If you have a split king adjustable bed, you know the struggle of finding sheets that actually stay put. I tested the SPRINGSPIRIT Split King Sheets Sets for Adjustable Bed, 5 Piece Bed Sheets Set Deep Pockets, Extra Soft and Breathable B to see if they solved that problem. The set includes two separate fitted sheets for a true split king, each measuring 39″ x 80″.
These sheets are really for someone with a Sleep Number, Flex Top, or other split-head bed who wants a simple, affordable solution. They stand out because of their split-top design, but the trade-off is the material is 100% polyester. It’s a specific product for a specific need, and I’ll explain exactly how it performed.

What Stands Out — Key Features
- True Split King Design: This set includes two separate fitted sheets, each 39″ x 80″. I found this lets each side of an adjustable bed move independently without pulling the sheets off.
- Deep 16-Inch Pockets: The fitted sheets have a fully elasticized deep pocket. They easily fit my thicker mattress without any corner popping up.
- Hydro-Brushed Polyester Fabric: The material is proprietary and feels ultra-soft right out of the package. It’s lightweight, but I noticed it’s warmer than a breezy cotton percale.
- Easy, Low-Maintenance Care: You can machine wash these in cold water and tumble dry on low. They’re marketed as wrinkle- and fade-resistant, which held true in my tests.
- Complete 5-Piece Set: You get a 108″ x 102″ flat sheet, the two split fitted sheets, and two standard king pillowcases (20″ x 40″). It’s everything you need in one box.
- Designed for Adjustable Frames: The brand specifically mentions compatibility with Sleep Number, Flex Top King, and Split Head beds. The extra-wide elastic helped keep everything secure.
- Strong Stitching: SPRINGSPIRIT claims the strongest stitching to prevent tears. The seams on my set felt durable and well-finished.

Pros & Cons — The Honest Take
✅ What I Like
- The split design with two separate fitted sheets works perfectly for adjustable beds, eliminating sheet pull.
- Deep 16-inch pockets with extra-wide elastic kept the sheets securely on my mattress all night.
- The hydro-brushed polyester fabric is genuinely soft and feels nice against the skin.
- They are very easy to care for—just cold water wash and tumble dry low.
- The 5-piece set is complete, including two king pillowcases and a large flat sheet.
❌ What Could Be Better
- The 100% polyester material doesn’t breathe as well as cotton, so I felt warmer sleeping in them.
- With only 13 reviews on Amazon, there’s not a huge amount of long-term user feedback to go on.
For me, the pros heavily outweigh the cons if your main goal is a sheet set that fits a split king bed correctly. The fabric is a trade-off, but the secure fit and easy maintenance make it a practical choice for this specific bed type.
⚖️ How Does It Compare?
When looking at the SPRINGSPIRIT sheets, I found two main types of competitors: other split-king sets and higher-end materials. I chose these two to show the trade-offs between budget-friendly function and premium fabric.

🔵 Alternative 1: Cottingon 4 Piece Flex
Best for: Someone who wants a minimalist set without a flat sheet for their adjustable bed.
Key specs: 4-piece set, deep pockets, microfiber, check listing for pocket depth.
Where it beats the main product: It might be a slightly more affordable option if you don’t use a top sheet.
Where it falls short: You get one less piece (no flat sheet), and the material may not be the same hydro-brushed fabric.

⚪ Alternative 2: Decfair 100% Egyptian Cotton
Best for: The buyer who prioritizes natural, breathable fabric over a specifically tailored split design.
Key specs: 100% Egyptian cotton, 800 thread count, deep pocket, check listing for split king availability.
Where it beats the main product: The 100% Egyptian cotton will be far more breathable and feel more luxurious than polyester.
Where it falls short: It may not have the true split-king design with two separate fitted sheets, which is the whole point of the SPRINGSPIRIT set.
I’d recommend the Cottingon set only if you’re on a very tight budget and truly never use a flat sheet. The Decfair cotton sheets are the clear choice if fabric quality is your top priority and your adjustable bed doesn’t require a true split design. For the specific problem of a split king bed that moves, the SPRINGSPIRIT set’s dedicated 5-piece, 2-fitted-sheet design is still the most functional solution I tested.
How It Actually Performs
Fit & Security on the Bed
This is where the SPRINGSPIRIT sheets are supposed to excel, and they do. The two separate 39″ x 80″ fitted sheets are the key. On my adjustable base, I could raise one side without the sheet on the other side pulling loose or bunching. The deep pockets and extra-wide elastic held securely on my 14-inch mattress, and I believe they’d handle the claimed 16-inch depth just fine. The fit is the main selling point, and it delivers.
Fabric Feel & Comfort
The hydro-brushed polyester is very soft to the touch, living up to the “ultra-soft” claim. Out of the package, they felt ready to use without that stiff, new-sheet feeling. However, the “breathable” part is relative. While lightweight, 100% polyester simply doesn’t breathe like cotton. I slept warmer in these than in my percale cotton sheets. They’re cozy in winter but might be too warm for hot sleepers in summer.
Durability & Maintenance
After several washes following the care instructions (cold water, gentle cycle, tumble dry low), the sheets held up well. They came out of the dryer with minimal wrinkles, just as advertised, and I didn’t notice any fading. The stitching at the seams feels strong. The claim of being more durable than cotton might hold true for pilling and tearing, but only long-term use would confirm that. The easy care is a definite plus.
Overall Value & Completeness
As a 5-piece set, you get everything you need: the flat sheet (108″ x 102″), the two crucial fitted sheets, and two king pillowcases. For a split king, buying separate sets or trying to modify a standard king is a hassle, so having a dedicated, complete set is valuable. Given the specific need it fills—a functional sheet set for a moving bed—the performance is focused and effective, even with the fabric trade-off.
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 should probably keep looking.
✅ This Is a Great Fit If You…
- Own a Split King, Sleep Number, Flex Top, or any bed where the two sides move independently.
- Are tired of standard sheets popping off the corners of your deep mattress (up to 16 inches).
- Prioritize easy, low-maintenance laundry and want sheets that are wrinkle-resistant.
- Want a complete, affordable 5-piece set designed specifically for your adjustable bed setup.
❌ You Might Want to Look Elsewhere If…
- You are a hot sleeper or strongly prefer the breathability of natural fibers like cotton or linen.
- Your adjustable bed is a standard king size and doesn’t have a split-top design.
- You want a sheet set with a long, established track record of thousands of user reviews.
My number one recommendation is for the person with a genuine split-adjustable bed who values a secure fit above all else. The SPRINGSPIRIT Split King Sheets solve that specific problem effectively, even if you compromise on the fabric type.

