Eight metres square is a lot of deck. Four metres long, two wide, and rated for eight adults, so this isn't a floaty you take turns on. The whole family and the dog fit at once.
The mesh centre is the bit people don't expect. It lets water through and air past, so you sit half in the water and stay cool instead of frying on hot vinyl. On a 35 degree day that's the difference between using it and getting off it.
Drop-stitch double wall fabric at 4 to 5 PSI is what makes it firm. There are 16 grab handles and 6 D-rings on it, so you can climb on, tow it, anchor it, or tie it alongside the boat. Pump, repair kit and carry bag are all in the box.
