Sleep Number mattress. Yes it’s gimmicky and expensive, but the ability to adjust softness/firmness according to how my back feels is priceless
iPad. A long time ago when I was an IT drone the boss dropped a 1st gen on our desks and said, “set it up and figure it out, you’ll be supporting it.” 2 weeks later I told my husband he was off the hook for Christmas, I wanted one of these. It’s been my most used entertainment tech since through multiple generations
I second the sleep number bed. Ours is 17 years old and I’d say it feels like new but it actually feels better since we added a plushy foam pillow top. It’s as soft or firm as you want it. Love it.
I use an android tablet and agree with the tablet as a gamechanger. I use it in my line of work (entertainment) and using it in front of clients makes you look professional as hell.
