ULTRA Seat with Flex Pod Suspension No Plinth

The starting point for any jockey seat ULTRA is the flagship model, adaptable and reliable for both recreational and military markets. Users can customize it with upgrades from our modular system or keep it simple.

Affordable, comfortable, & safe suspension seats for boats

At Shark, it is all about you and your safety.  Our mission is to save your neck, back, knees, and ankles with the most comfortable suspension seating possible and save your budget at the same time.

Simplicity & Quality meet Hi-tech

The simple design, combined with hi-tech tooling and robotics, provides a consistent, quality result every time. This investment on our part ensures the best quality, price, and on-time delivery for you.  There is also nothing to rust, no coatings to peel, just high-tech UV-protected Flexanite™ with colour that is molded all the way through.

Peak Performance, Independently Tested

Regular suspension seats for boats, which use scissor action or telescopic designs, have crush points and aren’t able to match the 9″ range of motion and 3D protection in every direction unique to Shark Flex. This is handy because waves don’t just throw you up and down. With just one moving part, Flex is more reliable and easier to service than anything else out there. In fact, Flex has been tested to stringent Nato standards and easily survives 1 million test impacts at 10G.

Comfortable & Attractive

Shark suspension seats are more than just an ultra-light and robust gadget to save your back. They are comfortable and look great while doing it, too. Thanks to the elegant design and huge 225mm of vertical travel, your back is protected, even over the biggest waves.

Your comfort is important to us, which is why we have combined this large travel with our energy-absorbing foams to make it feel like you are riding on a cloud.

The saddle shape of the seat also keeps you anchored and feeling secure; you never feel like you will be thrown off, not even sideways. The seat pommel supports you sideways so securely that you can relax your arms and concentrate on more important things like controlling the boat or enjoying the ride.

Safe

Shark seats are made to last because your safety comes first.  This is why we test our suspensions 5 different ways (life tests, crash tests, drop tests, pull tests, and field trials) to make sure they stay tough when the seas are rough.

Our commitment to you is to provide a safer and more enjoyable boating experience and make that accessible to everyone, regardless of the size of your boat or budget, or where you are. Trust Shark and you will never look back.

Great Product
Size: 90 Count (Pack of 1)
Life Extension’s Neuro-Mag Magnesium L-Threonate is a standout supplement designed to support cognitive health, and after trying it for several months, I can see why it’s so highly regarded. This product contains magnesium L-threonate, a unique form of magnesium that’s specifically formulated to cross the blood-brain barrier, making it highly effective for brain health. Each serving (three vegetarian capsules or one scoop of the tropical punch powder) delivers 2,000 mg of magnesium L-threonate, providing 144 mg of elemental magnesium. Here’s my take on its performance, benefits, and overall experience. Pros: • Cognitive Support: I noticed improved mental clarity and focus after about two weeks of consistent use. Tasks that require working memory, like recalling details or multitasking, felt smoother and less taxing. This aligns with research indicating magnesium L-threonate’s ability to enhance synaptic density and cognitive function, particularly in aging individuals. • Sleep Benefits: While not marketed primarily for sleep, I found that taking it about an hour before bed helped me fall asleep faster and wake up feeling refreshed. This echoes user experiences shared on platforms like X, where some reported better sleep quality and daytime alertness. • High Absorption: Unlike other magnesium forms like oxide or citrate, which are better for whole-body benefits, magnesium L-threonate is designed for brain absorption. Studies cited by Life Extension show it can boost magnesium levels in cerebrospinal fluid by 15% in animal models, which likely contributes to its cognitive effects. • Clean Formula: The capsules are gluten-free, non-GMO, and vegetarian, with no major allergens or unnecessary fillers. The powder version has a pleasant tropical punch flavor, making it easy to mix with water or juice. • Trusted Brand: Life Extension’s rigorous testing for purity and potency gives confidence in the product’s quality. Their transparency, including offering Certificates of Analysis, is reassuring. Cons: • Price Point: Neuro-Mag is pricier than standard magnesium supplements, which might be a drawback for budget-conscious buyers. However, the specialized form and targeted benefits justify the cost for those prioritizing brain health. • Time to Notice Effects: While some users report benefits in as little as six weeks, full effects may take up to 12 weeks, requiring patience. Final Verdict: Life Extension’s Neuro-Mag Magnesium L-Threonate is a high-quality supplement that delivers on its promise of supporting cognitive health. Its ability to enhance memory, focus, and even sleep quality makes it a worthwhile investment for those prioritizing brain function. Great benefits and clean formulation make it a top choice!

Highly recommend for sleep, mood, mental health
Size: 90 Count (Pack of 1)
I recently re-discovered this supplement, and I'm buying extras left and right and recommending to everyone I talk to. I've been working on increasing my HRV and supporting my nervous system, and the L-threonate is a rockstar for that. I was taking glycinate for a few months, and I found an old bottle of this one and added just 2 capsules, and the effect on my sleep was immediate. Way better than melatonin. My Fitbit is tracking much lower restlessness and more deep sleep, and I actually wake up feeling refreshed ?? and before my alarm, even! I'm noticing lower anxiety and an overall better mood, and it's only been 4 days. This bottle definitely holds its value, and the price is good, especially if I can get these benefits with just the 2 caps and not 3.

Big winner for helping BETTER SLEEP
Size: 90 Count (Pack of 1)
Life Extension is top of the line on most things they have. also pricier than most, but I buy three items for them regularly for many years. This Neuro-Mag with L-Threonate is excellent for boosting better sleep. This is a newer addition to their line. I also suggest trying their Mult-B complex and their B-12 elite (sublingual) On nearly all items, their quality control is near THE TOP of all suppliers. They also have supported vitamin and supplement research on my items over the last 40 years
