Serta Perfect Sleeper Midsummer Nights

Ordered this mattress in a King and a Queen. I expected both to be exactly the same but they're not. The King is FIRM and has stayed firm since delivery. The Queen feels SOFT like something is wrong with it. I've slept on both and am really wondering why the same mattress in different sizes are so different.

Nurture night plush mattress

Well….. definitely would of been a 5…. But here are a few points that made it a 3 Only had this for a couple nights so hopefully it will get better. Definitely different levels of plush …. To me, it is a light medium firm. It is not plush to where it feels like a cloud. It is a durable and thick mattress. I was hoping it would be a better mattress for a side sleeper. In hopes it gets better.

Love my new Serta!

I am happy to have purchased the Nuture Night firm mattress. It’s just firm enough without being too hard and I feel like it supports my body well. So far I’ve slept very well on it. I would recommend!

Sadly disappointed

Divots formed within days. The support is non-existent. I wanted to love it but I wake up in pain. The edges dip immediately when under pressure for more than five minutes.
