Backstory: I saw a recent reddit post talked about how recent studies say adults fall asleep faster and sleep longer when they are rocked to sleep.

The Idea: A bed that rocks you to sleep.

Deep Dive: This is a big undertaking, building a physical, rocking bed for adults. This would most likely involve patents and a big investment.

Validation: There already exists one https://rockingbed.com/ but as we've seen in memory foam beds, there can be plenty in the space. The snoo exists for babies and is very highly rated.

Monetization: This is another straight ecommerce play, you would charge for your product, just watch your margins!
