Features

  • Reinforced Packaging In order to deliver the package in good condition, we have made double-layer reinforcement for the package and carried out 24-hour air pressure test before shipment. Please refer to the instruction manual for setup, storage, maintenance and care.

  • Why are our PVC inflatables so tougher than any other? In the course of designing our rides, durability is the first obstacle we clear. Our commercial water slide is constructed from 0.45mm durable PVC material, certified by CE and ASTM safety standards.
  • Quality Goes a Long Way Here, we are constantly striving for quality. We don't cut corners when it comes to sewing. We strive to assemble the unit using double to quadruple stitching techniques, 4-5 stitches per inch. Our progressive workmanship makes it more durable and stronger than some advertised PVC inflatables, last for 3-5 years.
  • Edge Laminating ReinforcementAll high pressure areas are made of double-layer PVC with hot-welding technology for edge laminating reinforcement. Edge laminating width up to 2 inch. This method minimizes the amount of water that may seep into the inflatable.
  • Easy and Quick DrainageTwo drainage outlets on the bottom of the slides to fast draining the water that seep into the inflatable. And the drainage port at the front of the pool to easily drain the pool. Attention: Please close the two drains' velcro tightly before inflating. Thoroughly dry the unit before storage.
  • Beat The HeatCool the hot summer with the two water spray device on the top. And water hose was fixed on the side of the water slide. Easily to connect to your garden water pipes without complicated operations.

  • Works great!
Color: Purple
Was going to give it 1 star because we thought the blower wasn’t strong enough. We found the problem and fixed it. We didn’t make sure that all patches were securely patched in the correct places. The kids love it and are having fun in it as I’m currently typing. I can give another update in a week or 2. ... show more

  • Best purchase ever!
Color: Green
Tired of paying rental fees for water slides every summer, we decided to buy one for my boy's birthday party. BEST DECISION EVER! This slide is far better than any rental we've used. Setup was easy – it inflated quickly without any hassle. The drainage ports at the bottom can easily drain the water. The slide and splash pool were the instant hit of the party! Kids non-stop, shrieking with laughter for hours. Seeing their joy made it worth every penny.Great choice! ... show more
