From giant flamingos to unicorns, themed floats have emerged as the hottest poolside accessory.

And now one designer has brought out a quirky inflatable that is guaranteed to get you noticed - a coffin-shaped float.

The product, which is still in the prototype stages, comes in millennial pink and features its own closeable lid just like the real thing, The Daily Mail reports.

Internet users have already gone wild for the float, and have vowed to buy it if it ever comes on sale.

The float is long enough to fit an average height woman and can be shut while its users floats out to sea or around the pool.

The float is the brainchild of Canadian designer Andrew Greenbaum, who recently posted about his creation on Instagram.

He wrote: "Had the idea to start this project almost three years ago, with my guy @ian__felton. I found someone who could make me a sample recently and pulled the trigger. Super hilarious project."

Greenbaum revealed that the company is $15,000 ($NZD16,779) short to fund the project and asked his followers if they'd consider donating.

He continued: "Let us know if you think a kickstarter would be a cool idea or if you have a rich daddy who wanna invest. We taking suggestion no doubt forsure [sic]."

The product has already proved to be popular before it's even hit shelves, as people have taken to Twitter to say how much they want one.

One tweeted: "I hate to be that person but...does it come in black?"

"Oh my god how can I get that and then have it at my desk?" another joked.

A third wrote: "When you're trying to have some fun in the sun, but you still dead inside."

"Oh my god COFFIN GOALS," another posted.

Extravagant pool floats have become so popular that even high end designers are trying to cash in on the trend.

Missoni teamed up with "luxury pool float" brand Funboy on a one-piece collaboration to create a stunning butterfly inflatable.

According to Funboy, the collaboration was a whopping 18 months in the making, and resulted in a single butterfly-shaped pool float.

The brands proclaim that it's the "world's first designer float" and it retails for $165 (£85) plus shipping.

The float comes is reversible and features two of Missoni's signature patterns, one on each side. The butterfly shape is designed so that the lounger sits between the two wings, making her (or him) the butterfly.

Each of the patterns were screenprinted by hand.
