Hi the mattress is outstanding, an certainly for the price I paid, I would certainly & honestly recommend for anyone with back injuries or pain I myself have had extensive surgery (see the photo I provided), unfortunately I still have to manage my pain daily but thanks to this mattress i genuinely have a brighter outlook on life, I noticed significant decompression in my lower back after 2 days an for that I thank your company. Sincerely Marcus Sivkoff
