Nothing matches every filter you picked.
A king is wide, a California king is long
A standard king is 76 by 80 inches, a California king 72 by 84: four inches narrower, four inches longer. The two are not interchangeable, so check the label on your mattress before you order the cover.
A king cover holds a lot of fabric, and the zipper runs the full length of three sides. A zipper whose end closes under a flap or a hook is the detail worth paying for on a bed this size.

Questions
Questions about king bed bug encasements
What does a king bed bug encasement cost at Bed Bug Blocker?
From $19.99 for the Protect-A-Bed BugLock Plus Mattress Encasement at the king size, at our latest update, and up to $104.99 across the 24 king covers on this page.
Will a king cover fit your pillow-top mattress?
Measure your king mattress from the bottom seam to the top of the pillow-top. The deepest king cover here is the Four Seasons Essentials Six-Sided Zippered Mattress Encasement, made for 9-24" deep mattresses.
Do you need a king box spring cover too?
If your king bed stands on a box spring, yes: it has more places to hide than the mattress. A king platform bed or slatted frame needs only the mattress cover.
