#1 in this guide, and the entry where the material field and the title actually agree: the Cannons UK 20mm Flatline is listed as Rubber, and the packing list backs that up with four 1m x 1m tiles, 20mm thick, in black. At £157.99 for 4 square metres the price works out at about £39.50 per square metre, so what you are paying for here is thickness and weight rather than coverage. The tiles are square, solid in pattern, and the listing says they improve sound by roughly 18 to 23 dB depending on construction.

The number that does not hold is the weight. The specification table gives Item Weight as 38 kg. The bullets in the same listing say each mat is 18.5 kg, and Included Components says "4 x 20mm mats" — four times 18.5 kg is 74 kg, almost double the spec figure. The per-tile number is the one that fits the rest of the description, where the tiles are said to be heavy enough to lay without adhesive. Two other fields read oddly for flooring as well: Product Care Instructions is given as "Hand Wash Only" and Special Features as "entrance_mat". Everything on this page comes from the Amazon listing as it stands, not from a mat we laid ourselves.

## Questions people ask

**How much floor does one pack cover?**

The listing states 4 square metres, supplied as "4 x 20mm mats" — four tiles measuring 1m x 1m each.

**How thick are the tiles?**

Item Thickness is listed as 20 millimetres, and both the title and the Item Type Name repeat 20mm.

**How much does the pack weigh?**

The specification field lists Item Weight as 38 kg, while the bullets say each mat is 18.5 kg. For four mats that would be 74 kg, so the two figures do not agree.

**Do Cannons UK 20mm Flatline tiles need gluing down?**

The bullets say each mat is 18.5kg "so you don't need adhesives to fix them".

**Is it actually rubber?**

As listed, yes — Material Type is given as Rubber, and the listing makes a point of saying no bad smell unlike cheaper alternatives, with binder sourced from Germany.

**Do the tiles come with finished edges?**

No. The bullets direct you to search separately for "Cannons UK Flatline 20mm Corners and Edges".
