Split Top King Sheets 600 Thread Count vs California Design Den 600 Thread Count 100% Cotton Split King Sheet Set

Buy the Wholesale Beddings split-top set if you own an adjustable split-top king such as a Sleep Number and need a fitted sheet that flexes with each half. Its 32-inch top split, six corner pockets and center wings are built for that motion, and owners rate the fit highly. The California Design Den set is the better all-round cotton sheet: sateen weave, OEKO-TEX certified, machine wash and tumble dry, and far more owner ratings. Its fitted sheet is a standard deep-pocket split king, not a true split-top, so check your mattress type first.

  • Choose the Wholesale Beddings split-top set if your adjustable king has two independently moving halves and ordinary fitted sheets pull loose.
  • Choose the California Design Den set if you want a smooth sateen cotton sheet with easy machine care and a long track record of owner ratings.

Questions and answers

Which set fits a Sleep Number split king better?
The Wholesale Beddings set. Its fitted sheet has a 32-inch top split, six corner pockets and center wings so each half of an adjustable bed moves on its own. The California Design Den fitted sheet is a standard deep-pocket split king and is not built for split-top motion.
Which feels softer out of the box?
The California Design Den sateen is smoother and has a sheen from the start. The Wholesale Beddings cotton is plain-weave and some owners describe it as scratchy until it softens with repeated washing.
Which lasts longer?
Both use long-staple cotton at 600 thread count. California Design Den states its fabric is tested for shrinkage, pilling and fading and is OEKO-TEX certified, which gives more assurance on durability. Wholesale Beddings gives no such testing claims.
Is the California Design Den set worth stepping up to from a 400 or 500 thread count sheet?
Yes, if you want a denser, smoother sateen. The brand describes 600 thread count as a real step up in weight and sheen from 400 or 500, and the fabric softens further with washing.
Do both sets fit deep mattresses?
The Wholesale Beddings fitted sheet fits mattresses up to 18 inches deep. The California Design Den set fits up to 16 inches. Measure your mattress before choosing.
How do the pillowcases compare?
Both sets include pillowcases sized for a king bed. Wholesale Beddings lists two king pillowcases at 20 x 40 inches. California Design Den uses an open-end design without an envelope closure.
