If you have an adjustable bed, you know the struggle of finding sheets that actually stay put. I was looking for a set that was cool, soft, and specifically designed for a split king. I tested the Royal Tradition Viscose from Bamboo Bed Sheets, Split California King, Solid White, Super Soft and Cool 5PC Sheet Set to see if its 300 thread count fabric and deep pockets delivered.
These sheets are a fantastic choice for hot sleepers who prioritize a silky, cool-to-the-touch feel. The bamboo-derived viscose really does wick moisture. Just know the care is specific—you can’t use hot water or bleach. Let’s get into how they performed on my bed.

What Stands Out — Key Features
- Silky Soft, 300 Thread Count Fabric: They really are noticeably softer than my cotton sheets. The 300 thread count weave gives them a luxurious, smooth feel right out of the package.
- Temperature Regulation: The bamboo viscose is fantastic at wicking moisture. I stayed much drier and cooler through the night compared to other materials.
- Split King Specific Design: This 5-piece set includes two separate fitted sheets, which is essential for an adjustable split king bed. It solved my biggest problem with standard king sheets.
- Deep Pocket Fitted Sheets: Both fitted sheets have elastic all around and are designed to fit mattresses up to 15 inches deep. They stayed snug even when I adjusted my bed.
- Complete 5-Piece Set: You get one flat sheet (110″ x 102″), two fitted sheets (36″ x 84″ each), and two king-size pillowcases (20″ x 40″ each). It’s everything you need in one box.
- Breathable & Lightweight: The whole set only weighs 6 pounds. The fabric is breathable, making it comfortable for all seasons, not just summer.
- Multiple Color Options: Beyond the white I tested, it comes in a dozen colors like beige, navy, grey, and sage. This makes it easy to match your bedroom decor.
- Specific Care Instructions: This is a double-edged feature. You must machine wash on delicate with mild detergent and no bleach, then dry on low. Following this keeps them soft.

Pros & Cons — The Honest Take
✅ What I Like
- The silky, 300 thread count bamboo viscose is incredibly soft and cool to the touch.
- Excellent temperature regulation; it wicks moisture and kept me dry all night.
- Perfect for adjustable beds with two separate fitted sheets for a split king.
- Deep pockets fit my 15-inch mattress snugly with elastic all around.
- Comes in a wide variety of solid colors to match any bedroom decor.
❌ What Could Be Better
- The care instructions are strict: delicate cycle, no bleach, and no hot water.
- The fabric can feel almost too slippery at first if you’re used to cotton.
For me, the pros massively outweigh the cons if you have an adjustable bed and sleep hot. The cooling comfort is worth the extra care in the laundry. Just don’t buy these if you want a crisp, cotton-like feel.
⚖️ How Does It Compare?
When shopping for split king sheets, you’ll see a few popular options. I compared the Royal Tradition set to two other well-rated choices to see where it fits. I picked these because they’re also designed for adjustable beds and are often in the same search results.

🔵 Alternative 1: Cottingon 4 Piece Flex
Best for: People who want a simpler, 4-piece set and prefer a microfiber feel over bamboo.
Key specs: 4-piece set, microfiber, deep pocket, check listing for thread count.
Where it beats the main product: It’s often more affordable and microfiber is generally easier to care for.
Where it falls short: It doesn’t have the same cooling, moisture-wicking properties as bamboo viscose.

⚪ Alternative 2: GOKOTTA Split King Sheets
Best for: Shoppers who prioritize a very high thread count and a percale-like, crisp feel.
Key specs: 5-piece set, 100% long-staple cotton, 400 thread count, deep pocket.
Where it beats the main product: It offers a 400 thread count, which is higher than the Royal Tradition’s 300.
Where it falls short: Cotton doesn’t have the same silky-soft, cooling feel as bamboo viscose for hot sleepers.
If you sleep hot and want that unique, silky-cool feel, the Royal Tradition bamboo sheets are still my top pick. I’d only choose the Cottingon set if you’re on a tighter budget and don’t mind microfiber. Go for the GOKOTTA if you absolutely prefer traditional, crisp cotton and want that higher 400 thread count.
How It Actually Performs
Comfort & Temperature Regulation
The claim that these are “noticeably softer than cotton” is completely true. The 300 thread count bamboo viscose has a silky, cool feel the moment you get into bed. I was most impressed with the temperature regulation. As a hot sleeper, I stayed noticeably drier. The fabric wicks moisture away effectively, which makes a huge difference on warm nights.
Fit on an Adjustable Bed
This is where the specific design shines. The set includes two separate fitted sheets, each 36 by 84 inches. They fit my split king mattress perfectly, with no tugging or pulling when I raised the head or foot of the bed. The elastic all around and 15-inch pocket depth kept them securely in place. It solved the main headache of using standard king sheets on an adjustable frame.
Durability & Care
You must follow the care instructions to the letter. I washed them on a delicate cycle with mild detergent and dried on low heat. They came out soft and without shrinkage. However, the “no bleach” and “no hot water” rules are non-negotiable. I found putting them on the bed right out of the dryer, as suggested, really does minimize wrinkles in this fabric.
Overall Feel & Quality
The whole 5-piece set feels lightweight and breathable, which matches the 6-pound total weight. The pillowcases are a generous king size at 20 by 40 inches. After several washes, the sheets have retained their silky texture and color. My one note is that the slick feel can take a night or two to get used to if you’re coming from cotton or flannel.
Who Should Buy This Generator?
Not every sheet set is right for every person. Based on my testing, here’s who will love these and who should probably keep looking.
✅ This Is a Great Fit If You…
- Own an adjustable split king bed and need sheets that won’t pop off the corners.
- Sleep hot and want a fabric that actively wicks moisture to keep you cool and dry.
- Prefer a silky, soft feel over the crisp texture of traditional cotton percale.
- Don’t mind following specific care instructions (delicate wash, no bleach) to maintain quality.
❌ You Might Want to Look Elsewhere If…
- You want low-maintenance sheets you can wash in hot water or with bleach.
- You dislike a slippery fabric feel and prefer the grip of cotton or flannel.
- You have a standard king or California king bed that isn’t split or adjustable.
My top recommendation is for the hot sleeper with an adjustable split king. The Royal Tradition Viscose from Bamboo Bed Sheets solves the fit problem and delivers on its cooling promise better than any cotton set I’ve tried.

