A 38 × 15 m Commercial Inflatable Obstacle Course Project in Spain

A Large Inflatable Obstacle Course Designed for a Spanish Customer

QIQU manufactured a large custom inflatable obstacle course for Echevarrena Asesoramiento Artístico, S.L.U., a Spanish company based in Begíjar, Jaén, Spain.

The project measures 38 × 15 × 6 m (124.7 × 49.2 × 19.7 ft) and consists of six connected sections designed to create a continuous play experience.

The customer initially contacted QIQU after coming across photos of another inflatable attraction manufactured by us for a different customer in Spain. Recognizing the product and its construction quality, the customer approached our team to discuss a new project.

Rather than selecting a standard inflatable product, the customer wanted a large attraction with multiple activities, including climbing, obstacle challenges, interactive games, sliding and jumping areas.

The project required considerable design development before the final configuration was approved.

From an Initial Concept to a Fully Custom Design

The customer initially considered a different layout based on an earlier 3D design prepared by our design team.

However, as the project developed, the customer reconsidered the overall dimensions, activity areas and structural layout. The original concept was eventually replaced with a substantially revised design.

Several rounds of adjustments were made to accommodate the customer's requirements. Although we no longer have an exact count of the revisions, the project involved extensive communication between the customer and our design team.

The final design was completed on February 23, 2024. After reviewing the updated layout, the customer confirmed the final version on February 28.

The finished attraction included six main activity areas:

• Volcano-themed climbing challenge

• Inflatable obstacle section

• Large inflatable slide

• Two interactive game areas

• Jumping and bouncing area

Basketball hoops and a soccer goal were considered during the design stage but were later removed from the final configuration. The other interactive activities remained part of the project.

The customer wanted a varied attraction rather than a simple inflatable jumping castle. Each section was designed to contribute to the overall playing experience.

Six Connected Sections in One Large Inflatable Attraction

One of the main engineering considerations was how to connect the six sections into one complete attraction.

Each section was manufactured separately and connected using heavy-duty hook-and-loop fasteners and D-rings.

The connection arrangement and installation sequence were established during the design stage. The six sections were intended to be assembled in a fixed order according to the approved layout, rather than freely rearranged.

This approach allowed us to manufacture and inspect the individual sections before connecting them into the complete structure.

The final configuration measures:

• Overall length: 38 m (124.7 ft)

• Overall width: 15 m (49.2 ft)

• Overall height: 6 m (19.7 ft)

• Number of sections: 6

• Total blowers: 12

• Blower power: 1,100 W each

Each section was supplied with two dedicated blowers, with the blowers packed separately for transportation.

For a large inflatable obstacle course of this size, the connection points are particularly important. The design, material strength, reinforcement and sewing quality all contribute to the performance of the complete attraction.

0.55 mm Commercial PVC for Heavy-Duty Use

The customer specifically wanted the material and manufacturing workmanship to match an inflatable attraction they had previously seen from another QIQU project in Spain.

We used 0.55 mm commercial-grade PVC material from Sijia for this project.

For large inflatable attractions, material selection alone is not enough. The construction quality also depends on how different sections are sewn, reinforced and connected.

Large structures experience considerable stress during inflation and use. Poorly reinforced seams or insufficient attention to connection areas can lead to seam separation and other problems.

This is why we pay particular attention to:

• PVC material selection

• Sewing quality and reinforced seams

• High-stress areas and structural connections

• Hook-and-loop fastening and D-ring positions

• Blower placement and inflation arrangements

The six sections were manufactured according to the approved 3D design, with attention to their individual construction and final connection positions.

For this type of large commercial inflatable project, good structural planning must begin during the design stage, not after production has started.

Production, Inflation Testing and Quality Inspection

The final design was confirmed on February 28, 2024, and production was completed on March 29.

Before shipment, we carried out inflation tests on every section.

The inspection covered the complete inflatable structure, including individual sections, sewing areas, reinforced positions and the connections between modules.

We also inflated the sections and photographed the finished products before sending the pictures to the customer for confirmation.

On April 7, we shared additional inflation-test photos with the customer.

The main inspection steps included:

• Checking each section after inflation

• Inspecting sewing and reinforced areas

• Checking the connections between sections

• Confirming the overall appearance against the approved design

• Checking the blower configuration

The customer could review the actual inflated products before shipment rather than relying solely on the original 3D drawings.

Packaging and International Sea Freight to Spain

Production was completed in March, but the customer decided not to ship immediately in April because international freight costs were particularly high at that time.

After discussing the shipping options, the customer chose to wait for a more suitable shipping arrangement in May.

The shipment was handed over to the logistics process on May 4, 2024. It was received at the Yiwu warehouse on May 5 and transported to Guangzhou Port on May 8.

The shipment was initially expected to depart on May 13. However, a last-minute vessel space adjustment changed the planned sailing schedule.

The cargo eventually departed on May 20, with an estimated arrival date of June 13.

The vessel arrived on June 16, followed by customs inspection and clearance procedures.

The customer confirmed receiving the goods on July 3.

The transportation process took longer than initially expected. The vessel schedule adjustment, customs inspection and subsequent logistics arrangements were outside the factory's direct control.

Although the customer was unhappy with the shipping delays, the manufacturing and product quality were not the source of the complaint.

For international buyers planning a large inflatable project, it is important to consider not only manufacturing time but also freight rates, vessel availability, customs clearance and final delivery.

A Custom Project Built Around the Customer's Requirements

This project involved much more than manufacturing a large inflatable structure.

The customer had a clear idea of the attraction they wanted, but the design evolved considerably before the final version was approved.

Our team worked through those changes, developed the final 3D layout, manufactured the six sections and completed inflation testing before arranging international shipment.

For QIQU, the experience reinforced an important point about large commercial inflatable attractions: successful manufacturing starts with a well-developed design, suitable materials and careful attention to structural details.

If you are planning a large inflatable obstacle course, a multi-section inflatable attraction or a custom commercial inflatable project, our team can help develop the layout and manufacturing plan according to your available space and intended activities.
