This review is long overdue. My son's birthday party was last summer and I wanted to have a small party in our backyard due to the pandemic. I found Eric per family recommendation for a jumper rental. I was pleasantly surprised that Cosmo also has rentals for tables, chairs and canopies. I needed all of those so I was happy to rent them all together from the same company. Eric was quick with providing a quote and communications via email. He asked for the dimensions of our backyard and found a jumper that would fit our turf area. On the setup date, he brought another jumper-slide combo just in case it would fit. It didn't but it was fine because we still had a jumper. He set up all the tables, chairs, canopy and jumper. He showed us how to inflate it, which was just a matter of plugging it in. He also wiped and sanitized all the items including the inside of the jumper. All the kids, especially my son enjoyed the jumper very much. We were able to keep the rentals through the weekend and got to enjoy them without additional cost. Eric came to break down everything the following Monday. He was quick and efficient. I would highly recommend Cosmo for any child's party. read more

Unfortunately this business does not rent out just their machines such as sno cone or cotton candy machines poor listing or information on the business and for yelp listing them when that all I searched for. read more

Prompt and professional service. Setup was quick and easy (which they did) Price was very reasonable. On time for drop off, which was extremely important, considering it was for a kids bday party. I only wish they would've communicated with me more after setup to get exact details of when they'd be back, also, before they left, after tear down. I wasn't able to tip them or thank them for their service. I had tacos and a tip for the workers, but they bounced immediately w/o word, I didn't even see them leave. Otherwise, extremely happy with service, id def hire them again. read more

Rented a bounce house w/ banner and generator for my daughter's birthday party in a park. Eric and team were super responsive throughout the process. Bounce house quality was better than expected and pricing was reasonable. Would use them again for future parties and highly recommend if you're looking for inflatable options. read more

We've rented jumper houses from Cosmo Jump twice now. Every time has been a smooth and great experience. You have to reserve through their website and they get back to you via email or phone rather quickly. Pricing is super affordable too. They confirm your delivery the date before your party or function and they're always on time for delivery and set up. Great customer service! Would definitely continue to rent from Cosmo Jump. They have tons of options for jump houses and games. They pick up and disassemble right on time as well. read more

Cosmo Jump was an excellent local business that provided an awesome experience for my sons 3rd Birthday. Eric the owner and operator was super friendly and very easy to schedule with. Highly recommend for any birthdays or family events. read more

Absolutely wonderful service. We had the worst experience with Bay Area Jump for my sons birthday so a few weeks later I decided to order from Cosmo to make it up to my son. His own jump house for the day. It was last minute and Eric was so accommodating. He even brought a bounce house with a hoop to make it extra cool. He was on time, and really friendly. I will never order from anywhere else. If you are looking for a bounce house/birthday party stuff.....don't waste your time anywhere else. Check my review out on Bay Area Jump. You'll see the hell I went thru. This was easy, affordable and pleasant. Eric came to pick up the bounce house and saw our son was still playing, so he's leaving it overnight. Pretty awesome. It's the simple things! Eric- if you read your reviews....thank you! It's refreshing to know people (businesses) like you, still exist in this crazy world. read more

Eric provided great service, responded promptly and made the drop-off & pickup scheduling real smooth. He made sure to wipe the jumper clean once it was up and the kids had a blast in the mini castle. read more

Rude! Called the number and the guy barked and hung up on me. Don't have a business number if you can't answer professionally!

Cosmo Jump and Eric are the best. They were a huge help to me when another vendor couldn't follow through for my event. They are courteous, responsive, kind, and punctual--all so important when planning hectic kids gatherings! So grateful for their local service for our community. read more

We rented a jumpy house from Cosmo Jump for my son's party this past weekend. Communication was great from the start. They were on time and set up was easy. The jumpy house was clean and in great shape. I will use Cosmo Jump again in the future. read more

Eric was super responsive and easy to work with. I planned a last minute birthday party for my son with social distancing being an important factor. I needed something outdoors where the children can take turns and not be in/on at the same time so I was on a hunt for a specific waterslide and though it wasn't listed on their website he was able to provide it. Eric came early to set up and picked up on time. Thank you for help making the party a huge success! read more

Great experience booking the 9 hole mini golf set. They were on time with set up and prompt with take down. All the guests loved it and kept asking where we got it. Nothing but positive things to say! read more

I contacted Cosmo jump for a jumper rental and Eric was so accommodating for our very last minute request. They have such a great selection of items, it was almost hard to pick! He confirmed quickly and let me know the afternoon before what time he would be coming to set everything up. On the day of set up, it all went up quickly, quality was great and they had everything wiped down before the kids got jumping inside. He was very friendly and responsive - we would definitely use again and highly recommend! read more

Great customer service, very responsive, on time and understanding. Competitive price to other jump houses. Will use again!

