This is the number one best seller in Amazon's own mattress topper category, and the only topper here from a brand most UK buyers already know. Ten centimetres of Fibadown fibres, a box-stitched edge to stop the filling sliding, elasticated straps and a 135x190cm double fit, for £39.99.

It is sixth because of one number in its own table: 3.3kg. That is less filling than the MightySoft and the Jennifer at two thirds of the price, and less than half the memory foam toppers at the top. What Silentnight sells here is the brand name and the box-stitched construction, which holds the filling in place better than the cheapest toppers do.

## Questions people ask

**Why is it sixth when it is the best seller?**

Because of its own spec table: 3.3kg of filling is less than the MightySoft and Jennifer carry for £26.99. It is well made, but you are paying for the brand.

**What are Fibadown fibres?**

Silentnight’s name for a down-like synthetic microfibre filling, sold with a quilted cover and hypoallergenic.

**Does the box stitching matter?**

Yes. Box-stitched edges and internal walls stop the fibre from drifting to one end, which is the failure mode of cheap quilted toppers.

**Can I wash it in a machine?**

Yes, the listing states it is machine washable.

**Will it fit a standard double?**

It is sized at 135x190cm, which is a UK double, and uses elasticated straps to hold the corners.

**How many ratings does it have?**

5,620 at the time of collection, averaging 4.4 stars, with 70 per cent five-star and 5 per cent one-star.
