Just decided to give a review of this awesome mattress! So the wife and I bought this mattress over two years ago and we have to say that this is the best mattress we have ever bought, or slept on.
Just as a background we have owned other mattresses ranging in price from around $900 to $1300. The last mattress being a $1300 mattress from a big name company. After 1.5 years of use we could feel every spring that was in that mattress stabbing us all over our bodies. Feeling disgusted with "normal" mattresses we decided to give this one a shot, and the comfort that we have enjoyed with this mattress shadows any downfall that it may have.

Pros: 1. Can't beat the price point. 2. The most comfortable thing we have ever slept on. 3. After two years the memory foam still has no dents, it returns to its original shape each and every time. 4. It does not have springs!

So like a said, the comfort outweighs any downfall, but there are a few valid ones that are in other reviews also.

Cons: 1. This mattress is a tank! You better have a gorilla in the closet to wrestle this thing to its resting place, and when you need to rotate it. We haven't felt a need to rotate it, but we still do just because. 2. The chemical smell when you first punchure the package and roll out the mattress is really bad, I think the smell lasted around 1 month before going away completely, but it does go away! 3. The mattress is extremely firm for I would say around a couple weeks to 1 month, but after that it is like a dream!

I would suggest that everyone who has purchased one of these mattresses to take the time to unzip the cover and look at the foam layers included. I ordered two 12" XL Twins for our use at home with a new split-king adjustable bed sourced elsewhere. The mattresses delivered to our home are far different from those described in this offer. Instead of four distinct layers of foams, ours have only rwo. Our mattresses DO NOT INCLUDE the "two 2" state of the art foam layers". Instead we got 3" of blue foam (assumed to be gel) and 9" of base foam. The nine inch layer does have some cut outs that look like they are intended to assist the mattress if intended for use on an adjustable bed. None the less, we are dissapointed to discover this obvious attempt to defraud us with a substantially different product than the one ordered. So far attempts to reach Dynasty for resolution have fallen on deaf ears. Buyer beware!!!!

This product is horrible. The mattress has not held up. My wife and I sleep in "troughs" every night. I have tried to contact the company but no one answers of returns calls. I filed a return request and Dynasty Mattress rejected it because of the amount of time I have owned the mattress. I did not expect them to return it, I just wanted to see if they would communicate with me. I cannot recommend this mattress because it will not hold up. I have purchased a queen for another RV that we owned and a full size 4.5" model for our hide-a-bed and they seem to hold up pretty good. Our King mattress has been garbage and will have to be replaced at my expense. So much for a 30 Year Limited Warranty. I have found their warranty is not worth the paper it is written on.

Edit: The company has contacted me via e-mail. I have been exchanging e-mails with them for most of the day. They have been requesting pictures of the mattress and I have been obliging them. I am posting a few of the pictures I have taken and sent to DynastyMattress.

Edit # 2: I heard back from DynastyMattress sales and they are replacing my mattress based on their warranty specs. I have to pay 120.00 dollar shipping charge for the new mattress, which I am not entirely thrilled about but I understood that when I originally purchased the mattress. I must say that once I communicated with them through their e-mail address the communication was satisfactory. We enjoyed the comfort of the mattress until it began to compress, so we are excited to replace it with a new one- let us hope the new lasts.

Edit #3: I received my new mattress as promised. kudos to Dynasty Mattress for standing behind their product.

Had it for 2 years and LOVE IT! We DID wonder WHY there was a hump in the middle that just didn't seem to go away, and today I decided to find out why, and lifted it to flip up, and discovered that it CAME WITH TWO PILLOWS WE NEVER KNEW WERE THERE!! They had partially expanded, and were causing the hump!

Other than that, we love the firmness, and have witnesses NO CHANGE in the mattress after having owned it for two years. It keeps ius cool at night, and was the ONLY way I could get comfortable when I broke a few ribs riding a bike earlier this year. Love it and would absolutely purchase it again.

So, my old spring mattress was giving me horrendous back pain and I had enough of it. My wife and I decided to pull the trigger on a new mattress so I started searching on amazon. I heard good things about Casper and wanted something similar. A friend told me he had a dynasty mattress and loved it. He claimed that for the first month it was a bit firm, but eased after a break in period and he always woke up refreshed.

We decided that the Dynasty Mattress sounded good especially for the price. It arrived in a tall, slender box that was delivered to the door. After cutting the box open, the mattress immediately started to unfold itself and inflate. The pillows that came with it were a nice addition and they inflated as well. I was aware from reading the reviews of the "chemical smell" which IMO is overblown. I just set the mattress out by the door and let it air out for a few hours. I didn't notice any strong smell and slept comfortably.

So, it's been about 2 weeks and my back pain is gone and I sleep like a baby. Loving it so far!
