Rank #2 in Best Mattress Protector 2026: 8 Ranked by How Honest the Listing Is
Silentnight Waterproof Mattress Protector, Double
Price and rating as shown on Amazon when we collected them. Both change.
Silentnight's Waterproof Mattress Protector in the Double size, sold as a single pack, is the second entry in our guide. It costs £15.99 and holds 4.6 out of 5 from 8,589 ratings. It is a fitted protector with a 30cm skirt, a waterproof backing, a soft touch, rustle-free cover, and claims covering dust mites and hypoallergenic materials. Silentnight lists it as model 533942GE, machine washable, and 550 g.
What separates it from the entries either side of it is not the rating — it is that the listing's own numbers agree. The title says 1 Pack; Number of Items says 1; Unit Count says 1.0 count; Number of Packs says 1. The title says Double Bed and the Item Type Name field also says Double. The Fabric Type field gives one answer — Polyester — rather than the three different answers the number one entry gives for its surface. When the fields agree with each other, there is less to check before you buy. Everything on this page comes from the Amazon listing, not from testing we carried out ourselves.
