    Booked Foam O Clock for my daughter's 8th birthday and it was the highlight of the summer. The foam was insane, the kids didn't stop screaming for an hour, and cleanup was way easier than I expected. Already telling friends. Worth every penny.

    Hired these guys for our church youth group event in Longmont. Showed up on time, super friendly, and the foam was completely safe — no eye irritation or anything. Adam knew what he was doing. Will book again next summer.

    Got the pink and blue colored foam for my niece's gender reveal style birthday party. It looked unreal in the photos and the kids LOVED it. Setup was quick, they brought their own music, and we didn't have to lift a finger. 10/10.
