48 gym mat puzzle floor tiles. Each tile is 24" by 24". I have them in a 4 tiles by 12 tiles arrangement = 8ft by 24 ft.
They are each 0.79" thick and are great for weights and cardio. I also have all the spare edge pieces (image 3) so if you want to arrange them differently you should be able to come up with any arrangement.
I used these in my basement for my home gym. Selling because I am moving and won't have room for them.
Selling four boxes/48 pieces for $175, retail would be $480.
