Texas has seen more than its fair share of weather-related calamities-but there's one valiant businessman who has consistently stepped up to make sure his Houston neighbors always have shelter from the storm.

When the recent winter storm, Uri, took out the power grid, leaving the state in shambles, Jim "Mattress Mack" McIngvale opened two of his Gallery Furniture locations as impromptu warming stations.

Over the course of a 72-hour period, Mattress Mack and his crew provided 3,000-plus meals and overnight accommodations to more than 700 Houston residents, after offering shelter to the community on the store's website.

And, this isn't the first time Mattress Mack turned into a Good Samaritan. In 2005, the Lone Star paladin welcomed refugees from Hurricane Katrina, and in 2017, he gave succor to victims of Hurricane Harvey.

"We're opening up both buildings as shelters during this horrible time," McIngvale said in a 2017 post to the company Facebook page. "We've got lots of beds, we've got lots of food, we got water, and you can even bring your animals."

When tropical storm Imelda hit in 2019, once again, McIngvale made sure Furniture Gallery's doors were open for those in need. With the onset of Uri, he took to social media, inviting anyone who needed to, to come on down.

While the store had a diesel-run generator to provide electricity, with only a single functional water pipe, plumbing became a critical issue. Ensuring COVID-19 protocols were followed added another layer of complexity to the situation.

McIngvale and his staff rose to the occasion, rigging a solution to meet the plumbing demand, and also ensuring that once visitors were wearing masks, they observed proper social distancing before settling in to fill up on warm meals, watch some TV, and get some much-needed rest.

"Obviously there's a lot of angst among the community coming in here. They're shellshocked. They've been home for days in the cold with no electricity, no heat, no water, no plumbing," McIngvale told The Washington Post.

While McIngvale may best be known locally for the over-the-top commercials that have made Mattress Mack a household name for three decades, he's been getting some king-sized praise via the Internet from the west coast to the east for being the go-to humanitarian port in so many Houston storms.

"I live nowhere near Texas, I'm in Michigan," one Facebooker posted. "If for whatever reason I ever move to Texas, be sure you'll have my patronage! Thank you for your kindness."

And this from the Windy City: "Shoutout to Mattress Mac from Chicago! You are An absolute blessing to those in need and an inspiration to everyone. This story has done so much more than warm and feed Texans-it is a beacon of light and hope for our entire country. You are a true angel!"

And this one from the South: "I live in Georgia and this is something that warms my heart. I know y'all are cool and hungry and to read something like this is amazing. Thank you Gallery Furniture for doing this. God bless."

Much of the expense for his neighbors' care comes out of McIngvale's own pocket, but to him, that's how it should be. "To whom much has been given, much is expected," McIngvale told The Post. "We've benefited from public support over the years, so it's our obligation to open our doors and let people come in to get a respite from the storm. It's the right thing to do."

For anyone who'd like to help an angel out, McIngvale has set up a GoFundMe campaign to help alleviate the ongoing storm-related impact on his community.
