Then, vacuum and repeat as needed. It's important that you also air the product out as much as possible., We do not recommend applying liquids to the product. Applying liquids may stain the fabric and could potentially make the soiled area worse. Moisture or chemicals applied directly to the mattress can cause premature breakdown of the foam and damage the product.

  • Worth the purchase
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.

  • 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

  • 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

  • Runs few inches shorter than advertised size.
Style: Level 3 Medium 10" Size: Full
It runs shorter than advertised size, leaving about few inches gap from the mattress frame. I purchased medium firm and felt softer than it supposed to be, pretty comfortable though. Quality wasn’t bad at all considering the price, the only issue is the sizing.

  • This feels sooo good ! Your back might need this !
Style: Level 3 Medium 10" Size: Twin
I took a chance and ordered a mattress on amazon... Serta.. good quality brand I know well.. I have now spent exactly 1 night on this mattress so take it for what its worth. * insert happy dance here* My bad back is ecstatically happy ! Awoke with no pain and that feels soooooooo good. The bed in a box was new to me so I was bit nervous about the vacuum seal thing but it was so easy that this 75year old was able to do it alone. I did need some help with the putting it on the bed part but that's why God invented grandsons! Very comfortable , perfect firmness and has the total approval of the dogs. ... show more
