    This is very comfortable and firm. We were able to sleep on it within about 8 hours but did find that it continued to expand a little over the next 24 or so hours. It does not have a funny smell like some of the memory foam mattresses. I am very pleased with this purchase and considering buying one for our guest room.

    We purchased this mattress to fit our water bed frame. Was concerned with the fact it comes shrink wrapped but no worries now! It arrived and we immediately opened it and put it in the frame and it fit perfectly. Placed clean sheets on it and never had a packaged smell to the mattress. Slept on it the same night and have slept great ever since. Would definitely recommend this product. I've had other memory foam type mattresses that were hard as a rock. This one is firm but not rock hard. Perfect for us and our backs and legs.

    Just got the bed yesterday. Opened it up on the floor and it quickly filled out, No funny smell, not very heavy (our old Simmons was HEAVY and not a memory foam.) It feels great. We're in our 60s and each have sore spots we sleep around. I slept great, woke up great. It's 10 am and he's still in there sleeping. I guess he likes it! The Cal King sheets we had fit this bed better than the last because we had to put a mem foam topper on it to make it sleepable. This is just nice all by itself. Waiting for the sheets.

    My husband and I were a little skeptical about purchasing a memory foam mattress, especially for the price it was being advertised for. Needless to say, we were 100% satisfied with this purchase. My mornings of waking up with lower back pain are over. The quality of this mattress exceeds the asking price.

    But overstock sucks when it comes to shipping. They literally take like 10 days to even ship orders, and then almost another 10 to get it to you. Too slow to even wanna get a discount. Also, when we ordered this bad we weren't even aware that the CA fires were slowing down the shipping process AT ALL.. there was no notice on their website or an email.. mind you the fires were about a month ago so not even on our mind.. anyway we sent them an email and that's when we found out there was a delay due to the fires. I would have liked to know before ordering. I would not have ordered it from them had I been made aware. I guess that's why they aren't upfront about situations like this.

    We were hesitant about this, just because of the price I guess?! All of our friends/family go to a local Mattress Firm or Sleep Train sort of thing and spend *** on a new bed so we thought we were crazy for spending only *** on this. But, we've slept on it for a week now and we LOVE IT. Much more support than I thought, very comfortable, and although it is 105 here during the day and about 75 at night, this mattress stays cool. Would buy again! VERY HAPPY!

    I was the not-so proud owner of an old cal-King water bed. I decided to put it to use with a foam matress. Not only does this fit, I was able to use the old rail caps, matress pad and sheets. It's comfortable from day 1 and, unlike other foam mattresses, it doesn't make me sweat.

    i recommend this mattress if you like firm support. It's my second one by Sleep Innovations (went from a queen to a cal king which my best friend now loves too)! An extremely reasonable price, but I choose it again based on my past experience. I love it. Look forward to it every night.

    The mattress arrived earlier than scheduled and was very easy to unpack and lay on the platform. There was no smell whatsoever and it was ready to sleep on within 6 hours. So far, the mattress is great.

    I had back surgery a year prior to purchasing this bed. I only regret not buying it a year ago. The remainder of my low back stiffness from surgery was gone in week! I feel great. All pressure point soreness from sleeping at night is gone. I stayed at an Air B&B that had this bed and that prompted me to buy it. I also saved a lot of cash buying it on Over Stock.

    We like it so much we bought a second one for our guest bedroom. We've used one of these mattresses for the last 10+ years and absolutely love it. I was tempted to try one of there newer models that are 14" but not for 4x the cost.

Questions & Answers

  • Q:

    "Can you place this mattress on a regular box spring or does it require a different platform?"

    • A:

      The mattress can be placed on a box spring. We do not recommend placing it on a solid platform. The form needs air to “breath”

  • Q:

    "I noticed the question I wanted to ask was asked already but not answered. How is this mattress for someone that weighs 200-215 ?I have a Serta Cal-King pillowtop that after three months it was sunken in and has left a hole where I sleep. It is killing my back !! I need to know that this will NOT happen with this mattress. We paid $ 1800.00 for the Serta and it SUCKS !!"

    • A:

      We've had this mattress for 2 1/2 months now, my husband weighs 220 and it is still just as firm as the day we got it

  • Q:

    "Why did you choose this product?"

    • A:

      We also have a waterbed frame and your reviews are excellent for this type of frame; also, the fact that one of the reviews mentioned that you don't sweat with this product. I am really looking forward to trying out this item.

    • A:

      I spent hours attempting to read reviews and compare options when transitioning from traditional mattress to a memory foam mattress. This mattress had very good reviews and at an excellent price-point and decided to stop reading and start living! I am hoping this meets expectations.

    • A:

      Was on clearance
