In season 17, episode 12 of ABC’s ‘Shark Tank,’ The Chair Blanket stepped in with an innovative product designed to eliminate these hassles. By combining comfort with practicality, it offers a simple way to keep everyday seating clean, cozy, and always ready to use without constant upkeep.

The appearance of Tiffany and Chris McCasland, the co-founders of The Chair Blanket, on ‘Shark Tank’ proved to be a pivotal moment for the brand. The exposure not only served as a catalyst for growth and awareness but also validated the product’s positioning in the market.

Chris and Tiffany McCasland, the husband-and-wife duo behind Maryland-based supplier City Bonfires (PPAI 814515, Standard-Base), will appear on Shark Tank on Wednesday, March 4, at 10 p.m. ET on ABC and stream next day on Hulu. They will be pitching on behalf of their newest company, The Chair Blanket. The eponymous product combines fleece on one side with a waterproof backing on the other to transform any chair into a warm, dry and comfortable retreat. “The speed at which The Chair Blanket has grown has been incredible,” says Tiffany, CEO and co-founder of The Chair Blanket. “Families, sports fans and outdoor lovers instantly understand it. Once you use it, you don’t want to sit without it.”

“We’ve sacrificed a lot to build this,” Tiffany McCasland said. “But being able to create jobs — especially for family and for people in the county — is really important to us.

Rockville entrepreneurs Tiffany and Chris McCasland, co-founders of The Chair Blanket, are scheduled to appear on Shark Tank on March 4 at 10pm on ABC. The couple will pitch their outdoor lifestyle product, which launched in fall 2024 and features a dual-sided design with a waterproof exterior and fleece lining intended to keep outdoor chairs dry and users warm.

“This is one of those simple but brilliant product ideas that I wish I would have thought of. This would be perfect for those early season track meets and late season cross county meets, bonfires out in the driveway and more. I also love that the blanket comes in a variety of colors and patterns.”

After a night of snow flurries, the water-resistant coating shed moisture with just a quick shake. It's big enough to share but light enough to pack down small for car camping or tailgates. I even used it inside my tent as an extra thermal layer over my sleeping bag, and it noticeably boosted warmth. After a weekend of damp mornings, it still looked and smelled like new after a quick wash.
