Balance training helps build core strength, stability, coordination, and body awareness, so you can move with more confidence in everyday life and perform better in the activities you love. It also challenges the small stabilizing muscles that support better movement, mobility, and reaction time. Whether you’re an athlete, a kid, or just want to stay active and steady, better balance benefits every body.

We’re confident you’ll love your GIBBON product. If it’s not the right fit, you can return it within 30 days for a full refund, minus return shipping costs.

Weight limits vary by product. For SlackBoards, the SlackRack, and SlackYard, we recommend a maximum user weight of 400 lb (181 kg). For Slacklines, we recommend one person at a time, with a maximum user weight of 250 lb (113 kg).

For balance and core training at home, start with a SlackBoard. It’s compact, easy to use, and works indoors or outside.

Want the feel of slacklining without needing trees? Choose a SlackRack for a freestanding setup you can use indoors or outside, or a SlackYard for a backyard setup on grass.

Have two trees? Go with a classic SlackLine.

GIBBON is for all ages and ability levels, from kids and first-timers to athletes and older adults. If you’re new to balance training or want more stability, the SlackBoard Plus is a great place to start.

UK orders ship from Manchester. Delivery typically takes 2–3 business days after dispatch, and you’ll receive an email with tracking information. See our shipping policy for details.

For the best performance, we recommend 400 lb (181 kg) or less. Heavier users may find the line loses tension a little faster, which is normal and easy to fix by re-tensioning.

Just about anywhere! Use it on hard floors, carpet, outdoors, even at the beach. Since it’s made of wood, keep it out of the rain and don’t leave it in direct sunlight for long periods.

Yes. Kids build balance, coordination, and confidence while they play, and the low profile makes it easy to step off. It’s a fun, screen-free way to burn off energy, and the free GIBBON app includes programs for kids.

Yes! The low-to-the-ground design makes the SlackBoard great for beginners. Even though balancing on the line is challenging, because your foot is so close to the ground, it's easy to restart once you lose your balance.

Nope! Your SlackBoard arrives fully assembled, with the line already installed and tensioned. Just unbox it and step on.

Every board includes a tensioning dowel and instructions to re-tension anytime. The SlackBoard Plus and Pro also include everything you need to switch between one- and two-line setups.

Yes. In an 8-week UCLA study, people who trained on a SlackBoard improved their balance more than those who trained with conventional balance training tools. Read the full study on our Science page.

The SlackBoard is our original full-size, single-line balance board. It’s a great choice for anyone looking to challenge their balance, build strength and coordination, and progress their balance training.

The SlackBoard Plus is also full-size, but comes with two lines for a wider, more stable platform and can be easily converted to a single-line setup. It’s our most versatile option and is great for beginners, kids, workouts, recovery, and standing desks.

The SlackBoard Pro is built for gyms, sports performance facilities, and physical therapy clinics. Like the SlackBoard Plus, it switches between one and two lines, and it has larger neoprene pads on the bottom for added durability and grip.

The SlackBoard, SlackBoard Plus, and SlackBoard Pro all support up to 400 lb (181 kg).

No, the design is just the artwork. The model is what changes how the board works: the single-line SlackBoard, the two-line SlackBoard Plus, or the commercial SlackBoard Pro. Pick the model that fits how you’ll train, then choose the design you love.

No. The original single-line SlackBoard cannot be converted to a two-line setup. If you want the flexibility to switch between one and two lines, we recommend the SlackBoard Plus.

The SlackBoard is compact and easy to move or store.

• Dimensions: 42" L x 11" W x 5.5" H
• Weight: 7.5 lb (3.4 kg)

Absolutely! The SlackBoard sits low to the ground, so if you lose your balance, you just step off and try again.

We’re confident you’ll love your SlackBoard. If it’s not the right fit, you can return it within 30 days for a full refund, minus return shipping costs.