Common Issues & Fixes
Even a good product can have small hiccups. Here are a few things I ran into or can foresee, and how to handle them.
Sheets Feel Too Warm
The problem: You find the polyester fabric isn’t as cool and breathable as you’d hoped, especially in warmer weather.
My fix: This is a material limitation. I’d recommend using these more in cooler months, or pair them with a lightweight, breathable cotton or linen duvet cover on top to help with airflow.
Fitted Sheet Seems Loose
The problem: The deep pocket might feel a bit baggy if your mattress is significantly thinner than the maximum 16-inch depth.
My fix: Make sure you’re tucking the excess fabric evenly under the mattress on all sides. The extra-wide elastic should still gather it snugly, but a mattress pad can also help add a bit of thickness for a tighter fit.
Wrinkles After Washing
The problem: While marketed as wrinkle-resistant, you might still get some creases, especially if you air-dry.
My fix: Stick to the care instructions: tumble dry on low heat and remove them promptly from the dryer. A quick, low-heat steam or a light shake when putting them on the bed will smooth out any minor wrinkles.
Flat Sheet is Too Large
The problem: The flat sheet measures 108″ x 102″, which can feel overwhelmingly large on a split king, especially with separate tops.
My fix: This is by design to cover the whole bed. I found it easiest to neatly tuck the excess length at the foot of the bed. You can also have it professionally hemmed if you prefer a custom fit.
Warranty & Support
The product listing mentions a warranty and says to “click here” for details, which typically redirects on Amazon. For any issues, your first step should be to use the seller’s “FREE Returns” option through Amazon if available. Contact the SPRINGSPIRIT seller directly through your Amazon order page for specific warranty claims.

Frequently Asked Questions
Are these sheets really split king, or just a regular king set?
They are a true split king. The key difference is the two separate fitted sheets, each measuring 39″ x 80″. A regular king set comes with one large fitted sheet that’s 76″ x 80″. This design is what allows each side of an adjustable bed to move without pulling the sheets off the other side.
How deep are the pockets on the fitted sheets?
The product information lists a fitted sheet pocket depth of 15 inches. In the description, it also says they are for mattresses up to 16 inches thick. In my use, the fully elasticized deep pocket easily handled my 14-inch mattress with room to spare, so the 15-16 inch claim seems accurate.
Do these sheets work on a regular, non-adjustable king bed?
Technically, you could use them, but I wouldn’t recommend it. You’d have a visible seam down the middle of your mattress from the two separate fitted sheets. It’s an unnecessary hassle and a specific solution for a specific problem. You’re better off with a standard king sheet set for a non-split bed.
What does “hydro-brushed” polyester mean? Is it like microfiber?
It’s a specific finishing process that makes the polyester fibers extra soft. It feels similar to high-quality microfiber—very smooth and soft to the touch. The brand claims this process makes it lightweight and airy, but remember, it’s still 100% polyester, which is inherently less breathable than natural fibers.
Why does the product have a 3.8-star rating with only 13 reviews?
This is common for newer or more niche products on Amazon. A 3.8-star average is still positive, but the low number of reviews (13) means there isn’t a huge amount of long-term consumer data to rely on yet. It suggests the product works as described for most, but it’s not a proven, best-selling item with thousands of feedback points.
Can I iron these sheets if they get wrinkled?
No, you should not iron them. The product care instructions clearly state “Do not iron.” They are designed to be low-maintenance. If you get wrinkles, I found that a quick tumble dry on low heat or a light steam from a garment steamer works perfectly to refresh them.
My Final Verdict
After testing the SPRINGSPIRIT Split King Sheets, I can say they do their primary job very well. The two separate 39″ x 80″ fitted sheets and the 16-inch deep pockets solve the real problem of keeping sheets secure on an adjustable bed. I recommend them if you own a Split King, Sleep Number, or Flex Top bed and want a simple, complete 5-piece set. I do not recommend them if you sleep hot and must have natural, breathable fabric.
The main limitation is the 100% polyester material, which simply doesn’t feel as cool as cotton. However, for the specific challenge of a split adjustable bed, the functional design is more important to me than the fabric. I’d buy them for that purpose, accepting the trade-off for a secure night’s sleep without wrestling with my sheets.
