This mattress is wonderful for my elderly parent. We have it on an adjustable bed and it is just the right amount of firmness vs. softness. The workmanship is really nice and it is an attractive product. My parent is loving this mattress.View More Reviews
The first night on this bed was the best nights sleep I've ever had. Its like angels made my bed personally using magic. Im truly in love and completely satisfied.
Best mattress I ever slept on. Always had the expensive pillow tops but either to hot or back problems. I love this mattress.
Called manufacturer about return if necessary, and related costs. Remember, it's MUCH bigger if I have to return it. Beware: if u happen to not like it, u will pay over $100.00 shipping, plus incurred costs if u have to get someone else to take this FULL QUEEN size mattress to the shipping point because u can't lift it! Thought u might want to know.
Excellent. Did take some days for it to unwrinkle.
AAAAHHHHHHH!!! A little too soft.
Well know I am ready to review my King Memory Mattress, we have had this mattress for 18months and it has been Awesome!!! I highly recommend it.
Bed hurts back. No support
Nice looking bed, but take note that it is ULTRA FIRM - which is fine if that is what you are looking for. Took several messages to get a response from company and told that customer is responsible for return shipping. Since mattress is inflated to full size - freight shipping is several hundred dollars so we ended up keeping it for spare room.
I purchased this bed because it was listed as medium firm which is what my last dynasty mattress purchased 8 years ago was listed as. This mattress is much more firm.
Slept on it 3hrs after opening from the vac seal. My girlfriend and I Did not notice any smell and slept great same with our 70lb pit bull..Lol Shocked that it was just as comfortable as my $3000 sleep doctor bed that was less then 2years old and also that's the best bed I've ever slept on. Only reason for getting a new one was because it was a split king. I've had back problems for over 10years (2 hurniated discs, fractured vertibrea, muscle spasms and sciatica.. hinse the split king zero gravity adjustable frame. Now that my back is bettrer I can sleep flat now with this new king bed. I dont have to worry about waking up in the crack anymore!!
I had high expectations for this mattress! It is uncomfortable and leaves ridges where we sleep. Yes, I turn the mattress every couple months, and the ridges just become more ridges on top of the old (now sideways) ridges. Very disappointed and hunting for a new mattress!
Enjoy my new mattress, it is soft to the touch but firm enough for good support. My shoulders feel a lot better where they was achy. Both mattress and free pillows expanded to full size within minutes wheras it says that it made take up to 72 hours. Pleased with my purchase.
Our guests love this mattress and told us it's extremely comfortable. Laid on it ourselves when we first got it and were shocked it wasn't as firm as the other ones we had bought. It's been a month and we think the mattress has fully filled up, which it's now firmer than the 1st day we bought it. Comfortable.. we always recommend dynasty mattresses to our friends & family!
mattress is NOT PLUsH but very Firm !
Horrible mattress! Very firm! Like laying on a board. Have the worst neck and backaches! Plus there is no cooling gel. It gets very hot to sleep on. Will be sending this back. Very disappointed!
Took all my hip, back and shoulder pain away!
The Dynasty Mattress arrived in a box and handled well with a 2 wheel cart. The box it came in was marked soft and almost no odor when expanded. We listed our 5 year old 1800.00 Beauty Rest sagging Mattress for free pickup on Face book Marketplace it received 20 calls and was gone in 2 hours.I weigh 240 lbs and my wife about 170 . We have no backaches since we bought this mattress (from everyday backaches). We have had this mattress 5 months with no sag. We are in our late 60's and sleep all different ways ( side stomach back close together )The mattress feels firm but, compresses the right amount for a good nights rest. We do have a padded mattress cover. Yes we would buy this high mattress again.
First I want to say there is nothing wrong with the quality of the mattress. My issue is that this falls in the firm category and I was looking for something plush. As a side sleeper this fact has caused me excruciating back pain. If you're looking for an inexpensive, quality, firm mattress, this isn't a bad choice. If you want something to sink into after a long day, keep looking. I balanced all of my 220 lbs on the heel of one foot and sank in all of 2 3/4" I of course tried to tough it out and break it in as most mattresses need some time and only succeeded in running past the return date, not that I'm sure how that would work as it expands to about 5x it's shipping size once opened. I've purchased a better, much more expensive mattress locally and will resell this one to someone who will enjoy a firm bed. There was a slight odor as expected when I opened it, left it in the garage for two days and it aired out just fine, no complaints there. I may have gotten a defective one, but I can't even call this medium, it's very firm.
