I'm 65 and can't afford to break an ankle or lose time away from aerobic activity waiting for a joint to heal. So I really wanted a tramp with a stabilizing handle. This one has one and it is very stable, does not wiggle. The frame is also very stable. When I first put it together, after stretching the skin on, the legs were not touching the floor evenly, however after jumping on it a bit, they all evened out. It was also important for me to have a hexagon shaped one in order to have more jumping space than a round one (more forgiving if you happen to jump out of bounds). However, most of the hexagon ones had no covering for the rim (bungees). This brand has a covering that is the same fabric as the skin of the trampoline so it is visually pleasing and it has elastic straps that hold the covering to the frame. And the covering prevents your foot from getting stuck in between the bungies and possibly twisting an ankle. Other brands had complaints that the covering flaked off, but not this brand - it is high quality. The jumping surface is smooth but not slippery and I can jump with bare feet and it is not rough at all. Great jumping surface. And as has been said before, for older people, you want bungee cords to preserve your joints, not springs. This has it all - all the features I wanted - safety and aesthetics and a great price! Plus it was easy to put together. I did the frame and my husband did the bungees with no problem. I think their bungee system is genius and it is easy to follow how to put together if you watch the video on the desertcart page where the item is listed. I've been jumping half an hour three times a week for the past two months and no problems. This is a very impressive and sturdy rebounder. FOLLOW_UP: It is now over 5 years later, Thanksgiving 2025, and my tramp is still alive and kicking! (minus one bungee). They don't make this version of the tramp anymore (the hexagonal one), so they are unable to provide me with replacement bungees for it, so I am not supposed to jump on it anymore, so here I am on the Sunny site, shopping for another Sunny tramp, because after all, 5 years was a good life... I did keep up with that routine of 3 days a week, sometimes more than half an hour per day, so I guess it served me well. Actually the pad is still in excellent condition, from what I can tell. It's just the bungees that are slowly going one by one. Review: 36 inch great for running...treadmill alternative. - This is a nice piece of kit. I opted to buy the 36 inch model (not the 40 inch) as I will be running on it mostly, not really using it like a high-fly trampoline. I love that it’s not foldable and is thus sturdy. It is one pice (once assembled) and has no jointed or folds to make noise or squeak. The assembly was only the four legs with the provided Allen key and it’s straightforward. I like that the legs are curved outward and are not straight and directly beneath the rebounder; I think these wider legs give the unit stability even if you bounce off-center. The bungees were already in place, no assembly. It’s quiet during use, no “”mattress box springs” type sound like the spring tension rebounders. And the bounce surface seems thick and it’s mesh and appears that it’ll last a long time. This was more than I wanted to spend, but is a middle priced rebounder with a high quality feel. Stable, heavy-duty, perfect tension for jogging in place to save my knees. I’m a seasoned runner and enjoy giving my knees a break by using this rebounder once a week…by running in place, I don’t need a home treadmill. For runners who want a home treadmill but having trouble justifying cost and space, this is a great alternative as you can just use your heart rate monitor and get in a "zone" workout in whatever zone you want and for whatever duration you want. Sure, you can't log those miles on this rebounder to impress your Strava followers, but it's really about heart rate over time, now isn't it. ;-). This is a quality purchase. ## Features - 【PROFESSIONAL GRADE QUALITY】Featuring robust steel construction for maximum endurance, resilient elastic bands, and a space-saving square design, this premium trampoline takes home fitness to the next level. - 【FUN FULL BODY EXERCISES】Jump into fitness with an exercise trampoline!

The trampoline was easy to assemble, but it was hard to unpack the hardware kit - I had to use tweezers to get the washers out of the plastic as the plastic had adhered to the washers during shipment. ## Frequently Bought Together - Sunny Health & Fitness Springless Mini Fitness Trampoline – Premium Adjustable Bungee-Style Indoor/Outdoor Exercise Rebounder for Quieter and Safer Workouts - HERITAGE STORE Organic Castor Oil - Glass Bottle - Nourishing Treatment for Hair and Skin - Eyelash Serum for Eyelashes, Brows, Castor Oil Packs - Cold Pressed, Hexane Free, Vegan 16oz - 4 Pcs Castor Oil Pack Wrap Organic Cotton for Liver Detox, Stomach, Belly, Neck, Breast & Entire Body, Reusable Pads Kit for Hot/Cold Compress with Adjustable Elastic Strap, Waterproof & Anti Oil Leak --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/523583829-square-shapped-indoor-and-outdoor-exercise-trampoline-sf-s021047](https://www.desertcart.jp/products/523583829-square-shapped-indoor-and-outdoor-exercise-trampoline-sf-s021047) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-06*
