About this item

Product details

This dual-sided ultra firm mattress allows you to choose between the firmest sleep experience available—or a medium-firm sleep experience. The choice is yours with just a flip of your mattress. This sleep surface is inspired by the minimalist approach to sleep found in places like East Asia, while including a more modern mattress design. Enjoy relief from back pain with a sleep surface that helps you achieve a neutral spine while also aiding proper blood circulation and better oxygen intake. The firmest mattress available, guaranteed. (Available with an optional sewn-on cooling cover from high tech PE fibers.)

Very tall, very firm, oh so good.

I think this might be too firm for most people, but for me it's PERFECT! Out of the box it was super firm. It has gotten a touch softer after being broken in a bit and now it's perfect. I would probably recommend getting the slimmer version because the tall one is a bit too tall if you have an elevated bed frame.

5 out of 5 stars review

I slept on a hotel

I slept on a hotel bed while on a trip and it was probably the firmest bed I ever slept on. I loved it. I've always bought "firm" mattresses in the past but they were never as firm as that hotel bed. I googled what's the firmest mattress on the market and was led to Brooklyn Bedding. Found the plank, bought the California king because I'm 6'2". The plank is easily the best and firmest mattress I've ever bought. I honestly am in love with it!
