At first glance, the catalog's pitch for lawn chairs appears ordinary: A seated man and woman relax near a tree-lined lake shore, enjoying drinks. But look closer. "Supports up to 800 lbs," reads the text next to the man's $139.95 lawn chair. Flip deeper into the catalog, and the products get even more specialized, such as a "Big John" toilet seat with a 1,200-pound capacity - "larger than any other toilet seat in the world" - priced at $124.95.

The products are in "LivingXL," an online and print catalog launched in May by the parent company of Casual Male XL, the nation's largest chain of men's plus-size clothing and apparel stores. Casual Male Retail Group hopes to parlay the marketing know-how from its 500 stores into the largely untapped market for specialty products that make life easier for the growing population of obese men and women.

The Canton, Mass.-based chain is the first large retailer to enter the niche, now served by a handful of mom-and-pop catalog and online retailers offering a limited selection of products with little marketing glitz.

For Peggy Howell, a 300-pound woman who runs an online store featuring art with positive depictions of heavy people, Living XL could help her more easily find products that give her confidence.

"When I'm trying to buy lawn chairs, I want to get one that's wide and sturdy," Howell said. "My sister and I share a home in Las Vegas, and whenever we go to a party or an event, we take our special collapsible lawn chairs. We know we'll feel secure in them, and comfortable.

"You can find these kinds of specialty things once in a while, but they're not always easy to find," she said. "When you do, you tell all your friends."

LivingXL is the new incarnation of www.SuperSizeWorld.com, a Vancouver, Wash.-based online store that Casual Male bought for $400,000 last October. Casual Male Chief Executive David Levin learned about the business while reading an article on obesity last fall during a business trip.

The switch to a new name was in keeping with the company's re-branding of its stores last year from the old name Casual Male Big & Tall to Casual Male XL - a move that dropped the word "big" to eliminate a term often seen as a code word for "fat" in the euphemism-rich world of retail branding.

"We knew from our Casual Male stores that they didn't like 'Big & Tall,'" Levin said, "and they certainly wouldn't like 'SuperSize,' especially with that movie 'Super Size Me'<0x200A><0x200A><0x200A>" - a 2004 documentary about an independent filmmaker's experiment of eating nothing but food from McDonald's for 30 days.

Levin is trim, but claims to understand the daily challenges heavier people face, in part because the company convened a focus group of overweight people to develop the catalog.

The group helped Casual Male navigate the idiosyncrasies of marketing lifestyle products to heavy people, who often feel stigmatized about their weight, even though they're greater in number than ever before.

An estimated two-thirds of American adults are overweight or obese, compared with 47 percent from a survey done in the late 1970s, according to federal statistics.

A public health advocate welcomes the marketplace's efforts to reach out to the growing ranks of overweight people, but also cautions against instilling any sense of complacency among heavy folks. Obesity raises the risk of heart disease, diabetes, arthritis and some cancers.

"It's a balancing act between assisting people coping with the results of being obese, and not losing track of the public health message about being more active and eating healthier diets," said Jeff Levi, executive director of the Trust for America's Health, a Washington-based nonprofit. "But if we stigmatize obesity, it makes the public health challenge that much more difficult."
