Diamond
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.
Simmons Beautyrest
Simmons Beautyrest® is a very well known brand that has invested in big advertising over the past several years. They have worked closely with major mattress retailers for generations and offer popular in-store options. With a variety of designs like the Beautyrest Black and Silver lines, Beautyrest is a brand to consider for many. However, not all Beautyrest models are equal, with some of their models having reports of durability issues and their newer online-direct models potentially offering more value.

Diamond's Owner Satisfaction
Everyone wants to look at customer responses before we buy such a pricy product. That said, it's not always easy for shoppers to come up with takeaways after looking at many different mattress sites. We examined the online reviews and sentiment and found that customers give these mattresses above average marks overall. However, some didn't feel as comfortable. Make sure to do more research about the specifications.
Diamond's Supportiveness
A supportive mattress is the secret to having better spine health. If you have a mattress that isn't supportive, you simply won't sleep as well as those that have a mattress that aligns the spine. Most customers were happy with the support from these mattresses, but some had issues with the feel.
Edge Support
Most reviewers find these mattresses to have fine edge support, which is welcomed for those that like to sit on the side of the bed. Some folks that have larger builds may still experience some dipping along the sides.
Diamond's Durability
Having a mattress that is highly durable can save you thousands. Sadly, in this day and age, everything from bedding to clothes degrades faster. Customers give mixed ratings when it comes to the longevity of these mattresses. Mattresses affect everyone differently and some felt happy with the long term comfort, but others were not so sure. If you are considering, make sure to read more before buying.
Simmons Beautyrest's Owner Satisfaction
Making sense of customer reviews can be a powerful tool for shoppers. Sleepers, regrettably, don't always repond positively towards these mattresses. Some have immediate comfort, but othere have complaints. If you are considering, make sure to read on to figure out if one of these mattresses will work for you.
Simmons Beautyrest's Supportiveness
These mattresses aren't the best in terms of support. Though there are some who like the response of these mattresses, others have found these mattresses not to be comfortable. If you like these mattresses, make sure to look at the specifications to make sure it will agree with your body.
Edge Support
Edge support is always important to those that like to sit close to the edge of the mattress Others don't really feel its that big of a deal as long as they are comfy sleeping. Some folks feel strongly about support issues so make sure to do added reading if edge support is an important item for you.
Simmons Beautyrest's Durability
Mattresses with lasting comfort are amazing, but not always easy to find. These mattresses are reported by customers to be not as durable as others. This means that some mattresses still may last years and years, while other customers may have much faster discomfort. If you are a bigger person, take some time reading more before buying.

Really good stuff
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.
It is an okay bed
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.
Best bed I ever slept in.
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!
Not durable
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.
Read this
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!
Initially too soft
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 it!
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.
Needs time
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.
No thanks
Just doesn't feel right for me. Luckily I was able to send it back right away and the customer service was good.
LOVE
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
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
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
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
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
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
I went here as a kid, the owner is a great guy. The location is the best
Comfort that did not last for long
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
Forever Warranty is NOT TRUE
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.
Not what I expected, very disappointing.
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.
quality complain and no hear my complain
i purchase one mattres from aziz&sons ichra but after one month matress complain start but no boday help me if any one hear my voice so plz resolve my issue company and dealer not copreat with me pathetic quality and pethetic customer service from company side and dealer side i waste money purchase diamond foam
Used 2 years
The first year we were happy, after 2 years the mattress is HORRIBLE. I would avoid buying a mattress from them again
worst futon mattress ever
SO SO SO disappointed in the futon mattress we purchased along with a futon frame- which is just o.k. But I specifically ordered the highest end mattress thinking it would be the best quality. I wouldnt take this for FREE- Sagging, lumpy, cant hardley sit on this let alone sleep on it. We paid a lot of $ for this set and if there was a way to return and get my money back I WOULD in a heartbeat. Lets see if anyone responds.
Rally Split King XL bed
A special thank you to Todd Riecke and Patrick Wolf for going above and beyond to make things right for my husband and I. We purchased a bed from a local retailer and they ordered the wrong bed. The local retailer after many calls back and forth refused to do anything about it. I called the company and talked to Patrick Wolf and between him and Todd, we had the correct mattress delivered to us within a week and a half. We love the plush copper infused bed. I can't rate them high enough for quality and service.
Diamond Mattress Warranty
Were so lucky that the our old mattress had a warranty was covered with Diamond Mattress. The service technician came to our house free of charge and checked found our mattress was sagging and defective. Right away they giving us a chose new mattress from there selection we got the Transformation free of charge and delivered to our house. Great Quality and very comfortable love the Mattress. THANK YOU SO MUCH!! such a wonderful people who care for your comfort.
Diamond mattress
Was a comfortable mattress for the short term. After a couple years it started to sag. After complaining to the company and a futile service call , I was sent a letter stating that it was due to body impressions and would service it at my transportation expense. It was a $3000 mistake. There was a bulge on the top sidewall of the mattress. Don't waste your hard earned money on this inferior overpriced mattress. I now sleep on a Beautyrest Black Medium firm.. Much better sleep.

