I have had this 8” mod mattress for a year and a half now. I absolutely love it! I have never had another mattress I’ve liked better. I used to buy $1000+ mattresses from mattress firm and other stores. This was my first time ordering a “bed in a box.” I ordered a couple different ones off amazon and liked this one the best. Amazon was great with retuning the others that didn’t work. I got the king size nod and it is true to size and height. When you first get it, it takes a while to expand to it’s full size. After a year and a half it is as good as new and still feels and looks the same. There’s NO weird indentions or what my husband and I jokingly call “ditches” lol. In other words the original form is in no way compromised after using it every night for a year and a half. Both my husband and I love it. It’s a medium firmness in my opinion. My husband likes a soft bed and I like a firm bed, this was a happy medium. When you lay down it has a little give, but not too much. I have horrible back problems and I sleep so much better on this mattress than I have on any $1000+ serta or what have you. Once upon a time I had a tempurpedic, it was way too hot! This Nod mattress is NOT hot in my experience. Even when I was pregnant and had hormonal sweating this did not make me hot. I’m a very hot natured person too so it’s very important to me that my mattress doesn’t add to that problem! With other memory foam mattresses I’ve had, I had to even change clothes during the night, not fun!! I definitely think the comfort and quality of this mattress is comparable to other high quality expensive memory foam mattresses, if not better! Like I mentioned I had to give away the tempurpedic (spelling?) due to it being way too hot! I would highly recommend this mattress to anyone really. I think it accommodates a lot of people due to its adaptive nature and medium feel. I think a medium firmness suits many different people and situations. It’s definitely not in any way a hard bed so if you are used to a soft bed, don’t let the word medium firmness scare you! I can sleep on a more firm bed (due to my back issues) but this works fine for me even though it’s a little softer! I am a stomach sleeper and my husband is a side and back sleeper. It works well for both of us. He is 220lbs and I am 130lbs and we both love it. It’s not easy to find a good bed for a stomach sleeper but this one is a winner! I would definitely recommend this to pregnant ladies, or hot sleepers as well! I also think this would work great for a child, toddler or guest bedroom as well. It’s sure to suit any guest who would come to stay over! Our kids love the bed as well. We eventually are going to order nod beds for their rooms.Oh and also if anyone was wondering I 100% purchased this mattress with MY OWN money and no I am not getting paid for this review or any other type or compensation! This is an honest review of someone who spent their hard earned money on this bed! My father is actually buying one for himself for Christmas because he loves our bed so much! He has lupus and is in the market for a bed that will make him very comfortable!Good luck and remember if it doesn’t work out amazon prime is really easy to return it! Just leave the bed outside your door and they come and get it! I hope my review was helpful to someone out there. I know ordering a bed online is hard. Look up some YouTube reviews, they really help!
