FAQs - Jumping Jack Jumpers Information

Our delivery area includes all of San Francisco, The Peninsula and most parts of the East Bay.  If your location is in our delivery area, then, yes, the prices of our jumpers, concessions and games include delivery and setup by a knowledgeable and courteous driver who will ensure that your jumpers, concessions and/or games are clean and in good working condition before your event starts and return to take it down afterwards.  Normal set-up time is about 10 - 25 minutes and we’ll also need 10 - 25 minutes for take down.  We can make special accommodations for certain areas outside of our delivery zone but, will most likely require an additional delivery charge.  Please call if your location falls outside our delivery zone.

The safest surface for setup is a level grassy area.  However, we can also set up on concrete, asphalt or dirt surfaces.  A very slight slope is normally not a problem, however, the flatter the surface the better.  Please specify the surface type when ordering so we can bring the appropriate anchors for set up.  Under no circumstances can we set up where we think the inflatable will be a safety risk to any person or our inflatable.

Yes, if you have a two car width driveway, most likely a jumper will fit.  The jumper can also accommodate a slight slope without deterring from the full enjoyment of the jumper.

Yes, but you will need to contact the park or you city’s park and recreation’s department to get a permit.  Some city parks require a permit fee and some don’t allow jumpers at all.  You will most likely need to supply your own power source or rent a generator from us since most parks don’t provide electricity.  A $20 park fee is required for all parks and we require a $50 deposit.

As a general guide line:


  • Ages 2 to 8…… 8 to 10 children
  • Ages 9 to 12….. 6 or 7 children
  • Ages 13 to 16…. 4 to 6 children

Please keep in mind that only compatible sized children can play in the jumper at the same time, REGARDLESS of age. Different sized children must not be mixed. The older and larger the occupants are, the greater the risk of overcrowding and injury. The above is a guideline only. Please use common sense when using a jumper. As with any activity involving small children, there should always be an adult supervisor present.

We will call you that morning to discuss rain concerns.  In most cases, you can still use the jumper if it rains.  There is no charge to you for a cancelled reservation due to the weather.

The sizes of our jumpers are listed in their respective descriptions on our website. If your area can accommodate the jumper plus 2 feet on all sides, the space should be adequate (i.e. a 13’ wide by 13’ long jumper will require a space 17’ wide by 17’ long.) Most jumpers require at least 14 feet of overhead clearance. If you are not sure if your space is adequate, please don’t hesitate to call us and ask.


You can cancel your reservation for any reason up to 7 days prior to the date of the event without a penalty. If you decide to cancel less than 7 days from the date of your event, you will lose your $20 deposit. The only exception to this policy is for forecasted rain.

Yes, we can provide our insurance information upon your request.

Yes. However, some of our larger units cannot be maneuvered safely up and down stairs. A charge of $2.00 per stair will apply for all jumpers, and we must be notified of the number of stairs at the time that the order is placed. If the stairs are too narrow, too steep, or otherwise unsafe for delivery, we reserve the right to refuse delivery to that location. We will do everything we can, within reason to deliver the jumper.
