These splat mats are wonderful! With easy wipe-down and precious style - these are a must in any home with children messing around! They are 48x48 and are perfect under a high chair as a catch-all mat, or even as a craft mat for playdough, painting, coloring, etc. Many of our customers use them as tablecloths too. They are one sided - so the back is simply the back of the oilcloth fabric. To clean them simply wipe down or hose down. We do not recommend washing these in a machine due to the nature of oilcloth fabric. These splat mats are our #1 selling children's item - you can't go wrong with one of these! *All mats have a red merrow stitch on the edges.
