6-Pack Interlocking EVA Foam Floor Mats

Are there 6 of 24x24x.375 matts in this purchase? OR do the 6 matts equal 24x24 when put together?

Hey there, we can confirm that 1 unit = 6 mats that combine to 24 x 24 square feet of coverage.

I’m unclear how the two straight edge pieces work. Can multiple sets be combined to cover arbitrarily large areas?

Yes, that’s it exactly. Then you use the straight edge pieces to add a nice clean edge to the outer rim.

Are all the light colored ones gone?

All we have are the black ones at the moment. Sorry.

Gray ones are available on Amazon for $4 more with Prime shipping.
