Allswell, Walmart's online mattress-and-bedding brand, unveiled a tiny-home model in New York City.

The model will soon head to various US cities, giving people the option to buy items as they tour inside.

The home is also available to purchase for $100,000.

Companies are beginning to see tiny homes as an interactive way to showcase their brands.

Tiny homes have caught on for several reasons. They can conserve energy, save on mortgage costs, and encourage a more mobile lifestyle. Most recently, they've become a popular branding technique for major companies.

In November, Dunkin' Donuts unveiled a tiny home that ran almost entirely on coffee. The home was briefly listed on Airbnb for $10 a night, and guests were offered an unlimited supply of Dunkin' roasts.

Three months later, Allswell, Walmart's online mattress-and-bedding brand, has adopted a similar strategy for showcasing its products.

On Thursday, the brand began offering tours of its tiny home — with a bedroom, a kitchen, a bathroom, and a living room — in New York City. People can test the mattresses and bedding, with the option to purchase items on-site and have them shipped to their home.

The tiny home will soon make its way across the country, stopping in cities like Philadelphia, Nashville, Los Angeles, and San Francisco. Allswell is also selling one tiny-home model for $100,000.

Take a look at how the brand incorporated its first retail experience into less than 240 square feet.
