8 Mattresses You'll Definitely Regret Buying: Avoid These Sleep Nightmares!

6. Bear Mattress (Original)

Bear-ly functional.

The Bear Mattress is marketed to athletes, but if you're not training for the Olympics, you might find it a bit too firm for your liking. It's got a cooling cover, which is great in theory --- until you realize it's just a thin piece of fabric that doesn't do much. This mattress is "supportive," alright... but you'll probably end up feeling like a stiff board.
