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.

  • Nice mattress
Style: Level 2 Medium 8" Size: Twin
Very nice very comfortable, surprised at its quality especially for the money. It’s definitely a future buy for any other single beds that I need to change out mattresses for.

  • Nice, but possible size issues.
Style: Level 2 Medium 8" Size: Twin
First impressions, we opened this mattress about an hour ago. It seems well made. We typically like and seek to buy Serta. It did start expanding immediately after opening. So far, after about an hour, it has expanded to about 5.5" (we purchased an 8"). I believe it will fluff a bit more, but not sure if it'll make the full 8". Here's the real downer though; a twin mattress is supposed to be around 75" in length. This mattress measures at about 71.5" leaving quite a lot of gap at the top and bottom. I do not believe that the length is going to fill out. This is very disappointing in regard to the overall fit. I checked the twin xl and the price is around $100 more (supposed to be 80"). The conundrum is, would a Serta twin xl be less than the stated length and therefore fit, or will it be true to size, and be too long? ... show more

  • Overrated
Style: Level 3 Plush 12" Size: Twin XL
It seemed to be made decently. However, when it was delivered the box seemed and was like it ran the marathon. On top of that and most importantly it stated plush top. My wife felt it was quite hard and uncomfortable. Nevertheless we returned it.

  • Comfortable Mattress Bought
Style: Level 3 Plush 12" Size: Queen
It's as comfortable as advertised and good for the price. It was a bit heavy to get up the stairs but that's normal for a mattress, once it was up there it was easy to set up. Just make sure you let it rise for the recommended time before using it.

  • Not plush! More firm and can feel springs.

Not plush! Could feel the springs by just pushing down with my hand.

  • Good quality, good sleep
Style: Level 3 Medium 10" Size: Queen
It was still a little more firm than I expected but a foam topper solved that and it's very comfortable
