Looking at their website, it looks like they have ditched the mascot altogether and revamped the logo to a black font with yellow stars. Pretty boring.
Right before I started my first job out of college, I bought a mattress from Sleepy’s and was grossly overcharged. My mother returned to the store and berated the salesman for taking advantage of a young girl who didn’t know better. He retroactively gave her a discount and that was my last experience with Sleepy’s.
