JumpSport 350 Pro Review (2027): Adjustable Tension, Planted Frame
Full research review of the JumpSport 350 Pro: adjustable EnduroLast cords, arched legs, capacity, and how it differs from the 250.
JumpSport 350 Pro Fitness Trampoline
Adjustable tension bungee model with arched legs and a larger mat than the 250.
- Bungee cords, adjustable tension (EnduroLast 4)
- Suspension
- 39 in
- Frame diameter
- About 32.5 in across
- Usable mat
Our verdict
The 350 Pro is the JumpSport for people the 250 does not fit: heavier users, athletic bouncers, and households sharing one trampoline across very different weights. Adjustable cord tension is a rare and genuinely useful feature, the 300 lb rating gives real headroom, and the arched legs remain the most planted feel in the class. Its limits are the 39 inch frame, which caps mat room, and a total cost with the bar accessory that approaches bellicon money.
What we like
- EnduroLast cords allow tension adjustment, unusual among bungee models
- Arched legs do not wobble or walk across the floor under hard bouncing
- Padded skirt covers the cords, which matters for bare feet near the edge
What to watch out for
- Premium pricing sits close to bellicon territory on sale days for bellicon
- 39 inch frame gives less usable mat than 44 to 48 inch rivals
- Heavier than budget trampolines, so daily closet storage is a chore
Who it is for
Heavier or stronger bouncers, and shared households that need one trampoline to suit two body weights.
Why adjustable tension matters
On a fixed bungee trampoline, a light user can feel underwhelmed and a heavy user can bottom out the mat. The 350 Pro lets you change cord configuration to shift that feel. Owners sharing the trampoline with a partner rate this as the reason to pay the premium over the 250, more than any frame difference.
Frame and legs
The arched leg design spreads load and resists the rocking that straight leg budget models show under hard bouncing. It does not fold, so the trampoline lives where it is used. The padded skirt over the cords is a small detail bare feet appreciate every session.
Ownership over time
JumpSport sells mats, cords, and accessories directly, and the model line has been around long enough for owner reports to cover multi year use. Cord life is measured in years, and the frame rarely features in complaints. The recurring gripes are price, assembly patience, and the bar being an extra.

FAQ
Questions, answered straight
Is the 350 Pro worth it over the 250?
Yes if you are over about 200 lb, bounce athletically, or share the trampoline. No if you are a lighter solo user; the 250 gives you most of the experience for less.
Does it fold for storage?
No. The arched legs are fixed. Plan a permanent spot, or look at the Cellerciser or BCAN folding designs.
