Industry Reviews

FORBES

"Along with its impressive firmness and value, we named the Plank Firm best firm mattress overall because it tested well for back and stomach sleeping, ease of movement, edge support and motion isolation—all key categories that determine the quality of a firm bed."

FORBES
MATTRESS CLARITY

"The Plank Firm Luxe is the best firm mattress because it delivers what firm-mattress shoppers are looking for: an ultra-sturdy, flippable design with two genuinely firm options that outperform and out-firm many other options on the market."

MATTRESS CLARITY
SLEEP FOUNDATION

“The Plank Firm Luxe is a flippable mattress with a firm (7) feel on one side and an extra firm (9) feel on the other. The latter is one of the firmest, most supportive surfaces our team has personally tested."

Reviews

I've been using this topper

"I've been using this topper for about 10 days and it has already improved my sleept. I have a lot of low back issues and nerve pain. My newish mattress was only 3 years old and has already become soft. This 10/10 firmness mattress topper really helped and was more cost efficient than another mattress. I hope that this topper will continue to hold up over the next 30 days while its still under warranty. Overall very happy"

"Love it"

Giving it time

"So far it seems better than my 2 year old mattress that I put it on top of. Some aches were alleviated. I do think I'm sleeping more soundly. It still wants to move to the side I get off and on the bed. Besides the straps it has, my sheet has straps that should further secure it but I have to realign it often. I haven't had it a month yet so I'm still on the fence and giving it time."

— Vicki L. (4/5)

"It slides off the edge everyday. It looked like it came with straps to hold it in place. But didn't have any straps."

— Timothy (4/5)

We would of liked it

"We would of liked it firmer"

— James G. (3/5)

Not worth the money

"I purchased the "extra firm" topper to add support to my current mattress. It is far from firm, I actually sink in when I lie down and the first week trying to use it, I woke up with lower back pain. It's now laying in the junk room. Guess I can use it when I go camping to put on the ground."

— Richard H. (1/5)
