12′ Capital In-Ground Trampoline (Rectangle) – In Ground Rectangle Trampoline
Engineered for performance and designed to blend beautifully into your backyard, the 12′ Capital in ground rectangle trampoline delivers a smooth, powerful bounce and a sleek, low-profile look. This premium trampoline is installed flush with the ground, making it a safer, more visually appealing option for families who want a high-end solution for outdoor fun and fitness.
The rectangular shape provides a longer, more controlled bounce zone—ideal for gymnasts, tumblers, and jumpers who want consistency and room to move. Unlike round trampolines that pull jumpers toward the center, this in ground rectangle trampoline offers a more even rebound across the surface, making it perfect for routines, training, or just active play.
Built with a heavy-duty galvanized steel frame and reinforced jump mat, this trampoline is made to endure years of use. The high-tension springs offer maximum lift and responsiveness, while the unique airflow system underneath the mat ensures a quieter, smoother bounce than typical in-ground models. No loud thuds or resistance—just a clean and enjoyable jumping experience.
What truly sets this trampoline apart is its integrated retaining wall system, which reinforces the structure and keeps surrounding soil in place. This creates a safer and more durable in-ground setup that requires minimal maintenance. With no ladder needed and reduced fall height, this trampoline is a favorite among safety-conscious parents and active families alike.
The Capital 12′ in ground rectangle trampoline is more than just backyard equipment—it’s a performance-driven play system that brings excitement, fitness, and clean design together. Whether you’re a serious athlete or just love to bounce, this trampoline checks every box.

Frequently Asked Questions
Q: How To Assemble a Trampoline?
A: Assembling a trampoline typically involves connecting the frame, attaching the jumping mat to the springs or rods, and securing the safety net (if included). Each manufacturer provides specific step-by-step instructions, so it’s important to follow the included manual carefully. For Springfree trampolines or in-ground models like Capital, the process may be more involved due to the unique no-spring design or the need for ground preparation. Two adults are usually recommended for a smooth setup. We also offer referrals to professional assembly services if you’d prefer expert help.
Q: Is Assembly Included in My Order?
A: No, assembly is not included with your trampoline purchase. Trampoline installation is a separate service and must be arranged independently. At Kids World Play Systems, we can connect you with local professional installers to ensure safe and correct setup for your specific trampoline model.
Q: How to Measure a Trampoline?
A: To measure a round trampoline, measure straight across the center of the frame from outer edge to outer edge. For oval or rectangular trampolines, measure the longest side and then the shortest side across the frame. Always measure from the outer edges of the frame, not the mat or jumping surface. Accurate measurements help ensure you purchase the correct size replacement parts, enclosures, or accessories.
Q: How To Disassemble a Trampoline?
A: Disassembling a trampoline involves reversing the assembly process: removing the safety net, detaching the mat from the springs or rods, and breaking down the frame into its original components. It’s best to keep hardware and parts organized during disassembly for easier reassembly later. If the trampoline is anchored or built in-ground, additional tools and labor may be required.
Q. Are Trampolines Safe?
A: Yes, trampolines are safe when installed properly and used with a safety enclosure net. All trampolines sold by Kids World Play Systems meet or exceed industry safety standards, and we strongly recommend ordering a trampoline with a full net enclosure to prevent falls and injuries. Choosing models with flexible rod systems (like Springfree) or flush-to-ground designs (like Capital in-ground trampolines) further enhances safety for kids and families.

Customer Reviews
Can’t recommend this place enough if you’re in the market for a swing set. We stopped in a few weeks ago looking for a swing set for our son and were fully expecting to get the “supply chain delay” talk from them, but that wasn’t the case! They had last year’s floor models for sale at a deep discount and nothing really was wrong with them aside from needing a new coat of stain. They were super helpful educating us on the different models and features given our price point, all while our 2 year old ran around testing out every set. We ended up going with a floor model of the Panda, and they came out and delivered/installed it yesterday- a little over 2 weeks from ordering. Installation was quick and professional, and I feel like the set is safely constructed for my son to play. We fully expected to pay a premium and not get a set until July/August due to supply issues, but we ended up getting a great deal from a local business with free installation within 2 weeks of ordering!
I highly recommend! Great customer service! Michael did a great job helping my family choose a play system. He even sent aerial view with dimensions so that we could lay out our Playground Grass by ForeverLawn. Alex and Ray installed the play set. They communicated with me throughout, worked hard, and did a fantastic job! That day my kids got off the school bus and played until dark. The neighborhood kids all came over to play! Just awesome!
I was in search of a new trampoline for my son. After searching for a few weeks I walked into Kids World in Heartville. Tyler was very knowledgeable on all things trampoline! He was able to provide me guidance on exactly what I was looking for and went above and beyond to provide amazing customer service to me. The delivery was quick and installment went smooth once I received my product. I will be back and asking for Tyler again this spring when looking for a playground set!!
