Plank Firm on its firmer side felt soft, nowhere near firm, with weak edges; looking to return it.
“I bought the plank firm, seeing how it's allegedly the firmest mattress around, something like 9/10.”

Plank Firm (not Luxe): the firmer side fixed mid-back pain but a dip and side-wall bulge appeared by day 90, so they returned it.
“after a couple more weeks we decided to return it.”
Plank Firm felt like the softest mail-order bed he had slept on and he sank in at 205 lb; a solid foundation later made it 'night and day'.
“I'm not being hyperbolic, it's the softest mail-order mattress I've ever slept on.”
Plank Firm after six months: no sagging at all with about 350 lb of combined weight.
“It’s working out amazingly no sagging at all. It handles about 350ish pounds with me and my partner combined.”
Replaced a Saatva that did not stay firm with a Plank Firm king (about $1,100); very firm and still liked 18 months in.
“It’s quite firm! 18 months in, we still like it.”
The Plank is the best mattress they have had and very firm.
“I bought "the plank" and it's the best mattress I've ever had.”
