"I think in my 30 years, this is the best mattress I have slept on. I like to sleep on the floor and this is closest to it. You don't feel like sinking into the bed. You can change side confidently and effortlessly. I even have pain in my arms and shoulders due to a cervical disk issue but I have no issues sleeping on this hard mattress and I like it."
"We just started sleeping on it. It is installed on a FlexiSpot platform bed, no box spring. We have it right side up as illustrated in the ad, we are assuming thats the regular way and upside down is the super firm orientation? Regardless with it flipped as the logo reads correctly right side up as in the photos its a very comfortable mattress. I am a side sleeper and its still nowhere near too form for me. My wife also really likes this mattress and she is typically a side sleeper as well. I’m 5’8 205lb, my wife is considerably smaller and lighter, we are both primarily side sleepers and we both find it comfortable. Also its solid enough that when I flip from one side to the other it doesnt wake her. Good purchase. We are pretty happy so far."
"I've been buying beds from Brooklyn Bedding since 2021. Quality, firm beds every time. I grew up sleeping on the floor, so a firmer bed was always necessary. Brooklyn bedding firm bed choices will always be my go-to until the day I die"
"I waited to sleep on this mattress a few weeks before submitting a review. I like to sleep on my side, back and stomach and if the mattress is too soft, I wake up with lower back pain. Im in my late 50’s & weigh 225 to provide some background. This Plank mattress has been great for my wife and I. We sleep on the softer side of the mattress (#8 of 10 firmness) and love it. The first two days we woke up a little achy until we adjusted from our old mattress but now, this has been a purchase we don’t regret. We love the firmness and there is very little movement to wake the other when one of us turns over during the night. We would definitely recommend it for someone who sleeps in multiple positions and/or experiences lower back pain from sleeping."
"This may be the best mattress I've ever owned. It is super firm, well put together and when we opened it up there was never once any chemical smell or off-gassing like we've experienced in the past from manufactured foam mattresses. Very impressed with the quality!"
"It's been less than a month of sleeping on your mattress. I've only slept on one side. And, as I can find no notation distinguishing firm from extra-firm, I'm not sure which side I've been sleeping on. Perhaps another review would be merited in 3-6 months."
"Husband and wife, both 200 pounds and more. Sleeping on the firmest side with a thin "My Pillow" on top of the mattress which gives just enough cushion when sleeping on back or side. Much better than the old worn-out mattress."
"This mattress is for our guest room because we love our personal mattress so much. We love the firmness and the ability to turn it over if you want it firmer. My daughter has even bought one."
"Motion isolation barely exist. I put my coffee down for 2 seconds and my son from the other side caused it to tip over. Luckily I had a protective cover on it. The softer side is not bad for soft but the harder side is not that firm. It collapses under weight and I feel the springs. Over all I rate it a 3. 5 out of 5 because although firmer than most mattresses, for the price point it feels cheaply made."
"Nice and firm. The only negative is when I’m sitting with my head at the headboard, the mattress slopes down to the edge so I have to periodically scootch myself back toward the center."
