Novilla Mattress King, 12 Inch 5-Zone Hybrid Mattress

We've had this mattress for several months now. Still no dips. Prior to this, we had a full memory foam mattress, which we loved. When it was time to replace it, we decided to try a hybrid. I'm so glad we did. We like it even better than the full memory foam. It inflated quickly, but we strictly followed instructions & didn't sleep in it for over 24hrs. I see in other reviews where people complained about the sides dipping quite a bit when sitting on the edge of the bed. That's true, the sides do dip a bit, but we don't find it to be an issue. I'm more concerned about how well we sleep on it. As far as firmness, this is definitely a medium... not firm, not medium firm, but medium. We originally wanted a more firm mattress (esp for our bad backs) & thought this one would be, but it's not. Still, it's incredibly comfortable. If I had to get another mattress, I would probably get the same type. If you HAVE to have a very firm mattress, you should probably consider something different. The only thing I could possibly complain about at this point is that the fabric cover wrinkles up & won't smooth out. It wouldn't be a problem w a thick comforter on the bed, but with a thin summertime coverlet on the bed, you can see the wrinkles of the fabric underneath. I wish there was a way to fix this, but again, I'm just happy to get a good night's sleep. As far as the smell that you get with some products, we didn't notice any smell at all with this mattress. Regarding temperature, it isn't hot like a full memory foam mattress. It's possible that the inner springs allow enough air flow to prevent a sweaty night's sleep. We waited quite a while to get a new mattress. We thought it was going to be a fairly hefty investment. Consequently, we had many miserable nights on a mattress well past its prime. I wish I had seen this one earlier. What a deal! Even if it's not your ideal mattress, I guarantee it's better than any old mattress you're currently sleeping on. For us, this mattress is perfect! Super comfortable! Not hot like our old memory foam bed. It's also much easier on our backs and joints. We wake up feeling refreshed, not like we've just spent a few hours being beaten up by our mattress. We're at the point in life now where we have bad backs, bad joints, etc. A good mattress makes a huge difference. This one is fantastic. I'll try to update again in a few more months to verify that we haven't had any problems with it and that it hasn't started sagging prematurely. So far, though, we LOVE it!
