GIBBON makes balance training approachable, from a $99.99 tree-mounted slackline kit to indoor SlackBoards that need no anchors at all. Build quality, free training content and a two-year warranty make it easy to recommend, as long as you have the floor space and keep the wooden boards out of the weather.

Balance is one of the easiest fitness qualities to neglect and one of the most useful to keep. It underpins everything from sport to simply staying steady on stairs. GIBBON has built a whole category around training it in an enjoyable way, starting with the slackline: a flat strip of webbing tensioned between two anchors that you walk, bounce and balance on.
The company has since moved well beyond tree-mounted lines. Its wooden SlackBoards put a short, low line inside a frame that sits on your living room floor, and its SlackRack turns the concept into a freestanding fitness station. We looked at the full lineup, the pricing and the policies to help you pick the right entry point.
The company behind the lines
GIBBON was founded in Germany in 2007 by Robert Käding, who still leads the company as founder and CEO. The goal from the start was to make slacklining easier to set up. A notable chapter in the brand story came through Caroline Käding, a physical therapist who brought the SlackBoard into a clinical setting and now leads GIBBON's Medical SlackLine Concept. In 2026 the brand describes Solana Beach, California as a new home base for GIBBON North America.
That clinical thread matters. It explains why the indoor products are designed to be low to the ground and forgiving, and why the brand invests in free training content rather than leaving buyers to figure it out.
Three ways to train balance with GIBBON
SlackBoards (indoor, no anchors)
The SlackBoard is a wooden frame, about 42 inches long, 11 inches wide and 5.5 inches high, that holds a short line just above the floor. It weighs 7.5 lb and is rated to 400 lb. The original single-line board lists at $199.99. The SlackBoard Plus, at $229.99, arrives with two lines installed and can be converted to a single line, which lets beginners start on a more stable setup and progress to a harder one.
Slackline kits (outdoor, between trees)
The ClassicLine 2-inch Set ($99.99) uses polyester webbing with a 41-foot main line and a separate 8-foot ratchet strap. It includes a ratchet with a safety lock, a RatPad ratchet cover and two TreeWear pads to protect bark. An XL version is $129.99. For narrower, more technical lines, the BananaLama 1.5-inch Set is $109.99 and the BananaLama XL is $184.99. GIBBON also makes FunLine for beginners and JibLine and SurferLine models for tricks.
SlackRack (freestanding fitness station)
The SlackRack Fitness ($529.99) is a freestanding frame that configures to roughly 7 or 10 feet long and needs no trees. It comes with handgrips, a stretch band, a workout poster and rubber feet, and suits dedicated home gyms, studios or large playrooms.

Where to start
- Apartment or small home: SlackBoard Plus. The two-line mode gives a gentler learning curve, and it slides under a sofa or against a wall when you are done.
- Yard with two sturdy trees: ClassicLine 2-inch Set. The wider webbing is more stable for first-timers, and the tree pads are included.
- Mixed-ability family: SlackBoard Plus, since kids and adults can switch between two-line and single-line setups.
- Home gym or studio: SlackRack Fitness, if you have the floor length to spare.
Whichever you choose, the free GIBBON Balance App is worth downloading. It has guided programs and challenges, with the brand advertising more than 100 training videos and no required subscription. A Starter Bundle of extras lists at $49.98 and was on sale for $34.99 when we checked.
Pricing, warranty and returns
Regular prices run from $99.99 for a basic outdoor kit to $529.99 for the SlackRack, with SlackBoards in between. GIBBON runs frequent promotions; during our research the US store had up to 40% off SlackBoards, bundles and accessories, with a SlackBoard Plus variant reduced to $160.99. HSA and FSA payment is accepted.
Products carry a two-year warranty, and the brand offers a 30-day money-back guarantee. The US store advertises free shipping and was running an extended holiday returns window through January 31.
Two care points to keep in mind: the wooden boards should be protected from moisture and prolonged sunlight, and outdoor lines should be taken down rather than left tensioned on trees indefinitely.
Who will get the most out of it
GIBBON suits families looking for active play that is not screen-based, athletes who want to train ankle stability and focus, and adults interested in balance work as they age. The indoor boards are a good match for people who want to practice a few minutes at a time, for example while waiting for the kettle or during work breaks.
It is less suited to anyone short on floor space, and buyers who want a broad strength or cardio setup should look at it as a complement rather than a main piece of equipment. For a calmer mobility routine, a yoga setup from Everyday Yoga or a folding Pilates reformer may be a better fit.
Getting real value from balance training
Balance gear tends to be used enthusiastically for a week and then forgotten, so a little structure helps. In our research, the households that stick with it treat the board like a toothbrush rather than a workout: a few minutes most days, in a spot where it is always visible.
- Start with stance, not steps. Spend the first sessions simply standing on the line with soft knees and eyes on a fixed point ahead.
- Add movement gradually. Once standing feels calm, try weight shifts, half squats and short walks.
- Use the app's programs. Structured challenges give you a reason to come back and a way to track progress.
- Pair it with strength work. Balance improves faster when the hips and legs are strong, so squats and lunges are a natural complement.
Keep expectations realistic. A SlackBoard is a training tool for coordination and stability, not a substitute for medical rehabilitation, and anyone with a known balance problem should get professional guidance first.
Our verdict
GIBBON is a specialist that knows its niche well. The products are thoughtfully designed, priced sensibly for the build quality, and backed by a two-year warranty and genuinely free training content. The SlackBoard Plus is the standout for most homes, while the ClassicLine kit remains a great-value way to try slacklining outdoors.