I will never buy another spring loaded mattress again. This bed is amazing! Last night was my first night sleeping in it and I slept ALL NIGHT without any issues. It's super quiet, I didn't sweat at all throughout the night also you cant feel the person next to you move which is great. My baby is 4 months old and every since I was 3 months pregnant my hips and lower back have hurt so bad from my previous mattress (BeautyRest aka Trash) , but this morning was the first time I got out of bed and wasn't sore, achy and, stiff. This mattress has brought me long overdue relief. And it just keeps growing! I love it and highly recommend it. Also I didn't notice a smell and the pillows are amazing too
I’ve had this mattress for almost a month now. I am pregnant, so sleep doesn’t come easy these days, but this mattress is awesome! I can still feel some of my boyfriends movements when he tosses and turns, but it’s a huge improvement! I’m not sure how cool it is, but this is my first experience with a memory foam mattress. Mine came with 2 pillows. Be sure and get yourself a waterproof protector to protect your investment. That is a must have!
Have tried it for a month. Not worth money. Sagging around edge and in the areas we sleep. Also back hurts worse than before. Hopefully they have a hassle free returns/refunds.
Awesome bed. We sleep so good! Great buy. It is heavy so have some help if moving it upstairs.
I can't say anything bad about this product, including the 2 free pillows! Its soft yet firm, no chemical smell, rose within 3-5mins to full size, is relieving my husband's back pain, is not hot at all. We are in love with the product.
Best Mattress ever!
No major smell as reported by others. Took shape quick. Very comfortable. Time will tell about durability.
This mattress is so comfortable u can't go wrong . We wouldn't trade it for anything super soft
Too firm. Definitely not a plush.
Amazing.. great quality sleep on firm mattress. Perfect fit. Meets all expectations, already recommended it
The Mattress was delivered Friday, and set up to expand for 72 hours, we slept on Mattress Saturday evening but it's sagging in the middle!
I was looking for a thick mattress that wouldn’t leave holes in the bed from where you lay. It springs right back up. True definition of memory foam and bonus pillows were awesome! Didn’t have chemical smell but does need some time to inflate after coming out of the box. Love how thick the mattress is!
I was aways old school coil spring mattress guy. Wow so glad I tried the new foam gel. Delivery in a box of a queen size bed to your door. Crazy! It's pretty heavy getting the box upstairs but two people can handle it. Unboxing was easy. When you cut the plastic off be careful not to damage. Then get out of the way for the expansion. The two pillows could be over looked they are flat under mattress. I had opened it about 4:00 and by 9:00 it grew to pretty much full size. It took a night or two to get use to the new support. I use to toss and turn all night with cover's all wrapped around me and sore back. Now don't remember going to sleep or that morning is here already. Very happy with it so far! My son is buying one now.
This is the most comfortable mattress I've ever slept on. It's a bit too soft bit overall it's comfy. The price is amazing and my back is no longer stiff in the mornings.
I love the mattress! It's firm but still has a nice give to the memory foam. The chemical smell took forever to go away otherwise I would give it 5 stars.
I haven't slept on it yet, but it seems that this thing keeps growing and growing. I purchased it for a Bookcase storage bed, needless to say, I will have to purchase a step stool to assist me getting on to the bed. To the touch, it feels good, but I won't know until I actually sleep on it....... as soon as it stops growing. Update: Today is day three and the mattress has grown to 14 inches and has another half inch to go. It is big and tall and very heavy. This is the third day of it being on the bed and it does have a musty chemical odor. I still haven't slept on it or climbed upon it, but I will leave it on for another two to three days to see if the odor goes away (open the windows) and to see if it will complete the growing process. I will either send it back if the odor doesn't dissipate or buy a bed step stool to climb this mountain. See the images.
I've been searching a while for a good brand mattress and im so glad I found this brand. I love this mattress, it is better than my old Zinus foam mattress. It does have slight chemical smell at first then it goes away. Came in big box, airtight. It inflated in 30 mins. Id give it a 7 on plush scale and a 7.5 on the firmness scale. Doesn't feel hot like my old mattress too. Def worth the money.
I can finally sleep directly on my side again! No more twisting my upper body opposite of my lower because my expensive pillow top spring mattress killed my shoulders and hips!
I am so happy with this purchase! The bed is amazing!
This bed is awful. We loved it for 2 nights and then it turned into a rock. If you wants a soft or even remotely plush bed this is not it. I wake up sore every morning and reverted back to my old bed while this mattress sits in my storage.. I would just sell it off but I wouldnt wish this waste of money on anyone. And when you try to reacj out to the company to try to find som kind of resolve, they compleatly ignore you. Do your self a favor if this.is your only bed option and sleep on the floor because this bed is the WORST.
We bought this mattress over a year ago...had no idea that they sold a separate foundation. Spent months replacing the bunky board we got from Crate and Barrell 2 times and dealing with back pain, even called the mattress mfr. The mattress mfr said they recommend their foundation instead of bunky board. Ordering it today, hopefully it will take care of the problem but paying $50 more than if I bought them together from the start. They need to update the description and recommend the foundation if they don't buy it separately OR don't even sell the mattress alone. Description said it needs a 'solid' foundation...what does that even mean? I had a hard time trying to find a bunky board that is solid wood from many retailers. Crate and Barrel's new bunky board is made of compressed cardboard! A painful process, but I like the mattress.View More Reviews
The mattress is definitely on the firm side but we both find it about right. After 11 months, the bed seems to be wearing very well... no signs of change in feel or shape. The adjustable bed is used in zero gravity every night for one of us and not used at all for the other. The adjustable bed works well for back sleepers but not side or stomach sleepers.