We offer a 2-year warranty on all GIBBON products, which covers manufacturing defects or failure caused by normal use.

Your SlackBoard arrives fully assembled with the line already installed, so you’re ready to get started. It also includes the Roll and Lock dowels, line clip, and tensioning rod.

The original SlackBoard has one line and is great if balance training is your main goal. Even a few minutes a day works your lower body and core. The SlackBoard Plus comes with two lines for a wider, more stable platform. Most first-timers find it easier, and it’s great for squats, standing desks, kids, and older adults. When you’re ready for more of a challenge, use the included clip to switch it to a single line. It’s like getting two boards in one.

No. The standard SlackBoard is designed as a single-line board and can't be converted. If you want to switch between one and two lines, choose the SlackBoard Plus or Pro.

Yes. The SlackYard is a freestanding option for grass or compact soil and lets you start just a few inches off the ground. The SlackRack is a portable freestanding frame you can use indoors or outside.

It's always recommended. GIBBON Treewear protects both the tree and your webbing from abrasion.

Start by standing on one foot. Keep your back straight, your arms up, your knee softly bent, and breathe deeply. Once you can stand comfortably on each leg, start taking your first steps. Your leg will shake a lot at first, and that’s normal. With practice, it settles down.

Below the user's hip height, but high enough that the line doesn't touch the ground when someone is standing or walking on it. If you're just starting out, keep it low.

You can set up your slackline up to the maximum length listed on the product page, minus the distance around both trees. A shorter line is easier when you’re starting out.

For most beginners, don't exceed 100 lbs of tension. Usually you only need enough tension that the line vibrates when you flick it with your finger.

Like any sport, slacklining has some risk. Start within your ability, with the line short and low to the ground. As you progress, you can lengthen the line and raise it for more challenge.

It’s personal preference. If you wear shoes, choose a flat rubber sole. Never slackline in heels or shoes with a lugged sole.

Slacklining is suitable for all ages. We recommend that children under 12 use slacklines only with support and supervision.

Our slacklines are rated between 3,000 and 6,000 lbs depending on the model. For safe use, we recommend one person at a time and a maximum user weight of 250 lbs.

Start with a 2" line like the ClassicLine series or the TravelLine. These lines stretch less, allowing lower, more stable setups, and the printed webbing adds grip for those first steps.

Our slacklines vary in length, width, and design, but the biggest difference is how much the line stretches. If you want to do tricks and jumps, choose a more dynamic line like the JibLine or SurferLine.

Yes. The Plus and Pro use 2 large clips for two lines and 1 small clip for one line. The single-line board uses 1 small clip. The Replacement Bundle includes 2 large clips and 1 small clip.

Yes. The SlackBoard Wood Dowel Kit includes replacement Roll and Lock dowels identical to the ones that come with a new SlackBoard.

We don’t offer custom SlackBoard lines at this time. However, you can mix things up by purchasing different color lines.

Yes. You can return individual items from a bundle—you don’t need to return the entire bundle. Your refund will be based on the value of the item(s) being returned, minus any applicable return shipping costs.

Yes! If you order accessories with your SlackBoard, they’ll ship together in the same box. Be sure to check the entire box when unpacking, as smaller accessories may be tucked underneath the board.

The Stand, Pole and Trigger Ball work with both.

Yes: Starter, Support, Recovery, and Support & Recovery bundles.

Yes. GIBBON eGift Cards come in $10 to $250 amounts and are delivered by email.

If you need extra leverage when re-tensioning your line, the SlackBoard Tensioning Strap makes the job easier.

The main difference is how they feel underfoot. The 1" line provides a more traditional slackline experience with a narrower surface and more dynamic feel. The 1.5" line offers a little more surface area underfoot while still delivering the movement and challenge of slacklining.

The SlackBoard Stand, Pole, Marble Trainer and Trigger Ball work with single-line and two-line SlackBoards.

Unlikely. SlackBoard lines are made to last the life of the board.
