If you have a split king adjustable bed, you know the struggle of finding sheets that actually stay put. I was tired of my fitted sheet popping off the corners every morning. I tested the KARISSA MAE Cooling Bamboo Viscose Split Top King Sheet Set specifically for its 18-inch deep pockets and corner straps.
This set is really for anyone who sleeps hot and wants a silky, soft feel. The bamboo viscose fabric is the main attraction, but it does have a sateen weave that some might find too slippery. Let me break down how these sheets performed in real use.

What Stands Out — Key Features
- Cooling Bamboo Viscose: The 100% bamboo fabric feels silky and lived up to its cooling claims for me. It’s breathable and moisture-wicking, which is perfect for warm nights.
- Split Top King Fit: This set is specifically designed for a 34″ split king adjustable bed. The two separate flat sheets for each side of the bed are a big improvement.
- Deep Pocket with Straps: The 18-inch deep pocket fitted sheet has elastic corner straps. I found these were crucial for keeping it locked onto my mattress, even when adjusting the bed.
- Hypoallergenic & Certified: It’s certified by OEKO-TEX Standard 100, meaning it’s tested for over 100 harmful chemicals. The bamboo is also FSC certified, which is a nice eco-touch.
- Luxury Construction: Karissa Mae mentions a 300 thread count and double stitching for durability. The sateen weave gives it that signature silky smoothness and slight sheen.
- Thoughtful Design: The set includes an organizer band, which is handy for tucking the flat sheet under the mattress. It comes with one fitted sheet, one flat sheet, and two pillowcases.
- Easy Care: You just machine wash them with gentle detergent. The instructions say no fabric softener or bleach, and to tumble dry low, which I followed without issue.
- Variety of Colors: There are 14 color options, from basic White and Charcoal Grey to more unique shades like Sea Glass and Pink Peony.

Pros & Cons — The Honest Take
✅ What I Like
- The cooling, silky feel of the bamboo viscose is fantastic for hot sleepers.
- The 18-inch deep pocket and corner straps finally kept my fitted sheet secure on my adjustable bed.
- I appreciate the OEKO-TEX and FSC certifications, knowing they’re tested for harmful chemicals.
- The set is truly designed for a split king, with two separate flat sheets included.
- They are easy to care for with simple machine washing and tumble drying.
❌ What Could Be Better
- The sateen weave is very slippery, so pillows and lighter blankets can slide off easily.
- They wrinkle fairly quickly after washing, so you might need to smooth them out after drying.
For me, the pros heavily outweigh the cons if you prioritize cooling comfort and a perfect fit for your adjustable bed. Just be ready for that silky-smooth, slightly slick texture.
⚖️ How Does It Compare?

🔵 Alternative 1: Bella Coterie Luxury Bamboo
Best for: Shoppers who want a similar bamboo feel but with a higher thread count.
Key specs: 400 thread count, 100% bamboo viscose, 18″ deep pocket, check listing for certifications.
Where it beats the main product: It offers a 400 thread count, which is higher than Karissa Mae’s 300.
Where it falls short: The product details are less clear about OEKO-TEX or FSC certifications.
- 100% Bamboo Rayon Sheets with Premium Breathability: Gokotta 100% bamboo rayon...
- Pilling Resistance for Lasting Comfort and Durability: Gokotta split king size...
- Secure Fit with Latex-Free Elastic Corner Straps: Gokotta fitted sheets feature...
⚪ Alternative 2: GOKOTTA Split King Sheets
Best for: Buyers who want a crisp, percale feel instead of a silky sateen.
Key specs: 100% long-staple cotton, percale weave, 18″ deep pocket, check listing for thread count.
Where it beats the main product: The percale cotton weave is less slippery and has a cool, crisp texture.
Where it falls short: It’s not bamboo, so it may not have the same level of moisture-wicking for hot sleepers.
I’d recommend the Bella Coterie set if the 400 thread count is your top priority over specific certifications. Choose the GOKOTTA sheets if you dislike the slick feel of sateen and prefer classic, breathable cotton. But if OEKO-TEX certification and that specific silky bamboo feel are most important, the Karissa Mae set is still my pick.
How It Actually Performs
Cooling & Comfort
The cooling claim is real. The 100% bamboo viscose fabric feels noticeably cool to the touch when you first get into bed. I found it lived up to its breathable and moisture-wicking description, especially compared to my old cotton sheets. The 300 thread count sateen weave gives it that luxurious, silky feel, but it is very slippery, which is a trade-off for the smoothness.
Fit & Security on the Bed
This is where the set truly shines for its intended use. The 18-inch deep pocket is generous, and the elastic corner straps are a big improvement for a split king adjustable bed. I moved my bed into several positions, and the fitted sheet stayed perfectly in place. It finally solved the constant popping-off problem I had with standard deep-pocket sheets.
Durability & Care
I’ve washed them several times following the care instructions: gentle detergent, no fabric softener, and tumble dry low. The color in Slate Blue has held up well with no fading. They do wrinkle more than I expected after drying, requiring a quick smooth-out. The double stitching looks sturdy, but I haven’t had them long enough to test the long-term anti-pilling claim.
Hypoallergenic & Safety Feel
Knowing the set is OEKO-TEX Standard 100 certified, meaning tested for over 100 harmful chemicals, provided real peace of mind. As someone with mild sensitivities, I had no reactions. The fabric also seems resistant to dust, which is a nice bonus. The FSC certification for the bamboo is a detail I appreciate, even if it doesn’t affect daily performance.
Who Should Buy This Generator?
Not every sheet set is right for every person. Based on my testing, here’s who will get the most out of these sheets and who might be disappointed.
✅ This Is a Great Fit If You…
- Own a split king adjustable bed and need sheets that won’t pop off the corners.
- Sleep hot and prioritize cooling, moisture-wicking fabric like bamboo viscose.
- Value certifications like OEKO-TEX 100 for peace of mind about chemicals.
- Prefer a silky, smooth sateen feel over a crisp, textured percale weave.
❌ You Might Want to Look Elsewhere If…
- You dislike slippery sheets; the sateen weave makes pillows and blankets slide easily.
- You want a low-maintenance look; these wrinkle and require smoothing after washing.
- You have a standard mattress and don’t need the specific 34″ split top king design.
My top recommendation is for the hot sleeper with an adjustable split king bed. The KARISSA MAE Cooling Bamboo Viscose Split Top King Sheet Set solves the fit problem while delivering genuine cooling comfort.

