Children-oriented online and catalog retailer Chasing Fireflies will lay off 92 employees in May as its corporate parent moves some operations to Ohio.

The Tukwila-based retailer was acquired in 2012 by HSNi, a Florida-based retail conglomerate that operates home shopping channel HSN as well as several catalog brands, including Chasing Fireflies, under its Cornerstone division.

HSNi spokeswoman Denise Wilson said the company expects “to optimize growth and increase our operational efficiencies” by shifting some functions. Cornerstone’s offices are in West Chester, Ohio.

The state Employment Security Department was notified that the layoffs will occur May 1.

Wilson said the laid-off employees will be offered severance and outplacement services. She added that Chasing Fireflies will move its headquarters, now located near Sea-Tac airport, to another, unspecified location in the Seattle area later this year.

When it bought Chasing Fireflies, HSNi said the purchase would allow it to enter a “fast-growing business” with unique products and strong customer loyalty. The children’s brand had generated $39 million in sales in fiscal 2011, HSNi said.

HSNi has 6,000 employees, according to its website.
