Product Care Instructions: In order to protect your mattress from stains and spills, we recommend using a mattress protector. 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.

  • Comfortable sleep
Style: 15" Plush Pillow Top Size: Queen
Very comfortable. Just what I wanted. Soft enough for those achy spots on the hips, but firm enough for back sleeping as well. Would absolutely purchase again, if needed.

  • That it’s not a true king size mattress
Style: 15" Plush Pillow Top Size: King
This is not a true king size mattress. It’s an RV mattress. It’s smaller than a regular king but bigger than a queen. Misleading on information page

  • No.
Style: 15" Plush Pillow Top Size: Queen
For almost 900 bucks I thought a plush pillow top would actually have a plush pillow top. And it’s supposed to have cooling technology but I’m up at 3 in the morning. I’m hot and very disappointed in my new mattress.

  • Very misleading
Style: 15" Plush Pillow Top Size: King
Very disappointing purchase. The plush pillow top might as well be labeled “firm 15” pad”. There’s no softness to this bed - it’s far more firm than any mattress I’ve used. Value and quality for this product does not line up. You’re better off getting something a few hundred dollars less that’ll be more comfortable. There’s nothing resembling cooling properties. Movement isolation is nonexistent. If you’re looking for something firm, I’d recommend the “plush pillow top.” It’s anything but. ... show more

Comfortable and solid. I wanted a brand name I could trust but wanted a great price. Amazon Day sale seemed like a deal. Excellent delivery. Great mattress for my extra bedrooms.
