Best foam mattress! Took about 48hrs to fully expand and have had the best sleep ever in such a long time. Ive tried plush with pillow tops and Ive tried firm and really thought there was no fix to my sleepless nights but this medium foam is perfect for my adjustable base bed and I no longer have try all the toppers Ive tried. Its very breathable so I dont wake up hot or sweaty or wake up freezing. Im just so excited to have found this mattress and would absolutely recommend !
