I mean it's got the 'Splosh' branding and everything.... as well as something like this should work pretty good for an inflatable messy "wrestling" mat.

[I do not own the images, they're taken directly from the product listing]

Nice idea, although with anything like this you need to check the dimensions carefully.

The box says "180cm x 120xm" (sic)

One of the photos says that it's 173cm long and 120cm wide, but that's the outer dimensions. I.e. the bit you sit in will be smaller than that (but the exact size isn't specified).

My guess is that they either found the smallest models they could to pose for photos or they did some Photoshop.

Would have loved to try these, you can get bigger ones, just search for 'inflatable raft'. Also inflatable boat gets you similar things but with stronger plastic.

Also look at inflatable baths if you want depth over length (yeah, I know...)

As for photoshop; definitely, just look at the feet. No shadow and slightly square toes.

The models are always photoshopped in on stuff like this. Or the inflatable itself is [badly] photoshopped.
Seen a 5m by 2m by 1m deep inflatable pool advertised, and the "product photos" showed it filled to the brim with perfectly straight sides... Thats 10 tonnes of water in there- no inflatable is holding it straight.

I laughed audibly when I saw "Splosh". Either wammer speak or engrish.

There are quite a few on the market right now. This one is not only huge, it has beverage holders and romantic lighting. Ohhh, baby.

Interesting possibility and definitely like the idea - though as mentioned, "173cm long and 120cm wide" - and likely that is the max or outer dimensions. Probably take 20cm or more off each dimension for the outer 'padding' So, more like 150x100 - or in 'American', that is a bit over 5-1/2 feet long and a bit under 4 feet wide, outside...so maybe an actual 'sploshing' area of 4-1/2 feet x 3 feet?

A lot of the reviews seem to support this, suggesting it's actually smaller than it seems - or that the model in the picture must be 4 ft / 120cm tall.

If there was a banana cream pie sitting next to her, then I'd be sold.
