    • Best foam mattress next to Tempurpedic
Size: Full Style: Extra Firm
This mattress is hands down the best bed I have ever had. I have severe degenerative disk disease and other degenerative health issues that cause constant pain and I need a firm mattress that offers support while still cradling my body. I had resigned myself to suffering with sub-par foam beds until I could afford a Tempurpedic. This mattress changed all that! I ordered a full size extra firm because last time I ordered a foam bed from a different retailer it was a firm but right out of the box it slept like a medium and broke down to a plush very fast. This mattress is indeed EXTRA FIRM. The top foam layer has very little give, but it's just enough to offer me comfort. If you've never had a foam mattress before there are some things to know. First, give it a full 24 hours to expand before sleeping on it. Second, order one level firmer than you need. Foam mattresses soften over time and tend to become one level softer than their out of the box firmness. Once the bed has expanded, step on the bed all over to help break in and degass the mattress. This will soften the top layer so it cradles the body more efficiently. I am thrilled with this bed and am looking forward to lots of restful nights. Thanks Dynasty!!!! ... show more

    • Absolutely abhorrent customer service. I really wanted to love this mattress...
Size: California King Style: Extra Firm
...and maybe I would have, if we had actually been able to exchange it for the right firmness. This item is advertised as returnable, so my husband and I took a chance on this unknown brand. He has back problems and I am pregnant so we ordered based on the firmness of the last good mattress we had from another brand. Big mistake. This bed is hard as a rock. My husband's back pain has worsened to the point of being unable to sleep and waking up sore every single day, and I struggle with side sleeping (a necessity during pregnancy) due to aching hips, ribs, and shoulders. So after giving it a solid try for a couple months, we couldn't take it any more and messaged the seller to exchange or return. Well, there's the kicker - they expect the customer to somehow vacuum seal and pack the mattress to be shipped!! How?! Any reputable mattress brand has pick up services. I am now 1 month from my due date and have been trying to get this thing returned for MONTHS. We paid over $700!! This is the last thing I want to be worrying about right now! Maybe the softer firmness would have worked for us, but after this experience I am unwilling to use this company any more. This thing is now just taking up space in the room I am supposed to be decorating as a nursery. I am so beyond furious. I would NOT order from this company unless you have physically tried out the mattress beforehand- and probably not even then because what if it arrives damaged from shipping?? My husband and I will be paying the couple hundred more to go with a reliable company instead- so worth it. ... show more

    • Poor quality control !!! Wrong again
This is the most frustrating item ever have purchased. We ordered the dynasty mattress king firm .. the 1st one arrives quickly yay and it is a firm yet .that is where the positive stop , wrong measurements doesn’t fit my king sheets nor my king bed frame odd size . Contact Dynasty customer service ugh sent pictures showing wrong size . No word from them but Amazon did send a replacement and it too arrived quickly but .. it isn’t a firm it isn’t a 80 X 76 it is close but so soft it is Not comfortable it could be even dangerous the sides have no zero stability.. like flat pancakes soft . the box on both say king Firm yet the first one was very firm which is great however the measurements are completely off The second one the measurements are very close to what it says on the box however this is not a firm mattress !!!! It is not even a medium mattress I ordered this brand mattress specifically because I had ordered a RV king mattress it is fabulous it is wonderful I love it !!that is why I went with this company after waiting two years to make a decision to get one for home this is the most frustrating experience I’ve had we expect to get what we pay for ! we don’t want mattresses piling up ..there is no way to give these mattresses away no one will take mattresses today even new ones that you show came out of a box with the plastic underneath because of health concerns, so we have to just store until we can get it picked up hopefully go to somebody wants one for free but we still don’t have what we paid for I want my king size firm mattress .. The quality control from this company is beginning to be more questionable than I initially thought I don’t understand how A company can make mattresses and not have some good form of quality control to ensure that the size and order is correct that goes out what you put out says a lot about your company !!!customers today expect to get what we pay for I want a king size 80 x 76 mattress firm that is what I’ve paid for !! someone needs to correct this issue and at this point I don’t want to give this any stars because this experience is so frustrating I simply want it to be corrected I want it to be fixed and then I want to close the door on this experience. please think twice before you purchase this unless you’re buying it for your RV will update this when or if it is corrected ... show more

    • So far Extremely nice FIRM mattress
I purchased a Dynasty mattress on Amazon 8 years ago and it was wonderful. Over time it got a few sagging spots on each side, but was still comfortable. I ordered this one because I needed a FIRM mattress due to multiple surgeries. This has not disappointed yet. It is SUPER FIRM, my last was medium, and took a week or so to get used to. I am very happy so far and hope it lasts 8 years like the last one ... show more

    • The comfort to sleep.
This bed has made a huge difference for me and my sleeping. It's so comfortable for me, I was worried at first it wasn't going to be firm enough for my back. But it was amazing , I didnt remember what it was like to sleep through the night. I use to be up all night with pain but now I sleep through the night. Thank you so much!!! ... show more