Amazing service! Highly recommend! I had Soto Bouncin House cancel on me 1 hour prior to my event and Cosmo jump arrived almost immediately and saved the day! Will definitely be using their services in the future read more

It was a joy to rent from Cosmo Jump, one of the easiest parts of organizing a recent birthday party. They were friendly, took care of the permit side of things as we were using the jumpy in San Carlos parks. They arrived when they said they would, then set everything up and even though we finished a bit early, they made sure to get there so we weren't hanging around. Their prices were reasonable too. I will go straight to Cosmo next time I need a party rental. read more

Awesome company and reasonable prices! I was worried that I wouldn't have a jumper for a holiday to entertain the kids. Other companies I used in the past were closed, but not Cosmo Jump! The kids played all day in the jumper and it was the highlight of the party. This company communicates promptly and has quality materials! read more

Eric provided excellent costumer service throughout our transaction. He showed up right in time in order to set up for my event and managed to wrap things up in a timely fashion. I'd definitely recommend Cosmo Jump! read more

Whomever runs this business is rude. I called for a quote thinking it was the business we've rented from frequently the past that was able to provide jumphouses on the same day we call. The man that answered the phone seemed really unprofessional. To top it off, I asked if we were in their database because we were trying to figure out if this was the place we usually rent jumphouses from. He replied that he wasn't at the office, which was understandable, then continued to ask which jumphouse we were interested in. I told him the standard jumphouse and he quoted somewhere around $180. I was like "ohhh, I thought they were previously &130?" Again, thinking this was NorCal Jump(couldn't recall the business name at the time of this call) Instead of being even slightly polite and saying "no, that's not our price. It's usually $180" he goes "nah that's not the price my houses go for. Goodluck" and hung up on me. Extremely rude and unprofessional, not like the other company at all. You'll find a better deal and less attitude elsewhere. read more

Eric is fantastic to work with. After reading reviews from several different party rental places, and requesting various quotes, I felt most confident in going with Cosmo Jump. It took Eric a little while to get back to me initially but that wasn't an issue as I had contacted him a few weeks before my kids' birthday party. He was the one business owner who got back to me regularly and took the time to answer my questions at length. He was also the most transparent. I'm not going to lie, his response to the one bad review is what sold me. I saw that should anything go wrong the day of my boys' birthday, Eric would work to make sure it got sorted out and that we weren't left hanging. Everything went smoothly thank goodness and a large part of that was thanks to Eric. This is a real family run business. Everyone at the party commented on how nice things were and how great it was to have seating and shade for everyone. My kids spent all day in the bounce house until it was time to take them down. Everything was super clean and put up and taken down quickly. Eric was punctual as well. We will be going with Cosmo Jump for any future events. We were so happy with the service that they provided. Thank you, Eric! read more

I had Cosmo Jump deliver a bounce house for my sons 2nd birthday. Coordinating everything was easy and my emails were always answered right away. The delivery was simple and so was pick up, very friendly and great customer service. I will definitely continue using cosmo jump for any future birthdays and highly recommend them to friends and family. Thanks again, my sons birthday was a hit and all the kids had a blast in the funhouse! read more

Cosmo Jump is great! They were referred to me by their competitor and I turned to be one happy customer! Eric answered emails and phone calls promptly, delivered the jumping house on time, it was clean, Eric is very professional and easy to deal with. Prices are very reasonable. I am very happy to have found Cosmo Jump and highly recommend these guys. When I need a jumping house again, I know who to call. Thank you, Eric! read more

One of the worst things someone can do is not show up for a child's birthday party when that child was super excited for a jumper. What a low blow. If I could, I'd rate Cosmo Jump a negative 10. They came to my house the day before to see if they could set up the jumper and the water slide- wasted 25 minutes of my time. They confirmed the waterslide and jumper would fit. They even made us move patio furniture around. Mind you it was super heavy. They guaranteed a 9am to 10 am delivery time the next day. We waited hours with a no show. My husband and I didn't leave the house to run errands for the party thinking they'd show up. They never called and ignored my phone calls and text. Very unprofessional. If you'd like to get stood up and have a very sad child on his/ her birthday than call Cosmo Jump. Reporting them to BBB. How could you do that to any child Cosmo Jump?!? read more

We are repeat customers! Just had a party last weekend complete with bouncer, game, table and chairs. Cosmo jump was so easy to work with and all items were a huge success at the party. Thanks! read more

Great service for our bouncy house rental for our kid's birthday party. No problems at all.

We still use this company for our jumpy houses...its usually just once or twice a year for birthday parties and special kiddy occasions. We love the service we get from them, and im always happy to help out small businesses when they deserve it. And this company definitely does! read more

Great service, very helpful. Eric was great when we wanted to add things on (lots of good stuff for parties, just ask him). We had a great event and would recommend! read more

Great service and really responsive by phone and email. My son loved the bounce house for his birthday. Drop off and pick up were on time.

I rented a jumper w/a slide for my sons Bday party this past weekend and was so happy with Eric. From the beginning he was very quick with responses and answered any questions I had. He was also very accommodating when I had to make changes. I called an hour before we originally planned to have the jumper picked up & asked if we could have it extended an extra hour and was no problem. He was on time for the delivery time so my son and my boyfriend had time to play before the party started. I also appreciated they cared about making sure everything was set up nice & clean before leaving it for us too (I've been to parties where they dropped off dirty jumpers and this was a relief). After reading many bad reviews for other jumper rental companies ,I was happy I came across Cosmo Jump and felt confident everything would run smoothly and it did. Definitely found my go to person for future parties. Thank you Eric for everything ! read more

Eric is super professional! He answered phone call/email and even called me before the event! Arrive on time, all the good things you can think of! I highly recommend him! read more

Working with Cosmo Jump was amazing. We had a park jumper birthday party planned for my very excited 5 year old. It was during the Northern California fires and the air quality was all over the place the week leading up to the party. Eric was incredibly flexible and patient and let me decide the day of the party if we would do the party outside so we could get the jumper depending on the current air quality (due to the unusual circumstances it was very much appreciated). Fortunately the air quality and weather cooperated and he was very timely on both ends of the delivery. He was friendly and even threw in a couple extras. The jumper itself was excellent and he had just the banner my daughter wanted. His sweet family was there to help with setup and takedown and I was happy to support a small local family business. This was a wonderful experience and I would recommend Cosmo Jump to anyone looking for a jumper. read more
