The Sunday Sleeper

Hello Fuckoff,

A good mattress doesn’t just support your sleep, it supports your mood, your mornings, and let’s be honest, your sanity. The right one can make all the difference between tossing around and actually getting the rest you came to bed for.

For today's Sunday Sleeper, I pulled together two kinds of favorites. First up, our top king mattress pick of 2025 if you're ready to go all in on comfort. And if you're working with a budget, I’ve got you covered with the best mattresses under $500 that still feel like a win.

Sleep Better on the Best King Mattress of 2025

Nowadays, you don’t have to be royalty to own a king mattress. All you need to sleep like a king is ample floor space. King mattresses are often used by couples who want maximum room to spread out, though they are equally comfortable for single sleepers.

Our team tested over 1,000 mattresses to choose the best king mattresses available today. Our top picks include models with high-quality components and sufficient structure to provide support across the bed’s large surface area.
