They are soft and thin and you barely know they are under the sheets. They are waterproof and just plain perfect. They are not quilted so there isn't that weird feeling you get laying on quilted protectors. They are as soft as a sheet. I would highly recommend these. ### ⭐⭐⭐⭐⭐ Wonderful for 12-14” top mattresses/Split King. *by on Reviewed in the United States April 25, 2026* I have a 12 inch top mattress Split King, (measure your mattress) this mattress protector fits perfectly without strenuous effort to put on, has plenty of elasticized material for underneath the mattress to protect from coming off, I believe that you could comfortably go to a 14 inch top mattress but maybe no more than that I would say, for ease with placement. You can make that call from the photos provided. But I love it, finally found one that fits the bill in all ways, feels durable and not cheap. I’m very pleased with this purchase and definitely recommend it. ### ⭐⭐⭐⭐⭐ Good quality, works well as a mattress protector *by on Reviewed in the United States November 24, 2025* Am using these on all mattresses for the family - excellent quality, no noise, soft. Fits a deep mattress well and snug, does not readily come off the corners, a big plus! Stays good after washing too! ## Frequently Bought Together - Kingnex Waterproof Split California King Mattress Protector for Adjustable Bed 2 Cali Twin XL 36x84 Soft Noiseless Jersey Fitted Matress Cover with Deep Pocket - Bare Home Split California King Sheet Set - 1800 Ultra-Soft Microfiber Split California King Bed Sheets - Double Brushed - Deep Pockets - Easy Fit - 5 Piece Set - Bed Sheets (Split Cal King, Grey) - Sven & Son Platinum Adjustable Bed Base Frame + 14 inch Hybrid Spring Matt (Medium Soft), Lumbar Support, Head-Pillow-Tilt, Massage, Under-Bed Lights, USB - Split California King --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/329791822-kingnex-waterproof-split-cal-king-mattress-protector-for-adjustable-bed](https://www.desertcart.us/products/329791822-kingnex-waterproof-split-cal-king-mattress-protector-for-adjustable-bed) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-14*
