One folding leg on your table is made to lock with the table-top to stop the legs opening when you are transporting it. Gently open this locking leg first to set-up your table.
Each table top and legs are twice varnished to help to protect it.
To clean your table, please wipe it over with a slightly damp cloth (almost dry), then dry it before storing it away from moisture or direct sunlight.
To best care for your table, you should keep it in consistent, stable conditions to minimise the effects of temperature and moisture change. Plywood is a product that can respond to temperature and humidity variations by expanding and contracting and can delaminate if subjected to damp and wet conditions or extreme heat.
Do not store your folding picnic table in direct sunlight or in a damp or wet place.
