{"product_id":"waterproof-mattress-protector-california-king-size-zippered","title":"Waterproof Mattress Protector California King Size - Zippered","description":"\u003cp\u003eIn this review the waterproof mattress protector for California king mattresses is judged on fit, protection and ease of use. It is aimed at people who want a full encasement rather than a simple pad; the single biggest reason to buy is the six-sided, zippered design that seals the mattress completely to guard against spills, bed bugs and dust mites. The cover fits a 72 in by 84 in mattress with a 15 in deep pocket and uses a stretchable knitted polyester face with TPU backing to provide a comfortable sleeping surface while keeping liquids from reaching the mattress.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Encasement:\u003c\/strong\u003e The zippered cover secures around the mattress 360 degrees so the entire mattress is protected from bed bugs, dust mites and surface spills.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExact California King Fit:\u003c\/strong\u003e Sized to fit 72 in by 84 in mattresses with a 15 in deep pocket so it slips on mattresses with up to 15 in depth without bunching.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComfortable Surface:\u003c\/strong\u003e Stretchable knitted polyester fabric provides a soft, breathable feel that moves with the mattress rather than feeling like a noisy plastic sheet.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWaterproof Backing:\u003c\/strong\u003e High quality TPU backing on all sides resists leakage into the mattress to keep the interior dry from routine spills.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy Care:\u003c\/strong\u003e The washable design allows machine washing and tumble drying for simple maintenance and routine cleaning.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis encasement is best for homeowners and renters who need comprehensive mattress protection and want a cover that seals completely around a California king mattress.
