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.

Style: Hybrid Medium 12" Size: Queen
I could take a picture but I believe my statement will speak louder this is the best mattress that I have slept on in years. We normally change our mattress every 5 to 6 years or less and searching Amazon and the variety of stores in the Tulsa County area to no avail over the last 3 months. This mattress is one of the best it is totally comfortable firm yet not firm plush yet not plush soft yet not soft if you need a good mattress and a really really really good night's rest this is the one to buy! ... show more

  • This really is a great mattress for the price
Style: Hybrid Medium 12" Size: Full
This mattress is so worth the money! I'm very happy with the purchase of this Sleeptrue Hybrid. I've been sleeping on it now 4 nights and it's so much better from my 4 year old Simmons Beauty Rest that was almost double the price. It is definitely medium firmness just perfect not overly soft or to firm. There wasn't a powerful smell once unsealed it aired out pretty quick. I built the Lifezone bed frame and expanded the mattress on it. The manufacturer date was just under 4 months to when I opened it. So it wasn't boxed up to long so that shows I feel they're selling well. The high returns it shows for this mattress I dont get why. When I unpacked the mattress I let it sit 12 hours. Then crawled all over the top back and forth if there was any foam cells that needed help to open. I first slept on it after 26 hours and what a good feeling bed. I was skeptical about the no box spring it says being it does have springs. The Lifezone frame specifies it's made for this type of mattress. This mattress has lived up to the counting sheeps on the box. ... show more

  • Comfortable
Style: Hybrid Medium 12" Size: Full
We bought this bed to move my toddler into his first big boy bed. Great quality, extremely comfortable and perfect for when mom or dad end up falling asleep in there as well lol. True to size and will last us many years to come.

Style: Hybrid Medium 12" Size: Queen
Very good mattress for the price. Maybe a bit on the firm side, but I am assuming it will soften up over time.

  • 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.

  • Sweet Dreams
Style: Hybrid Medium 12" Size: Queen
Frustrated by the fluff of mattress store sales tactics, so I looked at AMZ & found this dream mattress!! Goldilocks approved... #justright Order & delivery were a cinch - UPS driver did the heavy lifting. Mattress is packaged well in a tiny box. Make sure you have plenty of space for opening the box & removing the packaging!! Air out for 2-3 days, cover with normal bedding, and enjoy your first good night's sleep. You won't want to leave the bed! 12" is the perfect size & the hybrid construction offers unbelievable comfort. Regular-queen linens fit perfectly. Mattress-in-a-Box is a strange concept till you realize how much sense it makes. Cut out the 'middle-man' and order directly from AMZ Prime. Serta is a classic brand for a reason - hi-quality product for a fair price & years of construction experience. ... show more
