Features

  • Big Size & Heavy Capacity21(L)x9(W)x12(H) ft, 6ft slide height. Holds 500 lbs total (200 lbs per user). Wet or dry all-season fun.
  • Family Splash PoolLarge pool: 9.5(L)x9(W) ft, 350 gal water capacity. Comfortably holds 2 adults + 3-5 kids (Age 3+) to enjoy a splashing pool party in the backyard or outdoor.
  • Why Our PVC Inflatables So Tougher Than Any Other? We start with durability. Made from 0.45mm commercial grade PVC, certified to CE and ASTM safety standards5X stronger than oxford or thin PVC water slide. Built to survive 3-5 years of family fun.
  • Commercial-Grade DurabilityMost cheap water slides crack, burst at the seams, or leak after one summer. Ours solves all two: (1) Double to quadruple stitching (4-5 stitches/inch) no seam bursting when kids jump and climb. (2) Hot-welded edge laminating (2 inches wide) at high-stress areas (slide, pool seams) no water leaking.
  • Ready in Minutes Smart & SimpleNo complicated setup. From box to backyard water park in under 5 minutes: Built-in top water sprayer keeps the slide cool all day; Multi-connector hose adapter fits any standard garden hose just connect and turn on the water;
  • Easy and Quick DrainageTwo bottom drains remove water that seeps inside the slide. Weve eliminated hard plastic drain plugs from the pool floor to create a completely smooth landing zone. Tip: Securely close drain Velcro before inflating, and dry thoroughly before storage.
  • Complete Package & Perfect DeliveryIncludes everything: water slide, white oxford storage bag, 950W blower, repair kit, anchor stakes, ropes, sandbags, hose adapter. Every unit passes a 24-hour air pressure test. Shipped in double-layer packaging arrives damage-free.

  • Great water slide
Color: Red
Easy to set up, great size for kids and adults, Fun for everyone even the littles, durable. We have set it up and taking it down multiple times and then left it down in the same spot for a week deflated and just tied down with anchors with no issue. Easy to clean as well.

  • Great Purchase
Color: Green
I ordered the "Green" version of this inflatable water slide and it has proven to be a great purchase. I have 3 children ages 8, 15, 16 and they truly enjoy spending time on this slide. It is large enough for all three to enjoy together. It is also easy to set up, just secure the slide to the blower (make sure to tie the straps to prevent air leakage), plug in, and turn on. It starts to inflate instantly. We have already used it multiple times and it has held up very well. Highly recommend! ... show more

  • Great product!
Color: Blue
So fun! Large enough for adults to use, and very kid friendly as well! The material feels sturdy, we have used it twice now and hopefully will be able to use it many more times!

  • Great slide for the price.
Color: Purple
The slide was a big hit with the kids. The slide appears well built, but the storage bag is cheaply made and was torn when I opened the box. The smaller kids had a little difficulty getting from the pool to the first step (slippery when wet) it use one more step closer to the pool. Extremely satisfied with the slide for the price. ... show more

  • Highly Recommend
Color: Green
Excellent quality—durable, commercial grade! Multiple linings in the pool area. We looked and looked for a water slide that was the “next step up” from the ones at Costco or Sam’s—-in height AND durability for our growing, rambunctious kids. This slide exceeded our expectations. It’s has been great for our kids and friends of all ages from 4 to 12 (and even adults). The negative side (storing it & temporarily killing your grass while in use) will be true of any inflatable you purchase. We think it was well worth it! ... show more

  • Slide had a hole right out of the box
Color: Red
Opened the box to set up the slide, found a hole where it wasn't sewed. Tried to contact the seller a couple times but no response.

  • Worth the $$$!
Color: Rainbow
So far, so great! Was time to upgrade our previous blow up slide since our kids keep growing! 4 and 6 year old, perfect size that they can easily grow into over the next few summers. This thing is huge and can easily accommodate adults! Only thing I wish I took into account is this is a 2 person job to take out / put away. ... show more

  • Be aware, open days ahead
Color: Green
Nice quality but when we opened the package it was moldy. Maybe a return that didn't get dried out properly? Idk but it was for a bday party the day we opened it so we scrubbed it and kept it. If we openeded it earlier I would have sent it back