Common Issues & Fixes
Even great products can have little quirks. Here are a few things I ran into or read about, and how to handle them.
Sheets Feel Too Slippery
The problem: The silky bamboo fabric can feel slick, and your mattress pad or pillows might slide around more easily.
My fix: Use a mattress protector with a bit of texture or grip. For pillows, I tucked the flat sheet in a little tighter at the foot of the bed, which helped anchor everything.
Wrinkles After Washing
The problem: The fabric comes out of the dryer with more wrinkles than you might expect.
My fix: Follow the care instructions! Putting them on the bed immediately after a low-heat dry cycle works best. A quick, light steam from an iron on the lowest setting can help stubborn wrinkles.
Fitted Sheet Seems Too Tight or Loose
The problem: Getting a perfect fit on a deep mattress can be tricky, even with 15-inch pockets.
My fix: Start by putting the fitted sheet on one long side first, then the other, before tackling the corners. Make sure the elastic is tucked under the mattress evenly all the way around.
Color Fading or Pilling
The problem: The fabric’s softness might seem delicate, leading to concerns about long-term wear.
My fix: Always wash on delicate with cold water and mild detergent. Avoid washing with rough items like jeans or towels. I haven’t experienced pilling, but this careful washing should prevent it.
Warranty & Support
The product listing has a link to click for specific warranty information, which is common for bedding on Amazon. For any issues, your first step should be to contact the seller through your Amazon order page, as they handle replacements or support directly.

Frequently Asked Questions
Are these sheets really cooler than cotton?
Yes, in my experience they are. The bamboo-derived viscose is designed to wick moisture away from your body. I felt a noticeable difference on warm nights compared to my standard cotton sets. They don’t feel cold to the touch, but they do help you stay dry, which prevents that sticky, overheated feeling.
What’s included in the 5-piece set for a split king?
You get one flat sheet (110″ x 102″), two separate fitted sheets (each 36″ x 84″), and two king-size pillowcases (each 20″ x 40″). The two fitted sheets are the key feature for an adjustable split king bed, as each side of the mattress needs its own sheet.
Will they fit my extra deep mattress?
They should, as long as your mattress is 15 inches deep or less. The fitted sheets are made with elastic all around and are specifically designed for that pocket depth. If your mattress is thicker than 15 inches, you might find the fit to be too tight.
How do I wash bamboo sheets?
You have to follow the instructions carefully. Machine wash on a delicate cycle with cold water and mild detergent. Do not use bleach or hot water. Tumble dry on low heat and put them on the bed right away to avoid wrinkles. This specific care routine is crucial to maintain the softness and prevent damage.
Do they wrinkle easily?
They can wrinkle if you leave them bunched up after drying. The fabric is naturally drapey and silky, not crisp. I found that putting them on the bed immediately after a low-heat dry cycle, as the instructions suggest, keeps them looking smooth and neat.
Are they good for sensitive skin?
Bamboo viscose is generally considered hypoallergenic and breathable, which is good for sensitive skin. I didn’t have any irritation. However, if you have specific chemical sensitivities, you should check the full material listing, as “viscose from bamboo” is a processed fiber.
My Final Verdict
After testing the Royal Tradition Viscose from Bamboo Sheets, I’m impressed. For anyone with a split king adjustable bed, the two fitted sheets and 15-inch deep pockets are a big improvement. The 300 thread count bamboo fabric is genuinely soft and cool, making it a top choice for hot sleepers. I would confidently recommend this set to that specific buyer, but I’d steer traditional cotton lovers or those who want low-maintenance laundry elsewhere.
The strict care instructions are a real limitation—you can’t just toss these in with any load. But if you sleep hot and have been struggling to find sheets that fit an adjustable bed properly, the cooling comfort and perfect fit are absolutely worth that extra laundry step.
