This mattress is VERY firm.  One place I saw the Lucid Plush give a rating of 6 on a 1 to 10 scale of firmness.  By that rating, this one would be an 8 or 9.  It made my whole body hurt.  We returned it after only two weeks.  Thank you Wayfair for your 100 night guarantee!  The return was so easy! They picked this mattress up right off my porch.  They came after the new one was delivered, and everything worked out great.
