Style: Level 3 Medium 10" Size: Twin
Great sturdy but still soft mattress. We opened it and let it settle for 2 days before putting it on the bed. My kid says it’s very comfortable and has slept like a champ.

    • Too short, not the normal twin size
Style: Level 2 Medium 8" Size: Twin
This mattress is only 71" long, and the description says it is 74" long. It is unusually short, and it is super disappointing. We always buy Serta, but this mattress is defective. DO NOT buy this mattress. The cheaper brands would be better so that they would at least fit the bed frame. Very disappointing. ... show more

    • Size is not big enough
Style: Level 3 Plush 10" Size: Full
My bed is a full size. I measured everything before I bought. This mattress is about 2 inches smaller than it should be all the way around. It is a great mattress but I have to buy wedges to get it to fit.

    • Amazing mattress!
Style: Level 3 Plush 10" Size: Queen
This mattress is amazing. You can trust serta. Previous to this one I had a serta perfect sleeper mattress which was used for over 10 years. It became too soft but it lasted a long time. Now this one gives me the support my back needs. I was worried the plush mattress would be too soft and not offer support but it is perfect. If you lay flat on it it gives great support and is not hard. I sleep great now. If you want a mattress that isn't too firm but offers support, this is a great choice. It does have a light smell, just like any new mattress would, but once you put sheets on it you can't smell it. And I'm sure the smell eventually goes away. ... show more
