Popular home furnishings retailer At Home has filed for Chapter 11 bankruptcy protection and plans to close dozens of stores, according to court documents and company statements.

The retailer, which has 260 retail locations across 40 states — including two on Long Island — filed for bankruptcy in U.S. Bankruptcy Court in Delaware on Monday. The company said in its court filing that inflation in recent years and the "unsustainable customs costs resulting from increased tariffs" had put financial strain on the retailer.

The company, headquartered in Plano, Texas, said in its filing it planned to transfer ownership to At Home’s lenders and close 26 underperforming stores by Sept. 30.

The bankruptcy restructuring will "eliminate substantially all" of At Home’s nearly $2 billion in debt and provide an infusion of $200 million to support the company as it transitions ownership, the company said in a news release.

At Home representatives referred Newsday’s inquiries about the bankruptcy filing and planned closures to the company’s statement and court filings.

The chain has two locations on Long Island, at 4000 Jericho Tpke. in East Northport and 5151 Sunrise Hwy. in Bohemia. Neither of those stores are slated for closure, according to court documents.

"While we have made significant progress advancing our initiatives to date, we are operating against the backdrop of an increasingly dynamic and rapidly evolving trade environment as we navigate the impact of tariffs," Brad Weston, chief executive of At Home, said in statement.

Weston said the restructuring and change in ownership would improve the company’s ability to compete "in the face of continued volatility and increase the resilience of our business for the long term."

Although tariffs and increased costs had impacted the store, retail analyst Neil Saunders said debt was the driving factor.

"The main problem for At Home is the extensive debt that the company had on its balance sheet," Saunders, managing director of GlobalData, a Manhattan-based retail analysis firm, said in an email. "This was not sustainable and its elimination under Chapter 11 will provide a more stable basis on which the company can operate."

Saunders said debt was not the only factor at play.

"At Home is also suffering from the slowdown in consumer demand for home furnishings, which is partly a consequence of low consumer confidence and a sluggish housing market," Saunders said.

Locally, the number of furniture retailers on the Island, particularly mom-and-pop operations, has been on the decline, Newsday has reported.

"These dynamics are unlikely to change in the near term," Saunders said.
