Wamkos Trampoline 12ft

Specifications – Wamkos 12 FT Round Trampoline

Looking for a solid mid-size backyard trampoline that balances safety, durability, and value? The Wamkos 12FT trampoline punches above its weight class in all three. With ASTM certification, a reinforced steel frame, and upgraded enclosure system, it’s built to handle family use with ease – whether it’s daily energy-burning jumps or weekend fun with friends.

Frame

The frame is the foundation of any trampoline, and Wamkos gets it right. Instead of using thinner or uncoated steel found on budget models, this one is made from 1.3mm thick, fully galvanized stainless steel, and it’s spray-coated to resist rust over time. That extra thickness and coating help reduce flex and vibration, especially when the trampoline is loaded near its 400 lb weight limit. Four W-shaped legs distribute impact across eight contact points for added balance on uneven ground. Best of all, the bolt-free socket assembly eliminates a major headache during setup and even makes disassembly easier if you need to move or store it.

Springs

Wamkos has gone with 72 heavy-duty galvanized springs, and they’re no ordinary springs—they’re three times thicker than those found in standard trampolines. This means more responsive bounce and better shock absorption for both light and heavy users. You’ll notice the difference immediately – jumping feels snappier and more controlled, not loose or laggy like on cheaper spring systems. Plus, they’re hot-dip galvanized for rust resistance, so you don’t have to worry about outdoor weather cutting their life short.

Mat

The jumping mat is constructed from premium polypropylene (PP) and features 8-line cross-stitching, which helps prevent fraying and tearing at stress points. What I especially appreciate is the anti-graze texture that reduces skin burn from slips or slides, especially during barefoot jumping. Mat elasticity is excellent for a 12-footer, giving enough lift for older kids and even adults to enjoy a real bounce without bottoming out.

Enclosure

Safety nets are often overlooked, but not here. Wamkos uses a high-density 110g UV-resistant net that holds its shape well and doesn’t sag over time. It attaches with elastic loops, not ropes, which means a tighter fit and less chance of gaps forming between the net and the mat. The no-gap design is a big plus—it keeps fingers and toes from slipping through spaces between the mat and springs. The zipper and buckle system also closes securely without being fiddly, so kids can easily open and close it on their own but still stay protected inside.

Enclosure Poles

The enclosure poles are curved outward, which serves two smart purposes: they create more usable interior jumping space and reduce the odds of a jumper slamming into the pole itself. Each pole is made of thick-walled steel tubing and is fully padded to soften any accidental impact. Unlike vertical pole designs that often flex inward under pressure, these maintain distance and stability thanks to their slight outward lean and better load distribution.

Included Accessories

• Sturdy, non-slip ladder
• Double-sided spring cover
• 4 U-shaped ground wind stakes
• Instruction manual

Key Review Takeaway

• Spacious & sturdy: Large enough for multiple jumpers (not that we encourage this), holds up well to over 350 lbs in real-use scenarios
• Kid-approved: Keeps children active and entertained
• Safe and secure: The net, zipper, and frame design are reassuring safety features
• Easy to assemble: Bolt-free design and clear instructions
• Requires two adults: Assembly is smoother and way faster with a second person around
