  • love our new mattress

    Me and my husband received our mattress about a month ago and absolutely love it! I don't think I have ever slept so good! It shipped quickly and paid less than we would at any furniture store!

  • GREAT BUY

    I ordered the bed on Monday got it on Thursday (FAST). Opened it up and allowed for it to recover its correct size 72 hrs. Much longer than needed I am sure, had expanded to its 12 inches in just a few hours. Hand almost no smell. The bed is supper comfortable and as of now I feel it is the best bed I have ever bought. I do recommend this product.

  • Great mattress...a little too firm

    This mattress is great. It arrived in 5 days after ordering it. It is the perfect height for our platform bed without a box spring. It has a lot of support but is a bit too firm. It's hard to buy a mattress online without testing it first! I thought the memory foam might soften up a little after a while but it didn't so we went ahead and bought a cheap memory foam mattress topper and put that on which made the mattress perfect. There is a lot of support from the mattress and the pad on top adds the perfect amount of cushion. Considering you can buy the same mattress on Amazon for **** more, I think this was a great deal and would absolutely recommend it.

  • DONT do it.

    Don't do it. It is comfortable for a year and then you sleep in a dip and struggle to get out of bed in the AM. The foam just stops bouncing back. Two of us sleep on the bed and we way 175 and 130 pounds each. i am so disappointed that today I have to go buy another king sized mattress WITH SPRINGS this time. I will never buy another FOAM mattress again.

  • Soft yet firm

    This memory foam mattress molds to your body shape making it soft, yet it is still a firm mattress. I had a great night sleep on it and did not want to get out of bed. A great product that was shipped in a small box. I was confused as it was not mattress shaped. It was vacuum packed. I wish I had videoed it unfolding when I cut the bag.

  • Love it, Love it Love it!!

    After reading the reviews we were ready to wait 72 hours before sleeping on this mattress but not so. We unpacked it, placed it our new King Size Bed and it rose into shape immediately. We slept on that new mattress the very day it was delivered.

  • Great deal for a nice bed

    We purchased this bed to replace a worn out cheap inner spring mattress with a large hole in the middle. This bed arrived on time, actually a day ahead of schedule. Once we had the bed set up and sheets on it, I laid on it to see how much of a smell it had. Honestly, I could only smell it if I laid face down on the bed. Even then it wasn't too bad. We set it up on a Saturday morning and slept on it that night. It was soo much more comfortable that the old mattress. It doesn't carry motion from one side to the other, it doesn't bounce when you jump on it, if doesn't cause my shoulder to hurt like the other mattress did either. It may be a bit warmer than my old mattress, but not by much, and certainly not enough so to make me uncomfortable at night. Now I will say it is firm, and I like firm mattresses. My wife and I sleep fine on it, but we will be getting a padded mattress pad to protect it and add a little softness to it. Otherwise it is a great deal on comfortable bed.

  • Much firmer than I expected!

    After sleeping on a mattress that was way too soft for years, we decided to buy one that was firmer. This mattress is very solid once it opens. It gives a little, but it's still much firmer than I expected. We will need to get a topper to soften it a little. It has good support and it's a great base, but I want a little more give on the top. It does not transfer motion and I can't even tell when my husband rolls over or gets out of bed. I was pleased to see that it was manufactured in the town I live in. Delivery was super fast.

how does this mattress compare to the Serta Pierta gel memory foam queen size mattress in terms of firmness beeno01 on Jun 12, 2014

Answer This Question

Thank you for the question beeno01. I am sorry but we do not have the information to compare the two mattresses together. This particular mattress has received very favorable reviews. I looked on other sites and can say that the Pierta also got favorable reviews especially when talking about heat dissipation. I am sorry I couldn't answer the question.

Hello jjbittinger, this is 104 pounds. Have a great day! overstockcustomercare1 on Jan 14, 2014
 
I do not know the exact weight but I can tell you that the average size person isn't going to be moving it alone. I can't move it even an inch. But that is one of the reasons I wanted it. Our previous mattress was like sleeping on a trampoline. luvdasea on Jan 24, 2014

Hello golfingjays, we currently do not have any reviews on this item so there is no way for me to see any complaints. I just got my first memory foam mattress last month it also is a serta and it had no smell at all. These beds are so comfortable! Have a great day! overstockcustomercare1 on Dec 19, 2013
 
We did not notice too much of an odor at all. Guess we were lucky. blinkon2 on Feb 28, 2014
 
 

how come this has no reviews? I'm trying to see if this one is similar or as good as the 8-inch Serta Memory Foam Mattress. eliast on Nov 27, 2013

Answer This Question

Hello eliast, This is a new item so there are no reviews yet. From my experience with memory foam I think this one would be better than the 8 inch because it has Three foam layers where the other one only has 2. Happy shopping! overstockcustomercare1 on Nov 29, 2013
 
We got the 12. Very firm, we do like it and would buy it again, but it could be a little softer. blinkon2 on Feb 28, 2014
