There’s a fantastic book series based on exactly this: The Change Series. This is a double storyline with the Emberverse series in which the present time beginning in March 1998 loses electricity and “most forms of high-energy-density technology” due to “The Change”, which occurs at 6:15 p.m. Pacific Standard Time, March 17, 1998.
The companion series, which was written first, is the Nantucket Series, in which the island of Nantucket is transported back in time to 1250 BC due to something called “The Event”, the same Event that caused The Change. But— they got to keep all their physics intact.
I bit the bullet in 2017 and got a Stearns and Foster mattress set. I think it was less than $2k for the set, queen size, at City Mattress, and they had a “zero percent interest for a year” thing going on. It’s one of the best purchases I’ve ever made.
You’ll find them for much higher prices online, it was going to the store that got me the deal. Find a mattress store near you that carries that brand and you may find a deal, too. It’ll save your back and you’ll sleep so much better.
They’re turning down the free steak because the [insert ethnicity/whatever difference here] person might get one too.
