"Split king" refers to bedding designed for a king bed made from two Twin XL mattresses placed side by side. Because each side is its own mattress, the sheets are a little different.

• What’s included: Most split king sheet sets have two Twin XL fitted sheets, one king flat sheet, and two pillowcases.
• Why it’s helpful: Each fitted sheet stays on its own mattress, which works well with adjustable bases.
• Fit tips: Measure mattress depth and choose standard, deep, or extra-deep pockets as needed. Look for "split king" in the product title.
• Note: "Top split" (split head) sheets are different—those fit a single king mattress with a slit at the head.

Yellowing can happen over time and is often linked to everyday use rather than fabric defects. Common contributors include body oils, sweat, skincare or hair products, and even hard water minerals.

• Care tips that can help:

1. Pre-treat discolored areas with an enzyme or oxygen-based stain remover. Avoid chlorine bleach on microfiber or colored cotton.
2. Wash in warm water with a quality detergent. Don’t overload the washer so soils can rinse away.
3. Skip fabric softener on microfiber; it can reduce breathability.
4. Dry on low to medium heat and remove promptly.
5. Launder sheets weekly (or more often in hot weather), and consider mattress and pillow protectors.

Always follow the care label and test products on a small area first, since results can vary by fabric.

Split king sheets are popular for adjustable beds, but there are a few trade-offs to consider so you know what to expect.

• Center gap feel: You may notice the space where the two mattresses meet. A bed bridge or a shared topper can reduce this.
• More pieces: Two fitted sheets mean more items to launder and keep matched.
• Sheet separation: When each side moves independently, a shared flat sheet can pull unevenly. Deep pockets and optional sheet straps can help.
• Compatibility: Standard king sets won’t fit correctly—look for sets labeled specifically as split king.

These points vary by setup and preferences. Many shoppers find the flexibility outweighs the trade-offs, especially with the right accessories.

Think in pairs for a split king, then layer for comfort and movement:

1. Protectors: Place a mattress protector on each Twin XL mattress.
2. Fitted sheets: Add one Twin XL fitted sheet per side. Choose deep pockets if your mattress is tall or has a topper.
3. Flat sheet: Use one king flat sheet over both sides, or two Twin XL flats if you want independent coverage.
4. Blanket/duvet: A shared king comforter creates a unified feel; two lighter blankets let each person adjust warmth.
5. Pillows: Finish with pillowcases and any shams.

On adjustable bases, avoid tight tucks at the head so sheets can flex without pulling when you raise or lower the bed.

They’re made for different mattress setups, so picking the right type matters for fit.

• Split king: Two Twin XL mattresses side by side. Sheet sets usually include two Twin XL fitted sheets that run head-to-foot and one shared king flat sheet.
• Top split (split head): One king mattress with a slit only at the head section (commonly about 28–34 inches, depending on design). The foot stays connected, so the head can move independently.
• How to choose: If you have two separate mattresses, choose split king sheets. If you have a single mattress with a split head, choose top split sheets.

Check your mattress and base details before ordering; product titles on Walmart.com typically specify the exact style.