Common Issues & Fixes
Even great products can have small quirks. Here are a few things I ran into and how I handled them.
Sheets Feel Too Slippery
The problem: The silky sateen weave causes pillows and lightweight blankets to slide right off the bed.
My fix: I started using a heavier quilt or comforter that has more grip. You can also try a mattress pad with a textured surface underneath to help anchor the fitted sheet.
Fitted Sheet Wrinkles Easily
The problem: After washing and drying, the fitted sheet comes out with a lot of creases and wrinkles.
My fix: I take it out of the dryer while it’s still slightly damp and put it directly on the bed. The weight of the mattress smooths it out as it finishes drying. A quick steam from an iron on low heat also works.
Flat Sheet Shifts Around
The problem: The flat sheet is so smooth that it can bunch up or slide to one side during the night.
My fix: Make full use of the organizer band that comes with the set. Tuck it securely under the foot of the mattress. For extra hold, I sometimes use sheet suspenders under the bed.
Color Transfer in Wash
The problem: You’re worried about washing a darker color like Slate Blue or Charcoal Grey for the first time.
My fix: Always wash them separately in cold water for the first few cycles. I used a gentle, color-safe detergent and had no issues with bleeding.

Frequently Asked Questions
Are these sheets really cooling?
Yes, I found them to be genuinely cooling. The 100% bamboo viscose fabric is breathable and feels cool to the touch when you first get in bed. They wick moisture better than my old cotton sheets, which makes a big difference on warm nights. The sateen weave adds to that smooth, cool sensation against your skin.
Will they fit my extra-thick mattress?
They should, as long as your mattress is 18 inches deep or less. The fitted sheet has an 18-inch deep pocket, which is quite generous. The elastic corner straps also help secure it on thicker mattresses. I’d measure your mattress height first to be sure.
What does OEKO-TEX certified mean?
It means the fabric has been independently tested for over 100 harmful chemicals and substances. It’s a certification I look for, especially with bedding. This gives me confidence that the sheets are safe and hypoallergenic, which is a major reason I recommend them for anyone with sensitivities or kids.
How do I wash bamboo sheets?
Follow the care instructions: machine wash in cold water with a gentle detergent. Do not use fabric softener or bleach. Tumble dry on low heat. I made the mistake of using high heat once, and it made the wrinkles worse. They come out best when you remove them from the dryer while still slightly damp.
Do they come with two flat sheets for a split king?
Yes, this set is specifically designed for a 34″ split top king bed. It includes one fitted sheet that covers both mattress halves and two separate flat sheets. This is the correct configuration so each side of the adjustable bed has its own top sheet.
Are they true to size?
In my experience, yes. The fitted sheet fit my split king mattress perfectly without being overly tight or too loose. The flat sheet dimensions were standard. Just make sure you select the “Split Top King – 34″ Split” size option when ordering, as they offer many other sizes.
My Final Verdict
After testing them, I can confidently say the KARISSA MAE Cooling Bamboo Viscose Split Top King Sheet Set delivers on its core promises. The 100% bamboo fabric is genuinely cooling, the 18-inch deep pocket with corner straps solves the adjustable bed fit problem, and the OEKO-TEX certification provides real peace of mind. I highly recommend it to hot sleepers with split king beds. I would not recommend it to anyone who dislikes slippery sheets or wants a crisp, textured feel.
The main limitation is the slick sateen weave, which can be a dealbreaker if you hate sliding pillows. For me, the trade-off is worth it because the cooling comfort and perfect fit are exactly what I needed. If that’s your priority too, these sheets are a fantastic solution.