This bed is the best we have ever slept on, even 6 years later. We have the queen, and now want a Cali king (we now have a dog sleeping with us), and will be buying another one of these latex matresses from Costco. This one will go into the guest room, and it looks brand new. It has not settled or sagged at all, even though it is used every night, by 2 people. It is NOT hot, either. The memory foam mattress we bought from Costco first, was hot, however. So we returned the memory foam and got this latex mattress. We are so happy!!!
I did what i thought was plenty of research before i bought this bed.. I've waited a full year to try and get used to it, and kept telling myself and my spouse it would get better. Not only was it hard and uncomfortable but, from 3 months on, it had big depression on both sides. It seemed to get worse , not better! The only good thing is i bought it from Costco, so they agreed to take it back, no problem! Yea Costco!!
I bought this bed on July 7, 2016. It was my first Costco online shopping. As in warehouse shopping, the online service was very good. The delivery company did not call me to confirm the delivery time but Joshua and Carlos did great in the delivery of the bed and setting it up. Brandon at the distribution center was excellent. I could test the bed before the purchase. The latex mattress feels cool in summer compared to other types of mattresses. I hope I enjoy my bed for many years to come. I love shopping at Costco!!!
I've purchased 3 of these mattress so far. The first one about 3 years ago, then another one the following year and another one a couple months ago. the first one was in a guest room and the other two were for two of my kids who loved the bed when they slept on it while visiting!
I bought this bed over 2 years ago, maybe 3 years now. My husband was a reluctant buyer, because we are only early 40's :) He thought adjustable was for the nursing home. But he had enjoyed it just as much. It hasn't helped his snoring, but he enjoys the leg elevation and massage features after a tough day or workout, and elevation of his head when congested. I have had a couple of back injuries from car accidents, and sleep considerably better on this bed than ANY OTHER!! We had a memory foam before this. This is NOT memory foam. Memory foam sinks in with your weight, then when you turn over you fall back into the rut you created. Ours was also hot. This foam doesn't radiate heart back at you. I love that! It doesn't sink in. It has great support. It is nice to be able to sleep elevated without getting up in the middle of the night to prop up or go to the recliner. My bed sleeps just like it did almost 3 years ago. No sagging, indentions, or soft spots. It does creak a little when adjusting, nothing a little wd-40 can't fix. The base and massage features still work like a top. No problem! Good buy!
Purchased and received this split King organic mattresses with adjustable bases on April 8th, 2016. What a great product! Both my husband and I absolutely love our mattresses! The adjustable bases fit perfectly inside our existing bed frame, and the mattresses are sooooo very comfortable. I have always been a side sleeper, but no more! I'm able to easily sleep on my back now. Since I am a professional singer, this is a real plus for me. Also, the adjustability allows me to (among other things) raise my head ever so slightly to allow for sinus drainage as well as legs for additional perfectly tweaked comfort. The mattress cover is soft and also feels luxurious. A 3 inch layer of softer 19 ILD natural latex perfectly compliments the firmer 32 ILD layer underneath it to softly cradle with no pressure points yet support my body superbly. Adjustable base works great. Fully articulates for customization. Zero Gravity pre programmed position is heavenly! Don't wait. Buy this now!!! You'll be glad you did! Great price and great product. Thanks Sleep Science - Well done!
We got this bed a couple of months ago. It is very comfortable. Unaware another person is in the same bed. Mattress is fine for us, not too firm and not too soft. No odor.
Delivery company had great personnel.
One side had a control box (located under the bed) that failed in the first few hours. Costco called the company and we had a new one installed by the company in a few days.
I would suggest going to check out Dreamfit mattress covers (they come in twin xl and their kings sheets (2 twin xl bottom sheets with one King top sheet. Their bottom sheets and mattress covers have extra elastic straps to hold the sheets in place. I found these after much research. They stay in place great. Love my bed!!
The mattress delivery was great..even on time. The mattress itself is nice ...no sinking in like foam. Soft and supportive. The adjustable base is great. I do wish the lights on the remotes would come on before you try to poke the right button. Zero gravity setting is awesome!
Its very comfortable. Firm for support but not too firm. My wife & I think it is the best mattress we have slept in. No smell at all.
Disagree with the SUBJECTIVE product details 'Sleep Science comfort scale: medium with a bounce.'
There is missing objective ILD firmness scale info in the product details. For me, 5'3 and less than 120 lb, this is surely a soft latex mattress. In general, The 'soft' designation corresponds to an ILD rating of 19-21. The ILD rating for the medium range is 24-26. After digging yourself, then you find this mattress has ILD 19 on the top 3 inch layer over another 6 inch of 32 ILD.
