Diamond mattress is a family run mattress company that has been in operation since 1946. Their big differentiator is that they actually make their own pocket coils and process their own memory foam. This is a bit different than many mid-tier mattress companies that outsource their manufacturing. Their specialty is pocket coil and innerspring mattresses, though they also build memory foam mattresses as well. Most customers like their Diamond mattresses, but there were some that had issues with durability and initial feel.

Having a mattress that is great for durability can save you thousands. Unfortunately, nowadays everything from what you wear to where you sleep degrades faster. Customers have mixed feelings about the durability of these mattresses. Mattresses really affect people's bodies in different ways and some folks felt great about comfort long term, but others were not as sure. Make sure that your mattress choice works well with your body before purchasing.
With data from customers, you can more accurately choose the right mattress. However, there are a lot of other brands out there competing for your attention. Customers report feeling both positively and negatively about these mattresses. Some report feeling comfy in their new bed, but others report not feeling as good.
Whether a mattress is supportive or not is the difference between comfort and pain for stomach and back sleepers. Side sleepers also need deeper support and a responsive mattress for their hips and shoulders. These mattresses do well overall with support. That said, some others didn't like the support so if you are heavier, make sure your choice aligns with your body.
Most agree with the edge support of these mattresses. But, some heavier customers may experience some dipping close to the edges.
Reviewers provide mixed ratings about the durability of these mattresses. We're all big fans of mattresses that feel just as great as they did 10 years ago as they do today, but sadly, not all mattresses are built for lasting comfort. If you are thinking about buying a new mattress that isn't an A+ on durability, make sure to do one last look at the warranty and return policies so you are protected.
Not as good quality as I was expecting, but you get what you pay for.View More Reviews
I can't complain about this bed -- I am really happy with it and it feels comfortable to me. The only annoyance was that the shipping was late getting to me.
I've had a diamond for a couple years and it is definitely an okay bed. My hubby likes it more than I do. I want something more luxurious.
My last three beds are diamond beds. Their longevity isn't as good anymore, but I still love their products and stand by them as a good bed!
My bed started falling apart after only 3 months. It feels as if you are sleeping in a valley 10'' deep. We are not heavy people. After 9 months on the bed, we couldn't take it anymore.
We had two prior Diamond mattresses that we loved so we thought that we should get a third. We finally found a place with one and that is when the problems started. After only a month, it started to sag. It was like sleeping in a gutter. I called and they sent an inspector who said it was a 7/8 sag, which is within the normal range. The problem was when you get on it, it sags way worse. Sure, I am 200lbs and 6 foot, but my wife is the only 100lbs and the same thing was happening to her!
Purchased the Ethos latex mattress 6 months ago. At first it seemed comfortable, but after 2 months we couldn't sleep on it. We rotated it but nothing helped. Every morning I woke up in terrible back pain. Then I found out that the latex wasn't even latex. 80% polyurethane foam, 6% rayon & 14% latex! This seems like blatant fraud to me as this was very expensive and we thought we were buying pure latex. Very dissappointing.
I love soft beds and this one cradles me into a cocoon every night. I absolutey love the way it feels and think it is perfect if someone loves soft mattresses.
Maybe it is too soft for me because I feel like it is taking my body some getting used to. But the materials seem to be high quality so I am hoping that my body adjusts.
Just doesn't feel right for me. Luckily I was able to send it back right away and the customer service was good.
I am finally sleeping through the night again. I had an awful spring mattress and so happy that I opted to get a new latex bed.
I have purchased four mattresses from them over the years and am getting ready to purchase a new one. Not that the others need replacing, they are still in great shape, they were left behind in a move unfortunately. Dollar for dollar you won't find a better mattress anywhere. They are incredibly fast as well.
HORRIBLE place. I called and spoke with a salesman 2 days before I went in because their store is about an hour away from where I live. I told them exactly what I needed (I needed a custom mattress for my RV). They gave me prices of 2 different mattresses and explained to me the difference. I thought the prices were fair so I showed up and Nick was completely unprofessional. When I told him which bed I was most interested in he quoted me a price almost $250 higher than what I was told just 2 days before. He told me that whoever told me that does not know what they are talking about and he was sorry. I told him sorry does not pay for my gas to get down here. Sorry does give me back the time that I lost. Again he said he was sorry and there was nothing he could do. I even had proof of the prices I was given. When I told him I was going to take my business elsewhere he said "you think you can find a custom mattress for cheaper". I told him I know I can. Later that same day I bought a custom RV mattress 60x72 for $400 including taxes. Plus the mattress I purchased elsewhere was softer, had thicker memory foam, included a cool gel memory foam and had a better warranty. Stay away from these guys. They have no clue what customer service is. The first guy I spoke with on the phone was great but when you get there it is a completely different story. They will jack up the prices at least 35%. Trust me there are better options out there for a custom mattress or a regular sized mattress. You would think getting it directly from the factory would be cheaper but that is definitely NOT the case here.
