Built to last in sturdy, pre-tested vinyl, these large and fun inflatable garden pools will provide fun for the family year after year.Using multiple L-beam chambers, and a huge, toughened ring to form the outer walls, the construction and design of the pool ensures it can support the weight of the water without deflating, and an in-built safety valve allows for easy and fast inflation and deflation.The standard size of the valve ensures it's compatible with most off-the-self electric or foot/hand pumps, to save you huffing and puffing. Once erected they will stay put for a long length of time.
