If you’re shopping for split king sheets on a budget, you’ve likely narrowed it down to two popular options: the CGK Unlimited 7-Piece Set and the SPRINGSPIRIT 4-Piece Set. Both are microfiber, promise deep pockets, and are competitively priced, but they offer very different bundles.
This comparison is for anyone trying to decide between a more complete set with two fitted sheets and four pillowcases, or a simpler set with a lifetime guarantee. I’ve tested both to see which one delivers the best value for your money. Let’s break down which set is right for your adjustable bed.

This set is the clear winner for value because it includes everything you need for a split king bed. You get two separate fitted sheets, which is essential for an adjustable base, plus four pillowcases. The 16-inch deep pockets fit thick mattresses easily, and the microfiber is soft right out of the package. It’s the best choice if you want a complete, no-fuss kit. My only gripe is that the warranty details aren’t as prominent as with the competitor.
✅ Pros
- Truly complete 7-piece set with two fitted sheets
- Deep 16-inch pockets for thick mattresses
- Huge number of verified reviews (over 126k)
- Competitively priced for what you get

I was impressed by the confidence behind the SPRINGSPIRIT lifetime guarantee, which is rare at this price point. The 4-piece set is simpler, with one split-head fitted sheet, a flat sheet, and two pillowcases. The microfiber is breathable and the 15-inch pockets held my mattress securely. This is the better pick if you prioritize a strong warranty over having extra pillowcases and a second fitted sheet. Just know you’re buying a more basic bundle.
✅ Pros
- Strong, no-questions-asked lifetime guarantee
- Higher average customer rating of 4.5 stars
- All-around elastic on fitted sheet for a secure fit
- Breathable and soft microfiber material
❌ Cons
- Only one fitted sheet (split-head design)
- Set includes only two pillowcases
- Smaller review pool compared to CGK
Which One Should You Buy?
Both sheets are great budget options, but your specific needs will point you to the right one. I think the best choice comes down to whether you want a complete kit or a simpler set with a great warranty.
CGK Unlimited Split King Sheets Set 7 Piece is right for you if…
- You want a true “set it and forget it” bundle with two fitted sheets and four pillowcases.
- Your mattress is extra thick and needs the full 16-inch deep pockets.
- You value the social proof of over 126,000 customer reviews.
SPRINGSPIRIT Split Top King Sheets Sets is right for you if…
- A strong, no-questions-asked lifetime guarantee is your top priority.
- You already have extra pillowcases and just need the core fitted and flat sheets.
- You prefer a slightly higher-rated product, even with a smaller number of reviews.
❌ Who Should Skip All of These?
If you’re looking for natural fibers like cotton, linen, or bamboo, you should skip these. Both sets are made from microfiber, which is a synthetic material. Also, if your mattress is deeper than 16 inches, you’ll need to look for specialty extra-deep pocket sheets.
For most budget buyers setting up a new split king bed, I recommend the CGK Unlimited 7-piece set. Getting two fitted sheets in the box is just too convenient and valuable to pass up at this price point.
Frequently Asked Questions
Which split king sheets are softer, CGK Unlimited or SPRINGSPIRIT?
Both are made from microfiber and feel very soft right out of the package. In my experience, the CGK Unlimited sheets have a slight edge in that “hotel luxury” softness they advertise, likely due to their double-brushed process. The SPRINGSPIRIT sheets are also soft and breathable, but the difference is minimal. For most people, softness won’t be the deciding factor here.
Do I really need two fitted sheets for a split king bed?
Yes, if you have a true adjustable split king base where each side moves independently, you absolutely need two separate fitted sheets. The CGK Unlimited set includes both, which is a major advantage. The SPRINGSPIRIT set uses a single fitted sheet with a split-head design, which works but can be less convenient when making the bed or if one side needs replacing.
Which brand has better deep pockets for a thick mattress?
The CGK Unlimited sheets win on pocket depth. They are designed to fit mattresses up to 16 inches deep, while the SPRINGSPIRIT sheets fit up to 15 inches. If your mattress is on the thicker side, the extra inch from CGK can make the difference between a secure fit and a sheet that pops off.
Is the SPRINGSPIRIT lifetime guarantee worth choosing over the CGK set?
It depends on your priorities. The lifetime guarantee is a strong point for SPRINGSPIRIT and offers great peace of mind. However, for the same price, the CGK Unlimited set gives you more physical product—two extra pillowcases and a second fitted sheet. For most budget buyers, getting the complete 7-piece kit provides more immediate value than a warranty you may never use.
Why does the CGK set have so many more reviews than the SPRINGSPIRIT set?
The CGK Unlimited ASIN (B07Z43QMTY) has been on Amazon for much longer and has accumulated over 126,000 reviews. The SPRINGSPIRIT set is a newer listing with about 681 reviews. The higher volume for CGK indicates it’s a proven, mass-market product, but the SPRINGSPIRIT set actually has a slightly higher average rating of 4.5 stars versus 4.4.
Can I use these sheets on a regular king bed?
No, you cannot. Both of these are specifically designed for a split king size, which is two separate 39″ x 80″ mattresses. A regular king mattress is one piece measuring 76″ x 80″. The fitted sheets from these sets will not fit or stay on a standard king mattress properly.
My Final Verdict
After comparing both sets, the CGK Unlimited 7-Piece Split King Sheets are the clear overall winner for budget buyers. It gives you everything you need in one box: two fitted sheets and four pillowcases for the same price as the simpler SPRINGSPIRIT set. The 16-inch deep pockets also offer a slight edge for thicker mattresses. The SPRINGSPIRIT set is a good runner-up if a lifetime guarantee is your absolute top priority over having a complete kit.
If you’re on the fence, ask yourself one question: do you want to buy sheets once and be done? If yes, get the CGK Unlimited set. You’ll appreciate having the extra fitted sheet and pillowcases from day one.
