| 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. |

Excellent! Buy it!
Style: Hybrid Medium 12"
Size: Twin
My friend wanted a new mattress. She's very picky. She loves it! I was shocked, frankly. She's tried a bunch of mattresses and hated them all. But this one she loves. Impressive! You've maybe head the story of the Princess and the Pea? Well... She's sleeping well now and very pleased. Yay!

Great for This Side Sleeper
Style: Hybrid Medium 12"
Size: Full
Love it!!!! No more hip pain. The dogs love it too! I am a side sleeper, and this feels so much better than my previous mattress. I sleep great without the pain. It is the right amount of firmness and provides good support. It does fit in my bedframe, but I got a gap filler by my headboard. I am very happy with this mattress.

High quality for the price
Very good mattress for the price. Maybe a bit on the firm side, but I am assuming it will soften up over time.

A great improvement!
I've had this mattress for two weeks, and I love it. I'm a side sleeper, and it's just right. Not too firm, and not too soft. I allowed it to fully inflate (just over 48 hours) before sleeping on it. This mattress fit my budget, has a good warranty, and suits me perfectly.

Good quality
Style: Hybrid Medium 12"
Size: King
This is very comfortable, I would give it 4 stars but they sent me the wrong size mattress and I had to set up for the old one to be picked up and tossed because it was open. Seems like a waste. Also they tried to charge me again because the pickup service didn't notify anyone it was picked up.

Got 3 weeks out of this then woke up in a moon crater!!
Style: Hybrid Medium 12"
Size: Full
UPDATED I had to come back and change my review due to mattress after 3 weeks of use. I did set up the mattress like I read. I EVEN waited 3 days before sleep on it. This mattress was great for just over 3 weeks. Then I slowly noticed in 2 to 3 days I woke up deeper and deeper in the moon crater in the center of the bed. I only weigh 139.4 lbs @ 5' 7"and had to sleep on the very edge of the mattress playing cliffhanger! Im very disappointed! I didnt have any issues at first and then it just happened so fast the mattress just failed. Im sorry Serta but OMG I never thought a company like your would fail with a good reputation with proper set up. Id SAY stay clear of this sleeptrue mattress and buy maybe a lot higher teir of Serta or Simmons. Amazon took care of me very very good with pick up and getting my refund fast to put into another mattress. I pray this new one now is worth it just over $1k. Im gonna give Serta another shot on their high teir Perfect Sleeper Ultimate 14.5" Firm Pillow Top Oasis.
