Excellent product I knew from buying it for my daughter, since I had been sleeping on bad mattresses for several years, the first night was a little rough, the mattress is indeed firm, but when I woke up despite the little sleep, the body didn't hold out the same, no feelings of aches and pains, my body is sharper, the more the days go by, the better it is, it really makes a difference when I get up, and the next day I was used to the mattress' firm reception, I can't wait to sleep, moreover

We bought it after a memory mattress from another brand that would bother me with lumbar pain because I was digging my back, it has a rather firm support that suits me perfectly.
