Almost perfect, but not...

First and foremost, I found this SUP Kayak Seat to be well designed, easy to install and adjust, comfortable and reasonably priced. After using it for two days, problems developed with the two front strap clips! One separated into two pieces and the other became "stretched" out (See pics). This occurred while simply sitting on the SUP enjoying the surrounding views. Clearly, the clips failed due to excessive force (e.g., defined as enough to make them fail). I am about 5'11" and 172lbs and I may have been sitting back in the seat vs. more upright, but one would not think this would cause such damage to the clips. I am not planning to warranty the seat, as I do think it is a good seat. The clips, however, are obviously lacking and I will be replacing them with ones that will be much stronger (Something for Thurso Surf to consider in their future manufacturing process)...

Seat pad is super-comfy, back rest is poor quality

During the first use two of the carabiners broke. I changed them to proper stronger, standard carabiners (not really meant to be used for this purpose).

Then during the second use the material got torn.

Hi,

Thank you very much for bringing this to our attention, and I’m truly sorry for your experience.

We’ve recently upgraded the carabiners on the seat to a more durable version, which should be much stronger than the original ones. However, we hadn’t anticipated issues with the backrest tearing, as this hasn’t been a common problem. I’ve already shared your feedback with our product team to review and improve the quality of the backrest in future versions.

In the meantime, we’ve processed a full refund for the seat to your account as a gesture of goodwill. We really appreciate your honest feedback and your support in helping us improve.

Stronger latches please

I’m 6’ 220lbs and after the first paddle the front latches were bending open. I replaced them with something stronger.

Love it!

First time using a SUP. I bought the Tranquility Yoga SUP specifically for stability for exercising. Haven’t fallen off yet, lol! I feel confident on the this very well made board. Plus it’s beautifully designed.

It sparkles

This really helps with the awkwardness of carrying the SUP. It helps to distribute some of the weight onto the body, so you don't have to super grip carry from the handle alone. My mom's board doesn't have the convenient little clips - but she opted not to add them herself. She's fine with looping it through the handle and clipping the ends together.I personally love how the shoulder pad glitters. Its very subtle, but a nice touch. Overall this strap seems to be made pretty well and shouldn't fall apart after one or two uses.

Really good product

Versatile. Glad I bought it.

Ultra light. I thought the box it came in was empty. Took 5 minutes to get it adjusted as I wanted but comfortable enough and I can place mats under it to lift it more if I wanted. Versatile. I've got 2 very different paddle boards and it easily transfers and adjusts to both.
The free shipping to this island where Masset is located is strongly appreciated. No free shipping from Amazon here; they charge about $150 for the smallest of parcels. Thurso Surf seems to run a pretty good business.

Sitzkomfort gut

Der Sitz lässt sich mit den Gurten leicht montieren. Man sitzt erstaunlich bequem und kann sich wirklich mit vollem Gewicht anlehnen

FAQs

Wear what you are the most comfortable in! Clothing that allows free movement is best, and clothing that won’t be too heavy when wet.

For flat water paddling you will need one centre fin. For any type of waves, or paddle surfing, look at 3, 4 and 5 fin set.
