Plank Mattress reviews and discussion

I love a really firm mattres and this company advertises itself as selling "the firmest mattress ever." Definitely hyperbole, but it is the firmest foam mattress I have tried, and it works for people who like medium firmness as well. The website ordering was easy and it has a 120 night return policy. They offer both foam-only and hybrid models as well as the usual add-ons that seem to appear on all DTC mattress companies these days like special pillows, mattress covers, and adjustable bases. I just got the mattress and although I would personally consider this an 8 out of 10 on the firmness scale, its better than any other mattress advertised as firm that I have tried. I also like that it is two sided, with one side being more firm and the other being less firm, so you can make some sensory choices after you've purchased.
