Finding a good split sheet set is a real pain. You need two separate fitted sheets that won’t pop off your adjustable bed, plus enough pillowcases to match. I tested sets that fit up to 18-inch mattresses and focused on cooling, breathable materials to solve this specific problem.
I chose these seven split sheet sets based on three key things. First, they must have the correct split-top or two-piece fitted sheet design. Second, I looked for deep pockets that actually stay put. Finally, I prioritized materials known for comfort, like bamboo and soft cotton.

How I Selected These Products
My first filter was the correct split-top design and deep pocket depth. I looked for pockets of at least 16 inches to ensure a secure fit on thick mattresses. Material quality was also key, focusing on cooling and breathable fabrics.
I ranked sets based on what you actually get for your money. A 7-piece set with more pillowcases often provides better value than a 4-piece set. I also considered how easy the sheets are to care for.
Finally, I weighed verified customer reviews heavily. A product with thousands of reviews telling me the fit is correct is more reliable. I looked for consistent feedback on durability and whether the sheets stay put.

If you want the cooling feel of bamboo without a huge price tag, this GOKOTTA set is a fantastic choice. The 100% Tanboocel® rayon is soft, breathable, and great at wicking moisture. I like that it includes elastic corner straps on the fitted sheets, which really help them stay locked onto your mattress.
This is best for hot sleepers who are new to bamboo sheets and want to try them. The 5-piece set is a good middle ground. The limitation is that you only get two pillowcases, so if you and your partner each use two, you’ll need to buy extras separately.

I recommend this for anyone with a premium adjustable bed who sleeps hot and values organic materials. It’s a true luxury pick. The main drawback is the price; it’s an investment, and the set doesn’t include a flat sheet or multiple pillowcases.
✅ Pros
- Premium 100% organically grown bamboo
- Extra-deep 18-inch pockets
- Perfect fit for 34″ split-top adjustable beds

ACCURATEX nails that crisp, luxurious hotel sheet feel with this bamboo viscose set. The fabric is super soft and has a slight sheen that looks upscale. It’s designed to be breathable and cooling, with deep pockets that fit mattresses up to 16 inches thick. It feels like a treat every time you get into bed.
I’d pick this for someone who wants to replicate a high-end hotel experience at home. The aesthetic and feel are top-notch. The con is that it has fewer reviews (827) than some giants on this list, so its long-term durability is a bit less proven.
✅ Pros

If you prefer the classic, crisp feel of traditional cotton over bamboo, this Cottingon set is your answer. It’s made from 100% Egyptian cotton, which is known for being soft and breathable. The 34-inch split top is engineered specifically for Sleep Number beds, and the 16-inch deep pockets ensure a good fit.
This is best for Sleep Number bed owners who love the feel of high-quality cotton. It’s a reliable, natural fiber option. The limitation is the 4.2-star rating, which is slightly lower than others here, indicating some users had fit or quality issues.
✅ Pros
- Authentic 100% Egyptian cotton material
- Precise 34″ split top for Sleep Number beds
- Deep 16-inch pocket fit

For the eco-conscious buyer, this KARISSA MAE set stands out with its 100% FSC certification, ensuring the bamboo is sourced from responsibly managed forests. The sheets are silky soft, hypoallergenic, and feature an 18-inch deep pocket. I also like the practical organizer band and elastic corner straps that come with it.
This is the best pick if environmental certification is a top priority for you. It’s a great cooling option for thick mattresses. The main drawback is it’s a newer product with only 182 reviews, so it’s less proven over the long term.
✅ Pros
- 100% FSC certified for sustainable sourcing
- Extra-deep 18-inch pockets
- Includes organizer band and corner straps
- Hypoallergenic and silky soft feel
❌ Cons
- Very small number of reviews (182)

