Utopia Bedding Zippered Mattress Encasement California King — 6-Sided Waterproof, Bed-Bug & Dust-Mite Proof

Protect your California King mattress against spills, allergens and insects with a snug, six-sided encasement that fits mattresses up to 15 inches deep. The protector combines a quiet, knitted polyester surface with a secure wrap-around zipper and a waterproof inner layer so you get full coverage without the noisy crinkle of some alternatives. Easy machine care and a stretch design make installation and maintenance straightforward.

How does the zippered encasement keep my mattress protected?

The full-wrap zipper seals all six sides of the mattress, preventing liquids, bed bugs and dust mites from reaching the interior. The closure is designed for a close fit so the cover stays in place through normal movement and bed-making.

• 360° coverage fully encloses mattress sides and bottom.
• Durable wrap-around zipper for a tight, tamper-resistant seal.
• Waterproof inner layer blocks spills, sweat and stains.

Will this protector feel loud or change mattress comfort?

The outer surface is a soft, knitted polyester that avoids the crinkly noise of vinyl or some plastic-backed protectors. It lays flat and moves quietly with the sheet beneath for minimal change to the feel of your mattress.

• Non-crinkling fabric for quiet sleep.
• Soft, smooth knit preserves mattress feel.
• Stretch fabric conforms to the mattress for a neat finish.

Is it easy to put on, remove and clean?

The protector slips on like a fitted sack thanks to its stretch panel and generous depth allowance, then secures with the zipper. When it needs cleaning, toss it into a washing machine and tumble dry on low—no special treatments required.

• Stretches to fit up to 15-inch deep mattresses.
• Simple installation—see Utopia’s installation video for guidance.
• Machine washable and tumble dry on low for routine care.

Will this product fit my California King mattress dimensions?
