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.

  • Surprisingly great quality!
Style: Hybrid Firm 11" Size: Queen
We have two of these now, in both full size and queen. I had some concerns about the "mattress in a box" shipping method. After allowing time for the mattress to expand, you'd never know it was shipped like that. Very comfortable hybrid design, stays cool. Would buy again! The price is fantastic.

  • If you want a firm mattress at a reasonable price this one is for you!
Style: Hybrid Firm 11" Size: Queen
Best mattress I have ever owned! So comfortable. Love the firmness and keeps you cool while you sleep.

  • Nice mattress
Style: Hybrid Firm 11" Size: Twin
Very surprised that a mattress in a bag would unroll so quickly. Seems great so far. Using in a spare room so won’t get everyday wear.

  • Just unpacked first impression and nap
Style: Hybrid Firm 11" Size: Twin
Delivery service beat up box, BAD. WHOLE BOTTOM was ripped off and taped back on, in scary fashion. Was shocked that insides were intact, and vacuum seal held. Unpacked in place atop box spring. Inflates very quickly and well, no seams or dents or misshapen areas. No smells or off gassing detected, ZERO. Made bed and took a nap only a few hours later. Was exactly as described WRT firmness. This is, so far, a great buy for money. WILL update this after a month or so. ANY mattress change is likely to result in 1 to 2 weeks of soreness as your body gets used to it, so i am prepared for that, but so far ZERO complaints on feel or build quality. ... show more

  • If you want an inexpensive, soft mattress, this would be great.
Style: Hybrid Firm 11" Size: King
This was much softer than I expected, and within just a few weeks of use, the edges started to collapse (neither my husband or I is particularly large or heavy, either).

  • Very poor quality
Style: Hybrid Firm 11" Size: Queen
I ordered the first mattress and it arrived the following day. When I removed it from the box, I could see through the vacuum seal bag that there was a hole/tear (about 3"×4") in the mattress. I called to arrange a return and everything was fine. The replacement arrived two days later and I could see through the plastic there were no holes so I opened the vacuum bag. Upon removing the bag I found a grease stain on the top of the mattress. Besides the two issues mentioned, there are also tufts of fiber stuffing sticking out at the seams. These issues clearly originated in the factory and I question whether they have ANY quality control whatsoever. Additionally, the mattress is listed as a "Firm" mattress and it is not even close to firm. It is not plush but I would say it is somewhere between plush and medium firm. Overall this was a really bad purchase. The first picture is the hole in the first mattress and the second picture is the grease stain on the second mattress. ... show more

Wasn’t too sure about how this mattress would be given the price.. but WOW. It’s great. I got the firm (again cause wasn’t too sure) and it’s FIRM. no sag, no weird smells, very comfy. We waited like 24 hours to use it, and it was awesome!
