OMG! Those are some thick mats! Mind sharing what company you used, and how much they cost?
I used Cannons UK
. The mats were £18.50 (ex. VAT) each. I checked out a few companies and ended up on eBay where I found these. Then I googled the brand and found them slightly cheaper on the manufacturer's website.
Next up (hopefully arriving tomorrow): a big section of tarpaulin to either cover the mat directly or to construct a temporary roof while this wonderful English weather persists.
