It's sufficient for my purposes. I'm 220lbs and sleep on this, plus a 3" Tempur topper, on slats until I can afford a proper matt./box set. No issues so far. It's comfortable. I'm sure the extra 3" helps, though. It's heavy as heck, so don't like moving it around too much or trying to get under it.

It’s definitely soft and very comfortable for kids. Love that it comes with its own mattress protector.

Pretty firm but fits our needs perfectly. Bought this for an autistic toddler’s first twin bed and did not want her being able to jump on her mattress and get hurt - she sensory seeks a lot. This has been great for her.

This mattress served its purpose. More comfortable probably for child through young adult.

This is very comfortable! I just wish it was thicker, I bought another mattress pad so now I sleep on a cloud!

I waited a few months after purchase to review it to make sure I could get the feel for it. We use it on my son’s loft bed and while he does love it, he says sometimes it sinks in a bit too much. It’s comfy and not too thin, but it does compress quite a lot which can cause it to not be as plush. More like a soft firm bed rather than a firm bed. Still great though and it works well.