Don't waste your money on this product they won't stand behind it when it counts. I bought this mattress because the sales person told me they would back this product if there were any problems. Well five years into a twenty five year warranty the side seams have pulled apart and the memory foam has failed badly. they sent out a contracted inspector who;s only job is to deny claims not provide the customer with quality service. Save your hard earned money and buy anything else !
They aren't so helpful with a warranty unless you live there. Don't buy these mattresses outside of Utah because they will tell you to send the mattress to them at your cost THEN they will determine if it qualifies under the warranty and they will "fix it". Then you pay to ship it back to your home, even if it falls under their scope of warranty. Bad customer service!
I've bought over 20 mattresses through the years and my uncle bought hundreds. Ernie is the greatest. Can't believe how he can hoist a mattress on his back and carry it. Hope you are well!
I went here as a kid, the owner is a great guy. The location is the best
I have owned the Ethos – Tranquility Luxury Medium Mattress (Approx. value $2800). Have been very satisfied with the mattress for around 3-4 years. Even though I have owned this mattress since October of 2014. The mattress was delivered to my Southern California residence in Santa Clarita. During the 1st year of purchase. I have only slept on this mattress once or twice for every 60 to 90 day period, It was not until September of 2015, when I have fully moved back from my Northern California address did I sleep on this mattress on a daily basis. So I have really had a good 3-4 year comfort experience before the mattress started to show the deformity. This deformity has resulted in not being able to sleep on my side of the bed due to the sagging of 1.5 to 2.5 inches over approximately 25% of the mattress. This uneven sagging is observable without the need for anyone to sit or even lean on the mattress. About 4 weeks ago I have contacted the reseller from whom I have purchased this mattress and was given the manufacturer contact information. I contacted Diamond Mattress and was required to submit photos and fax over a warranty claim form. Diamond required to send over an inspector to document and process the warranty claim. Diamond Inspector showed up on April 10, 2019 and took more photos and was able to determine that the deformity maybe corrected by replacing the broken bed foundation. The bed foundation was purchased along with the mattress as supplied from the reseller which happens to be original Diamond Mattress foundation. Additionally, when inspecting the mattress the Diamond inspector was able to expose 8-10 inch tear in the mattress stitching (not related to the foundation issue) which was only observable upon turning the mattress bottom up. The inspector said that Diamond Mattress will contact us within a week. On April 18, we heard back from Diamond and were told that even though the warranty would cover the mattress for 10 years, the mattress foundation would not be covered? Asked about the tear in the mattress and he said something along the lines 'we should have reported this issue upon purchase'? I am speechless as to the lack of common sense of that statement with which the Diamond representative insulted our intelligence. How can the Diamond representative assert that the tear in the mattress was already there upon the time the mattress was purchased and delivered? And assuming that was correct, where is the quality control in releasing and shipping a defective mattress and foundation to a consumer? And how many consumers are likely to flip the mattress on its back looking for such a defect? The mattress warranty states that it may be void if the wrong type of foundation is used. However, even when Diamond has supplied their own foundation, Diamond Mattress would not honor their warranty. My experience has demonstrated that Diamond Mattress Warranty is a lie. Diamond should have stood by their product and I should have been provided with a non-defective foundation for this very expensive mattress set. Bottom line close to $2800 investment in this mattress set which is really only worth to me less than $1000. Effectively, when I have purchased the Diamond Mattress product, I have lost close to $2000. My recommendation to anyone who does not want to go through a similar experience D o N o t B u y a D i a m o n d M a t t r e s s
I purchased a Diamond mattress (Spinal Comfort) and paid more than I would have because of the 'Forever Warranty' feature sold me. I recently filed a claim because the upper portion (pillow top) is sagging. Diamond Mattress sent Integrated Bedding Group and reported 3/4" depressions on both sides, left and right, and the top left has shifted outward 2" in a 64" long area. The report also includes a faint yellow 30" stain. This was a pee stain from my baby. John, Diamond Mattress Warranty, said the stain voids my warranty. I explained it is a faint stain on the right side and the pillow top of the mattress is sagging on the left with a length of 64". This does not make sense. There is definitely a defect in materials and/or workmanship. FOREVER WARRANTY IS NOT TRUE. DO NOT FALL FOR THIS FEATURE.
