The older set i use now for when kneeling on the concrete,
those were replaced last year as they were the same size as the previous years ones, i have enough to do the full awning floor with a set for spares, brilliant for the dogs to lie on or children to play on, but you really appreciate them when you are on a hard standing with out any footwear on :blink: one other advantage is that they can be hung on the washing line when washed to dry
try doing that with a ground sheet :S
