This will also help with the overall health and lifespan of your mattress., To clean your mattress, we suggest applying baking soda to the soiled area and letting it stand for about 15 minutes. 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.

  • Wonderful
Style: Hybrid Firm 11" Size: Queen
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!

Style: Hybrid Medium 12" Size: King
The most comfortable bed I have ever slept on worth the money!

  • Firrmness
Style: Memory Foam Firm 12" Size: Queen
Nice mattress but I think you need to have a box spring, too low for just platform, no issues opening it and it’s nice and firm, using for guest room

  • Do not recommend
Style: Hybrid Medium 12" Size: Queen
Worst mattress I’ve ever had I do not recommend buying mattresses from a box. I’d say just invest in a good quality mattress! Don’t go the cheap route like I did because your quality of sleep will pay for it! Already started flattening out on the bottom only after having it for a few months!

  • 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

  • Broken box
Style: Hybrid Medium 12" Size: Queen
Received the item in unsecured box. Meaning, the box was open and broken. But the item is still intact. The quality of the mattress is somehow on the softer side, not medium and it looks small for a queen. I'm thinking if I should return this.
