Frequently Asked Questions

Why Should I buy the Bundle

Purchasing our trampoline bundle offers an unbeatable combination of fun, safety, and convenience, providing everything you need to enjoy your trampoline day and night. Here's why opting for the bundle is the smart choice:

Complete Set: The bundle includes the trampoline, an LED light kit, and a weather cover, ensuring you have all the essentials in one purchase. This means you won't have to spend time and money buying accessories separately.

Enhanced Experience: The LED light kit elevates your trampoline experience, allowing for nighttime use with a variety of color options and effects, controlled by a UHF remote. It's a game-changer that turns your trampoline into the neighborhood's hot spot, as our customer Nia discovered, receiving countless messages about the cool, color-changing lights.

Weather Protection: The weather cover is crafted from high-quality PVC with a central grid to drain water, protecting your trampoline against rain, snow, sunlight, and dirt. This prolongs the lifespan of your trampoline, ensuring it remains a family favorite for years to come.

Ease of Installation: Both the LED light system and the weather cover are designed for easy setup. The light kit's plug-and-play feature and the cover's straightforward assembly with strong pegs mean you can enjoy these enhancements without any hassle.

Value for Money: Considering the individual cost of these items, the bundle offers significant savings. With glowing reviews like Rich T.'s, who couldn't imagine a trampoline without the LED lights, it's clear that the added fun and functionality are well worth the investment.

This bundle is not just about buying a trampoline; it's about creating an environment where family and friends can enjoy endless fun, day and night, in any weather. The LED lights add a wow factor that can't be underestimated, transforming your backyard into a magical playground, while the cover ensures your trampoline stays protected against the elements. Together, they offer convenience, safety, and an enhanced jumping experience that makes the bundle an obvious choice for any trampoline buyer

Should I buy an anchor set for my above ground trampoline?

Yes! While these trampolines are very heavy, any strong winds can turn your trampoline mat into a sail and send it flying or rolling. These anchors are easy to install and will prevent your trampoline from being ruined in a strong windstorm.

What are the benefits of a round trampoline?

Round trampolines offer large jumping beds that are perfect for kids, teens and even adults. The 14 Foot Round trampoline actually has more jumping area than a 10 x14 Foot Rectangle trampoline – just ask the geometry expert in your family! The shape also allows users to easily identify the center of the trampoline for maximum jumping performance.

It snows where I live. Should I take it down in the winter?

We recommend you remove the mat, springs and pad unless it will be used during the winter. You can keep the frame up in the winter. If you have an enclosure, you can either disassemble the entire unit, or just take down the netting, and slide the foam pads up over the poles. Leave the metal poles on, and take down everything that is not metal. The main issue with keeping a trampoline up during the winter is the weight of the snow, not the cold. A heavy, wet snow piling up on your trampoline can easily exceed 1,000 lbs, exceeding the resting tear limit of your trampoline. If you choose to keep it up in the winter, it is crucial you sweep off the snow with a broom. DO NOT USE A SNOW SHOVEL! A snow shovel will rip right through your jump bed. If the trampoline is not being used, take it down to increase the life expectancy.

What can I do to care for my trampoline, so that it will last?

Our backyard trampolines are designed to handle the elements. However, there are steps you can take to extend the life of your trampoline. If you live in a northern climate where there is snow, we recommend you take it down in the winter (see below). Also, keep your trampoline clean. We recommend you wash the frame pad & jump bed a few times a year with a mild soap & water. After cleaning, spray the frame pad (spring cover), and the yellow vinyl outer ring of the jump bed with Formula 303®. Formula 303 is similar to Armor All®, with the exception that it contains a UV treatment. Keep your trampoline away from an open fire, and cover your trampoline during the 4th of July! One weakness ALL trampolines suffer from is hot ashes landing on the jump bed. This will burn a hole in your trampoline immediately.

Does the maximum weight limit indicate the jump performance?

Good question! This is commonly asked and the answer is a definite “NO!” Weight limits are set by manufacturers to indicate safety limits. Most manufacturers post a user weight limit. (Note, there should be only one jumper at a time on a trampoline for maximum safety.) In this instance, the user weight limit set by the manufacturer is 350 lbs – however the trampoline can handle an impressive 1100 lbs load in max weight testing. Most importantly, what influences performance are the trampoline design elements: sturdiness of the trampoline frame, the quality of the springs and the jump mat. We’ve tested all of the trampolines we sell and this trampoline offers an excellent jump experience.

Should I buy a Safety Enclosure with my in ground trampoline?

Safety is the top priority when answering this question. As falling from the trampoline to the ground is no longer an issue with an in ground, the primary concern is the clearance around the trampoline. If there are objects (trees, rocks, concrete pads, or natural drop offs) within 4 feet of the trampoline, we would strongly recommend a Safety Enclosure.

What are the benefits of in ground trampolines?

In ground trampolines offer four key benefits.
1) Safety issues with getting on, off or jumping without an enclosure no longer exist with an in ground trampoline.
2) The aesthetics or look of your backyard is much cleaner with an in ground trampoline.
3) Landscaping maintenance (mowing the lawn or weeding) is no longer required.
4) Water conservation as the area no longer needs to be watered.

Can I install the trampoline by myself?

Yes, many customers choose to install in ground trampoline themselves. The advantage of the Avyna design is that the soil that needs to be removed is about ⅓ of other in ground trampolines. That being said, many customers choose to have a local landscaping company install the trampoline for them, which may only take several hours by a professional.

Who Is the 15x15 Trampoline For?

  • Families Wanting Maximum Space: Ideal for multi-child households seeking a massive open canvas where everyone has room to jump.
  • Kids & Athletes Learning First Flips: Perfect for tumblers and young trick-seekers who need a wide, forgiving landing area.
  • Buyers Wanting the Largest Square Inground: The premier choice for homeowners with square lawn borders, patios, or pool decks.

Square vs. Round Mechanics

The square format offers distinct advantages over circular models. A round trampoline forces all perimeter springs to pull inward toward the center.

In contrast, a 15x15 square trampoline uses independent spring banks along its four straight rails. When a jumper lands off-center, only the local spring groups compress. This yields a higher, more energetic rebound near the edges.

Frequently Asked Questions

What size yard do I need for a 15x15 trampoline?

You need a clear, flat lawn area measuring at least 21 feet by 21 feet to account for the 3-foot clear safety clearance required on all sides.

How much jumping surface does the 15x15 square trampoline have?

The 15x15 square trampoline delivers a massive 225 square feet of usable jumping space.

How many springs does the 15x15 trampoline have?

The 15x15 Avyna Pro-Line MAX features 144 heavy-duty, double-galvanized 8.5-inch Power Springs™ that maintain uniform canvas tension across the entire square.

Is a square trampoline better for multiple jumpers than a round one?

Yes, a square trampoline is structurally better for multiple jumpers than a round model because its straight spring banks do not pull jumpers toward a central focal point.

How does the 15x15 square compare to the 12x18 rectangle in size and price?

The 15x15 square delivers 225 sq ft of jumping canvas, while the 12x18 rectangle provides 216 sq ft. The 15x15 offers a wider, more open layout for general play, while the 12x18 offers a longer runway for gymnastic tumbling. 

What warranty comes with the 15x15 trampoline frame and mat?

The 15x15 Avyna MAX comes with an authentic Lifetime Frame Warranty, a 10-year warranty on springs, and a 3-year warranty on both the jumping mat and safety padding.

Is the 15x15 trampoline available in an above-ground version?

The 15x15 is a flush-mount in-ground trampoline; there are no above-ground versions of the square trampoline at this time.
