  • Great bed

    I was nervous about buying a bed online since you don't get to see the product before you buy it. But after reading many reviews and actually going to a mattress store, we decided to buy it. This bed is absolutely amazing. I have had back issues for most of my life, and after sleeping on this bed the pain has been greatly reduced. We have both noticed that not only is it easier to wake up in the mornings, we feel more rested and energized. One thing I will say though is that if you have never been on a memory foam bed, go to a mattress store to try one out first. We tried the Tempurpedic and could not tell a difference between that and the Serta, so don't be afraid if it's not the same brand. Memory foam is not for everyone, so be sure you like it before you buy one. If you know you do, then you will not regret this purchase. By the way, memory foam beds are supposed to last 20-40 years. (Much longer than a spring bed.)

  • Makes me late for work ;)

    I was a bit skeptical buying a mattress online, but I gave it a shot. My very first night on this mattress made me late for work the next morning. I really didnt wanna get out of bed. After sleeping on my old spring mattress for years, this is a breath of fresh air. I let it air out for 3 or 4 hours, and slept on it the same night it was delivered. The smell didnt bother me at all. I recommend this mattress to anyone who wants a great nights rest. Its been one year and it still makes me late for work!!

    • Please tell us about the quality of the product. Still 5 stars after one year

  • Perfect for Me

    This mattress is the best thing that has ever happened to my sleep life! After initially receiving the mattress within a week after my order was processed, the UPS guy brought the human sized box into my home for me; I opened the box, removed the plastic and the giant mattress expanded in seconds! I waited 36 hours before using the bed-even though it said 72 hours-I just couldn't hold back. That night I have never slept more sound in my life! The second night I slept in it, I awoke in the same exact position I fell asleep in. Each and every day after this I can wake up in the morning with ease as I feel completely refreshed and re-energized for the next day. I have had this product for about a month now and I can't stop bragging about it. Any other mattress from anywhere else would have been incomparable to the value I received with this purchase. The mattress itself is fairly firm which is obvious as it is only 8 inches thick but the foam makes it fell soft to the touch when you first lay down and then conforms to mold with firmness for the rest of your body. I recommend purchasing a down pillow or a memory pillow as it seemed to bother my neck with a standard pillow. Be sure to note that this product cannot be returned after removing the plastic wrapping!

  • Love

    Love it from day one. If you are transitioning from spring matress to memory foam, it is a bit of a shock the first/ secound day. It is super firm, but it molds to your body. I suffer of back pain due to herniated disks. Every day I wake up without pain. No more old person's walk in the morning. I waited 4 months before writing this review.

    • Please tell us about the quality of the product. Excellent

  • For what you pay it's great

    My partner and I couldn't afford a TempurPedic right now so we opted to try a king size Serta. The mattress was easy to unpack and came to full thickness in a few hours. The smell lasted about a week for us but dissipated after. We are both big guys and the mattress is surprisingly supportive in all sleeping positions. We have it on a box spring, as we feared it would lack the support we need on a platform. My partner has been getting the best sleep of his life after giving up his coil mattress. I sleep well but am adjusting from my Tempur. We will upgrade at some point, but it's an excellent and comfortable mattress, and a great bargain.

  • Night night everyone, I'm off to dreamland!

    We bought this very competitively priced mattress based on the reviews here. We have no regrets whatsoever at buying without trying - this mattress is superb and extremely comfortable. It looks and feel really wonderful; not too hard, not too soft. Very happy with our purchase.

  • Great mattress

    I was very impressed with this mattress. I'm a very light sleeper and I toss and turn a lot. Specially when my husband toss and turn too. But this is a thing of the past with this mattress, I cannot feel my husband and I toss a lot less. This mattress is VERY firm, so if you like soft, this is not for you! I like firm and I was a little concerns about sinking into this foam matress but this absolutely not the sace. It is very firm and it took me a couple of days to adjust. Overall I'm very satisfied and shipping was fast!!!

  • Great Purchase

    After purchasing an expensive pillow top king mattress, I found that I couldn't sleep on it. I have had back surgery and many problems back related, decided to give this a try and it's by far the best purchase I could have made. It arrived very quickly, no fumes that others have mentioned at all, so we slept on it the first night, very comfortable, no pain, no leg cramps, no pain meds. We are completely happy with this purchase.

This Serta item is manufactured by Sleep Innovations. It does not include a box spring, it is an 8 inch mattress topper. There are 141 reviews with a 4.6 star rating.
