The Silentnight Anti Allergy Double Duvet 4.5 Tog sits at number one in this guide, and it is the best-reviewed entry by a wide margin: 4.6 out of 5 from 25,304 ratings, at £16.99. It is a double-size summer duvet with hollowfibre filling and a microfibre cover, sold as machine washable and backed by a 5-year manufacturer's guarantee.

What the listing will not tell you is how much filling is in it. No weight appears anywhere on the page — not in grams of hollowfibre, not for the finished duvet. The 4.5 tog is filed in the spec table under 'Colour' and again under 'Style Name', while the warmth fields that do exist say only 'Lightweight' and 'Summer'. The anti-allergy approval is also named two different ways: the title says Allergy UK Approved, the first bullet says British Allergy Foundation. Everything on this page comes from the Amazon listing, not from any test we have run.

## Questions people ask

**How much filling does the Silentnight Anti Allergy Double Duvet contain?**

The listing gives no filling weight. It names hollowfibre as the filling material and microfibre for the cover, but states no figure in grams or kilograms for either the filling or the whole duvet.

**What does the 4.5 tog rating mean on this Silentnight duvet?**

The listing uses 4.5 tog in the title, and repeats it as both the Colour and the Style Name in the spec table. It lists Seasons as summer and Fabric Warmth Description as lightweight, but tog measures warmth, not weight, so the rating says nothing about how much filling is inside.

**Which allergy body approved the fibres?**

The title says the fibres are Allergy UK Approved; the first bullet says the Silentnight anti-allergy fibres are approved by the British Allergy Foundation. Both names appear in the same listing.

**Is the Silentnight Anti Allergy Double Duvet machine washable?**

Yes. The listing states it is machine washable and encased in a soft microfibre cover, which it says gives great recovery wash after wash.

**What guarantee comes with this duvet?**

The listing states a 5-year manufacturer's guarantee, and that the duvet is made in the UK.

**What does the anti-bacterial claim cover?**

The listing says the anti-allergy fibres are scientifically tested and proven to reduce or remove allergens, and are effective against 99.9% of bacteria.
