Builder's trays are a must for parents of small chidlren as they contain messy play. They offer so many options of what to do with them from play dough and painting to sensory gardens or water play (outside). This one is very sturdy and level. I bought some at B&Q that were slightly cheaper but made of much thinner plastic and had an uneven surface. I would recommend this tray. You will get good value for your money. I bought mine over a year ago and it is still like new.
