Cal King
SafeRest CloudGuard - Cal King Size Hybrid Mattress Protector & Pad (Extra Padded) - Waterproof Quilted Pillow Top Mattress Cover - Thick, Plush & Fitted Mattress Topper for Bed
4.4 (331 ratings — across all sizes of this protector)
California King owners usually bought the bed for how it feels, and a stack of pad plus protector undoes exactly that. CloudGuard puts both in one piece: a thickly quilted, cloud-soft surface across seven feet of mattress, with an ultra-thin water-resistant barrier inside the quilting and deep elasticized corners that keep the whole thing flat.

Three layers of thinking
1
Quilted pillow-top surface
A delicately padded surface that adds subtle plushness rather than bulk. Across a bed this large even quilting is what keeps the loft from migrating into ridges and hollows.
2
Barrier inside the quilting
The water-resistant layer sits beneath the plush face, tested to industry standards, guarding against fluids, sweat, allergens and dust without altering the silence or breathability of the bed.
3
Deep elasticized corners
Deep stretch corners grip the long California King profile and settle into a smooth uninterrupted fit. One layer means nothing can slide out of register with anything else.
The night test
Treat the first week as a trial of the mattress, not of the pad: softer surface, same airflow, no sound. Protection that improves the bed is the only kind people keep on it for years.
Care
Machine wash cold and tumble dry low in a load of its own, allowing a full cycle for the quilting to dry through. It is built to resist wear and repeated washing without losing shape. Full care guide →