I bought a Diamond Sleep Princess Pillow Top Mattress last Fall and was really looking forward to finally getting a good night's sleep. I got it home and set up and while it was ok at first, within the first three months it started sagging in the middle and has only gotten worse. Maybe I should've chosen a slightly firmer mattress, but all I know is for the money I paid, I'm very disappointed in the quality of this mattress and will never buy this brand again.
I am soooo glad I decided to go with this mattress!! I no longer toss and turn or wake up at night. This mattress is truly amazing!View More Reviews
This mattress may not be enough support for my guests
we love it:) super comfortable
Just got my bed set up last night, love it! It is very comfortable
Im in love with the product. mattress is soft and comfortable. its good quality and i would buy it again. its definitly worth the money! i also like that it came with two memory foam pillows! you wont regret the purchase.
Good for bad backs. Keep you nice and cool.
I did not know how a mattress like this one would work..........found out!!! Love it! It is so soft yet firm and does not give in, just holds you in a position that lets you rest!
BEST PURCHASE EVER!!! After using a 16" Foster and Stearns mattress and box spring...I'LL NEVER GO BACK! The PostureLoft Milan 14" Queen sz Cool Gel Memory Foam Mattress is a dream! As are the pillows! After 6- years of owning the Stearns and Foster set, the 4" pillow top sagged, causing my hips, shoulders and low back to be in constant pain. I no longer sleep with a pillow between my knees to keep my hips balanced. And throw away the heating pad or blanket! You will sleep deeper and more comfortable because the gel evenly distributes your own body heat creating that "cocoon" effect.
This mattress has helped me tremendously. No more back pain...and I am sleeping through the night. After researching for about a month, I decided to order this one because I figured that if i didn't like it, I wouldn't be wasting thousands of dollars (compared to other brands.) This was the best ***ish dollars I have spent in a long time!
I MUST SAY , I AM VERY PLEASED WITH MY NEW MATTRESS. THE BEST SLEEP I'VE HAD IN A LONG TIME.
The mattress is comfortable and the support is good; the packaging is very convenient as well. I would say it does get on the heavy side once it's done expanding but overall I loved this mattress. I'll probably go for a softer one but that's based on personal preference.
This mattress is perfection! Perfectly supportive, while at the same time being just the firmness, but not too firm. This mattress is just right!
The quality of this mattress is top notch but it is definitely much firmer than a medium firmness. The mattress didn't have an odor like many memory foam mattresses often do at first which was nice. It doesn't really have a cooling factor too it but definitely is still a great mattress.
Just as advertised, great sleep.
I bought two of these mattresses, one for me and one for my adult son. One is very soft and one very very firm. They both came on the same day so I would assume same shipping location but must be different manufacturers or there is no quality control. My son set his up first and it is super soft, probably too soft to last. I was going out of town so we set mine up so it would be ready when I came back. Immediately we saw a difference. Mine jumped to the 14 inches within an hour and his still was not 14 inches days later. I don't think it even is now weeks later so I am guessing it will never be 14 inches. We are considering returning but we have already given the old mattresses away. I am not sure how the company would handle a return that is not what was purchased since it would be a real problem getting them back in the box. It will be a crap shoot on if your mattress will be super soft or super firm from our experience.
Not too hot, temperature wise, like other memory foam mattresses
I wanted to give it a few months of use before rating the bed. While I'm happy to say this bed is everything. I purchased a high end bed for my master bed and purchase this for my guestroom and I'm sorry I purchased the other bed at all. I could have filled all my bedrooms with these mattresses for the cost I paid with that one bed. My husband who was skeptical of buying a bed online, is now sorry we didn't by more. It's cool, firm but comfy.
This mattress like sleeping on Cloud. My wife loves it. She was smothering hot at night . Not now.
I couldn't find a good quality mattress before at this price, it includes the tax and free delivery, it was awesome, I love it!
I was very hesitant to order a mattress online, but I have no regrets about this purchase. This is the most comfortable mattress I've slept in. It beats out my previous more expensive mattresses. Quality does not have to break the bank!
This mattress was for my daughter and she is very pleased and finds this mattress very comfortable and at a good price so I'm happy!