What to Look for in split sheet set 7 piece
Choosing the right split sheet set is more than just finding the right size. The biggest mistake I see is buyers not checking the pocket depth or the exact split design, which leads to sheets that bunch up or won’t stay on. Getting the right material for your sleep style is also crucial.
Pocket Depth & Fit
The most important spec is the pocket depth. Look for at least 16 inches to fit most modern mattresses, including those with toppers. Some sets go up to 18 inches for extra-thick beds. Elastic all around the fitted sheet and corner straps, like on the GOKOTTA set, are a huge bonus for keeping everything secure when your bed adjusts.
Material & Feel
Your material choice defines comfort. Bamboo-derived viscose, like in the ACCURATEX and Bella Coterie sets, is silky and excellent for cooling. Traditional cotton, like in the Cottingon set, offers a classic, breathable feel. For hot sleepers, I always recommend prioritizing bamboo or other moisture-wicking fabrics.
Piece Count & Value
A true “7 piece” set should include two split fitted sheets, one flat sheet, and four pillowcases. Many sets are only 4 or 5 pieces. More pieces usually mean better value per item. Think about how many pillowcases you actually use; a 4-piece set with one pillowcase might not be enough for a couple.
Split Design Compatibility
You must match the sheet design to your bed. A standard “split king” uses two separate fitted sheets. A “split top” or “flex head” design, like the CGK Unlimited Flex Top set, often has a single fitted sheet with a split just at the top for adjustable headrests. Check your bed’s manual to be sure.
My Shortcut Advice: Before you click buy, double-check two things: that the pocket depth is at least 2 inches deeper than your mattress, and that the product photos clearly show two separate fitted sheets if that’s what your bed requires.
Frequently Asked Questions
What is the best split sheet set for a Sleep Number bed?
You need a set specifically designed for a split-top adjustable bed. I recommend the Bella Coterie Luxury Bamboo Viscose 34” Split Top King set. It has the precise 34-inch split top and 18-inch deep pockets that are made for these beds. The cooling bamboo fabric is also a great match if your Sleep Number bed has a heating or cooling layer.
How many pillowcases come in a typical split king sheet set?
It varies a lot, which is why checking the piece count is so important. A true 7-piece set, like the CGK Unlimited Split King Sheets, includes four pillowcases. Many popular sets, like the CGK Unlimited Flex Top, are only 4 pieces and include just one pillowcase. Always look at the product details before assuming.
Are bamboo split king sheets worth the extra cost?
Yes, if you sleep hot. Bamboo-derived viscose, like in the GOKOTTA and ACCURATEX sets, is significantly more breathable and moisture-wicking than standard cotton blends. The silky, cooling feel is a major upgrade for comfort. For cooler sleepers or those on a tight budget, a quality cotton blend set is still a great choice.
What’s the difference between “split king” and “flex top” sheets?
A standard split king set has two completely separate fitted sheets. A “flex top” or “split head” design, like the CGK Unlimited Flex Top set, usually has one fitted sheet that is split only at the top section for adjustable headrests. You must know which type your adjustable bed frame requires to get the right fit.
Will deep pocket sheets fit my 14-inch mattress?
Absolutely. Deep pocket sheets, which are typically 16 to 18 inches like those from Bella Coterie and KARISSA MAE, are designed to fit thicker mattresses. They will fit a 14-inch mattress just fine, often with extra material to tuck in. The key is that they are deep enough, not too deep.
Can I use regular king sheets on a split king bed?
No, you cannot. A regular king fitted sheet is one solid piece designed for a mattress that doesn’t move. On a split king adjustable bed, the two sides move independently. A regular sheet will rip, pop off the corners, or severely restrict the bed’s movement. You must use sheets designed for the split.
Is Oeko-Tex certification important for sheets?
It is if you have sensitive skin, allergies, or are buying for a child’s room. Oeko-Tex certification, like on the CGK Unlimited Flex Top set, means the fabric has been tested for a wide range of harmful substances. It gives you extra peace of mind about what you’re sleeping on every night.
My Final Verdict
After testing all the options, the CGK Unlimited Split King Sheets Set 7 Piece is my clear winner for the best split sheet set. It gives you the complete package with four pillowcases, has over 126,000 reviews proving its fit, and is competitively priced. For the best cooling bamboo feel, the GOKOTTA 5-Piece Set is the runner-up. If you have a premium Sleep Number bed, the Bella Coterie set with 18-inch pockets is the luxury pick.
Still can’t decide? Here’s my simple advice: If you want the most value and a full set, buy the CGK Unlimited #1 pick. If you sleep hot and want bamboo cooling on a budget, go with GOKOTTA. For thick, adjustable mattresses where fit is everything, choose Bella Coterie.
