We bought this several months ago in preparation for our little boy's birthday party. We had about 10 kids between the ages of 3 and 6. Each kid had a great time, the sides were sturdy netting, the stitching was strong and the flaps to enter were easy to maneuver. We are very happy with this purchase. The only issue I encountered is the storage bag it comes with is quite small. I would have to be a magician to roll it up that small, so we ended up using a large pillowcase and wrapping a tie around the top. Problem solved!

My grandchildren could not wait for the Magic Castle to come. When it did we decided to let them inflate it. Within 4 minutes they had it opened and inflated. That includes putting the carpet under it. The bounce house was everything advertised and more. Now all their friends come over and take turns on it. Its almost better then the pool. Thank you very much.

The Blast Zone Magic Castle Ultra 12 Bounce Castle is AWESOME! It is enormous, but still fits in our basement for cooler days (make sure you measure your space). Our 3-year-old and 1-year-old both love it! Our older niece and nephews love it too (they range in age from 7-13). We have used it 1-2 times per day for the past week since we bought it. The quality is very good and the bounce floor is very bouncy! We cannot wait to use it for our upcoming party (and not have to pay the same price it cost to buy it for a rental fee). Definitely worth the money!!!

Our 2 year old loves this bounce house. It was a gift for his birthday and he couldn't wait to use it. It is well made, great quality, better than other home bounce houses we have used in the past. It is a huge bounce surface and very easy to set up and take down. It's great for multiple kids using it at once. We highly recommend this bounce house!

This has been the best decision we have made as far as toys for our kids go. Our kids wear themselves out in this thing. They love it! Easy to set up. Only takes a few minutes. The neighborhood kids also love to run over and play. It's been great!

Got this to replace electronics at our house (so tired of my kids wanting to stay inside to watch movies or play video games, now they have some motivation to get outside and play). This is a fun bounce house. It is just right for my 4 kids ages 1yr to 8. They have spent hours outside playing all kind of games inside of it. It is so easy to put up and take down. I think my kids like it because it is different than a trampoline. My one year old was on it with my other kids and even though they were jumping, it didn't send him flying. They all had a great time. It is really a great quality product that I hope we can use for years to come!!!

My wife and I were at toy r us and we saw a bounce house on sale. I had seen this same one at our friends kids parties and thought there must be something better out there. I have a 3 year old, 1 year old, and baby due in 2 weeks, i figured it would make sense to get something of better quality thats gonna last. This thing is beasty, we already had a water slide one we purchased from kohls and you can clearly see the quality differences. Its a great product and kids love it, no complaints, im a real person and this is a real ass review. Who would say ass in a review just to prove im real.

My twin granddaughters age 2 years, and their big sister who's 6 years old, have been having a blast in their own bounce castle and they are the most popular kids in the neighborhood now! We love it! And Grandpa is their hero for giving it to them! & I love that!

We found it! We decided on the Magic Castle Ultra 12 and couldn't be happier with our purchase. The bounce house is Xtra Large and can accomodate up to 6 kids. The corners are tough and can take some rough play. We are pleasantly surprised of the bounce floor commercial quality and the friendly customer service we received when placing the order. Would definitely recommend if you are looking for a quality product your kids will enjoy for many years.

We ordered this for our kids' birthday parties which take place in the summertime. It was a great way to occupy a bunch of boys at a party. We've only used it twice so far so we can't really comment on the long-term durability. However, the size of this unit is great and the customer service was great too. We highly recommend this!

    Hi Tara,

    The Big Ol Bouncer is more popular, but other than the Magic Castle Ultra being taller and having a larger entry slide, the units are very similar; It's simply a matter of preference.

    All prices are in USD.

    Dear Sunny,

    No, this inflatable is not designed for commercial use such as rentals. It is designed for at-home uses including backyard or indoor use.

    The materials used to make this inflatable are not tested for commercial use and this inflatable also cannot be insured, making it illegal to rent out in most municipalities.

    I hope that helps!

    Hi Lynn,

    The total weight limits are 100 lbs per user, 600 lbs total.

    For further detailed specifications, please see:

    Blast Zone Support

    Dear Regina,

    The interior dimensions for the bounce floor are going to be very close to the Big Ol' Bouncer.

    The Magic Castle Ultra 12 has an interior bounce dimension of 118" x 117" while the interior bounce floor of the Big Ol' Bouncer measures in at approximately 119" x 115".

    I hope that helps!

    Hi Mandy,

    All inflatables must be set up on a soft surface, for both the safety of the players and protection of the inflatable form chafing and wearing. Provided the inflatable is anchored (usually with optional sand bags,) thick carpet is typically acceptable.

    Hi Sidonie,

    The top is not covered. None of our home use inflatables come with a roof covering in order to adhere to safety standards.

    Blast Zone Support

    Hi Abby,

    There is no difference between bounce surfaces. All home-use inflatables feature the same commercial grade vinyl in the bounce floor, so jumping experiences should be about the same.

    If you are specifically concerned with how high players will be able to jump, I would recommend viewing the item video here:

    This video shows the inflatable in action! I hope this helps.

    Hi Henri,

    The outside dimensions are approximately 146 x 146 x 108 inches, or approximately 12 x 14.5 x 8.5 feet tall, and the inside bouncing area is approximately 118 x 117 inches which is about 9.75 x 9.75 feet.

    Hi Sue,

    If the weather turns and starts raining while you are using your inflatable, discontinue use, turn off the blower, and put the inflatable away or bring it indoors.

    Hi Felicia,

    How It Works

    • What To Expect From Your Inflatable

      Blast Zone Inflatables use a constant flow of air, fed from the included blower. As air is pumped in, some escapes through the seams in the material. This creates a stronger inflatable with ideal air pressure, so your Bouncer or Water Park supports as much playing as your kids want to do. Escaping air is all a part of the process.

    • You Just Need a Garden Hose

      Blast Zone Inflatable Water Parks and Slides include a sprayer system that attaches to a garden hose, keeping the slides just slippery enough to slide. A Flow restrictor reduces water use. You can also adjust the flow yourself by adjusting the spigot. The sprayers only require a minimal amount of water to maintain flow on the slides, and Splash Areas have water outlets to keep water levels no more than 6" for safety.

    • Fast, Frustration-Free Setup

      Blast Zone inflatables are up and ready for play in a matter of minutes - with most taking less than 2 minutes to inflate. To set up your bouncer or water park, simply unroll it, hook the inflation tube to the blower, stake it down and turn the blower on. To take your inflatable down, just turn off the motor and it deflates on its own. Units roll up to the size of a medium to large sleeping bag and can be stored in the supplied storage case.

    • Durable, Safe Products

      Blast Zone takes pride in manufacturing the highest quality inflatables in the industry. Our home inflatables use commercial grade vinyl on all the bounce and slide surfaces. In addition, they are assembled with up to quadruple heavy duty stitching. We take your children's safety very seriously. By providing fully enclosed bouncers with safety netting and climbing surfaces with plenty of foot holes and safety handles, feel confident that your children will enjoy safe and fun play.

    • The Blast Zone Difference - Our Promise

      Blast Zone promises to provide stellar customer service. We back all our products with an industry leading warranty. Choose Blast Zone when you want an inflatable that is durable, safe, and designed for fun.
