Pretty solid well made firm mattress. My boy is 2 I asked him u wants a mattress that gets cool or mattress that’s bouncy. He wanted a bouncy one so I started looking for quality. This one said it weighs 25 lbs most others I was considering were 15lbs give or take. He wakes up with such great energy. He’s pretty happy to go to sleep as well. I think this was a good buy. I asked him if he likes his new bed he replies happy. So I’m telling u that’s a good thing 5 stars
