Rank #1 in Best Gym Flooring 2026: 10 Mats Ranked by Thickness
Cannons UK Flatline 20mm Rubber Gym Tiles, 1m x 1m
Price and rating as shown on Amazon when we collected them. Both change.
#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.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I've used this in my garage gym, it's brilliant! Easy to cut with sharp knife, miles better than the foam rubbish you see readily available on Amazon. It's heavy enough to just lay down, I've had this in for over a year now, highly recommend.”
Verified purchase“I've bought 8 of these mats plus the edging strips over the last 10 months. They have transformed my home gym/shed. They don't move around, the grip is great and they are perfect for all round gym use. They arrived quickly and I could track the courier. Excellent service from Cannons.I am a big believer in buying decent stuff as it will last you for ages - and these mats are decent.”

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".
