    The Choose Your Comfort King-size Mattress gives you 12 inches of supreme, lavish coziness. With this mattress, you will get even more options to customize your mattress. Choose from three (3) support preferences to fit your individual needs: soft, medium, and firm.   Every layer is engineered to work symbiotically with your body's needs. It's filled with gel for extra support and refreshing airflow. Since memory foam removes pressure points, aligns your body, and revolutionizes sleep, it's a personal experience. The mattress ships to you in a resilient protective sleeve so you don't have to worry about damage.

    • Soft not so soft
      Verified Purchase

      I've been sleeping on the King Size soft for about 2 weeks now and it's not as soft as I was hoping. I'm a side sleeper and my shoulders hurt so bad. My problem is there is no label on the Mattress itself saying the brand or comfort level. The shipping label said ss King soft but the Mattress itself didn't have anything on it. So how are we supposed to know that the comfort level we ordered is what we got? I have read other reviews about some people that were unsure if what they got is what they ordered. My soft feels like a medium. I weigh 170 and it hardly sinks in. But there is no way to tell if I accidentally got a medium or a firm instead.

      inwould recommend this mattress for this price to anyone. It beats out last mattress by a long shot. I wake up happy and fall Asleep happy. I didn't rate it five stars because it's not as flexible as I would like:

      I was a little worried about buying a mattress online but this is an awesome mattress! It is very comfortable my body relaxes as soon as I lay down on it! It was easy to get up the stairs and into our bedroom instead of trying to maneuver a big king size mattress.

    • Excellent bed
      Verified Purchase

      This is a great bed. I am a very cautious buyer. I shop and shop until I find what I hope will be the best. The delivery was a little late but no big deal. We did open it as soon as my husband and I got it. We aired it out for a couple of days. No odor though like other people have experienced but we did it anyway. It was really cool how it came though. Vacuumed packed. It made it easier to manuver around. But look out when you cut the vacuum packed raping. It expands quick. Anyway, my husband and I LOVE it. We have another memory foam queen size bed in our spare room but it doesn't have the gel in it so in the summer it gets kind of warm. But overall, we appsolutely love it. Firmer than I'm used to but I think it's going to be better for me for my back. My husband loves it too for the support. The first night we slept on it he never woke one time during the night. Our cat Gizzy, he loves it too. Great bed, I'm very glad I took my time to find it and finally buy it. I will recommend it for sure.

    • Heaven!

      We were a bit hesitant about ordering a mattress online but we are so glad we took the risk! We ordered the soft and enjoy every second that we get to lay in it! I'm 8 months preggers and have had a sore back since about 4 months in and ever since night 1 on this been my back has felt great! Ours was not smelly at all either and doesn't sleep any hotter than a spring mattress.

      I have very high expectations. I knew that because I only spent about XXX bucks on this mattress that it wouldn't be comparable to some that I've tried in stores at triple the price. I was wrong. It does compare and it is a great mattress. Don't be fooled by the state the mattress comes delivered. After following the directions and letting it air for 48 hours, this mattress is amazing for the price. I'm hoping it lasts a few years. Very impressed! If you like somewhat firm but not hard, the medium is what I ordered and it is great..

    • Slumber Solutions Gel Memory Foam Mattress
      Verified Purchase

      I love this mattress! We had a pillow top firm traditional mattress for 17 years prior to this one. I woke up in pain every day. I have arthritis and it was painful to start the day. Now I wake up pain free. I had purchased a queen size memory foam mattress from Overstock for our RV and was very impressed with it also. So took the chance and ordered one for our home bed, and I don't regret it at all ! We live in a region of California that is very hot in the summer. My only concern is that it may be too hot in the summer. It seems to hold body heat. Over all.... very satisfied. And can't beat the price compared to traditional mattress sets that can be into the thousands of dollars.

    • REALLY happy with my purchase!
      Verified Purchase

      I bought this mattress back in February but wanted to give it some time before I gave my opinion it. We decided on the medium firmness after reading all the reviews. Both my husband and myself were having some back issues with our old mattress and now neither of us have any of the aches that we had prior to sleeping on this mattress. The mattresses firmness isn't an issue for us but I suggest a bigger pillow of side sleepers. I was also afraid that this mattress was going to make us sweat but it isn't any worse than our old one. We are extremely happy with this mattress and have in fact suggested it to a couple of our friends who have bad backs because for the price you absolutely cannot beat it!

    Questions & Answers

    • Q:

      "According to the item description, all three mattresses (soft, medium and firm) have the same composition of gel memory, polyurethane, and supportive foam base: 3", 3", and 6". They also only state one foam density, 3.5. So what makes this soft, medium, or firm? Any recommendations on which is "better" if I'm looking for a soft mattress but don't want to "sink 8 inches" as one other buyer has said they did?"

      • A:

        If they are sinking 8 inches, then they must be an extremely heavy person. This is the most comfortable mattress we have ever had. My husband is a big guy, almost 300lbs, and he doesn't sink. I would HIGHLY recommend this mattress to anyone who is needing a good nights sleep.

      • A:

        This mattress is awesome. I can't feel my husband move at all on this mattress. I have had memory foam mattress before and this one tops it. I have slept better on this one. I have not experienced sinking at all even when just sitting on the bed. You can't go wrong with this.

      • A:

        Medium is definitely soft but also provides support. Hope this helps

      • A:

        I have the soft version, and I do not sink. It is still firm, and very comfortable.

    • Q:

      "Can I purchase now, to be delivered in 2-3 weeks so I can be inside the 72 hour unwrap window?"

      • A:

        Was shipped in less than one week from purchase date. It was really fast shipping! Especially for something that is 100 lbs!

      • A:

        Tip when letting your mattress air out for 72 hours: open it in the room that you plan to use it in. I opened it to air out and then had to haul it up 15 stairs to the second floor! It's a lot easier to carry up stairs while still in the packaging and then take it out in the room or floor you plan to use it on

    • Q:

      "Product dimensions Length: 83 1/8 " Width: 82 1/4 " Footboard height: 15 " Headboard height: 39 3/8 " Mattress length: 79 1/2 " Mattress width: 76 " This is the bedframe I currently have, says the mattress is 80" long. For my frame it says the mattress should be 79 1/2" so I get it, need half an inch more. Question I have is do you guys think it'll fit still? Since it's foam and it can probably be "played" with a little?"

      • A:

        My best guess is yes, it will fit. It's pliable and I can push the sides in a little with my hand. Might make it a little tight changing your sheets, though!😊

      • A:

        We agree with anniem's answer. Should be okay

    • Q:

      "Is there a maximum weight limit for the 12" king?"

    • Q:

      "If you use a heated mattress pad during the winter months will this affect the gel memory foam in any way?"

    • Q:

    • Q:

      • A:

        No. It is a great mattress though :)

      • A:

        It does have a zipper on it so I guess you could remove it. Not sure how hard it would be to get it on and off though. We keep a waterproof mattress pad on it and haven't had any issues. We love the mattress.
