thread count sateen weave are specifically designed to be breathable and cooling. Both Egyptian cotton options will be cooler than standard cotton, but the TEXAS LINEN CO. set is often priced better than the THREAD SPREAD, making it the smarter cooling choice.
Do these sheets fit an adjustable bed properly?
Yes, all three are specifically designed for adjustable split king beds. Each set includes two separate Twin XL fitted sheets for the split sides. They all have deep pockets with elastic all around to stay secure when you move the bed. The TEXAS LINEN CO. and THREAD SPREAD sets have a slight edge with a 17-inch pocket versus the California Design Den’s 15-inch pocket.
Which brand has the most reliable quality and reviews?
California Design Den has the most proven track record by far. With 5,809 reviews and a 4.5-star average, it’s the most tested and trusted option. The other two sets have good ratings (4.2 and 4.3 stars), but with only 809 and 672 reviews respectively, they don’t have the same volume of long-term user feedback.
Will these sheets shrink or pill over time?
All three brands claim to be tested for pilling and shrinkage. The two Egyptian cotton sets (TEXAS LINEN CO. and THREAD SPREAD) are mercerized, which helps them resist pilling and fading. The California Design Den set is lab-tested for the same issues. With proper cold water washing and low heat drying, you should minimize shrinkage with any of them.
What’s the real difference between TEXAS LINEN CO. and THREAD SPREAD?
Both use 1500 thread count Egyptian cotton sateen with 17-inch pockets. The main differences are price and presentation. THREAD SPREAD markets a more opulent, “7-star hotel” experience and often costs a bit more. TEXAS LINEN CO. is typically more competitively priced. In my testing, the feel is very similar, so I’d choose based on current price and color preference.
My Final Verdict
After testing all three, the California Design Den 800 thread count set is my clear overall winner. Its buttery soft 100% cotton sateen, backed by over 5,800 five-star reviews and the Good Housekeeping Seal, delivers unbeatable value and proven comfort. If you absolutely must have the highest thread count, the TEXAS LINEN CO. 1500 thread count Egyptian cotton is the smarter luxury pick for its cooling feel and 17-inch deep pocket.
If you’re stuck deciding, go with the crowd. The massive number of positive reviews for the California Design Den set is the most reliable indicator you’ll be happy with your purchase. It’s the safest, most satisfying choice for the vast majority of buyers.