This mattress felt great at first but after only 1 year started to sag on both sides, leaving a "hill" in the middle.
Now we are having back problems and so are replacing it after only a little more than a year. This is a horrible investment,
don't make this mistake.

Mattress is ok for few years but when it does go back, forget about the 10yrs warranty. Simmons will no honor it.. they will try to charge you as much or more for "upgrading the mattress" with no warranty on the replacement! I have filed complaints with BBB but they don't care.
Please file complaints if you have had any warranty issues so they are force to take of the customers!

Wished it was thicker
Steer clear of this mattress!
We just received this mattress today, and it is TERRIBLE! I am writing this review at 1:30am because I can't sleep on it. I have given up and am now lying on a foam topper placed on the bedroom floor, and I am much more comfortable here on the floor than I was in the bed.
The fabric on the mattress is stiff and of very low quality. This shouldn't be a problem because it's covered with a mattress pad and sheets anyway, but it still doesn't "give" for that plush feel. You sink into the mattress, which could be good, except you are met with hard springs and awful pressure points. My husband, a back sleeper, is already having terrible back pains after just a few hours. I'm a side-sleeper, and my shoulder and hip are killing me. I know they say a mattress needs time to settle, but I can't tolerate this bed for a few hours, much less a whole night. I will be returning this mattress.
On my 3rd replacement!
The cheapest made mattress we have ever purchased. I have now had 2 of these mattresses, the first was ripped and sagged in the middle right out of the package. They (nationwide retailer) replaced it with another and it is as bad, if not worse. It squeaks so bad and is so cheap. I paid over $1,300 for a king set and it is completely useless to us. It makes so much noise and racket every time you move. I will never buy anything with the Beautyrest name.

Hills and valleys
Had this restored spirits five years.the last three years were hell. My husband wouldn’ Sleep on it. Contacted Simmons for inspection and replacement. No go. I have spent weeks reading reviews. I am sleeping on this any longer. Moved to guest room until I find new mattress. I will never buy another beauty rest.
A little too firm for me
Thought I ordered the plush mattress, but received the firm. Trying to adjust to this mattress. Good price and good quality.
Comfortable mattress that does not sag.
I could not be happier with the pillow top mattress that I recently purchased. The pillow top seems to help me sleep better and is better for me to sleep on since I have arthritis. The mattress fabric is of excellent quality.
Good mattress.
This mattress is nice and comfortable. Good deal. I picked this mattress out online. I've never bought a mattress online before. Fortunately, it worked out. Good choice.
This is a fabulous mattress
The mattress is nice and firm, pillow top just as I ordered. I was very surprised at the excellent quality of the mattress. Have got no response to the advertised gift card. It was supposedly mailed separately 2 weeks ago
Love, Love, Love this mattress.
I tried many mattresses in 4 different stores one Saturday and most were fine but as soon as I lay on this Simmons Beautyrest, something felt different. I walked around and tried a few more then came back to the Beautyrest. I knew it was the one - perfect pillow top yet firm as I like it. No more sleepless, tossing and turning nights!
Not for a person with a bad back
Purchased the Silver but only kept it 3 weeks. Was good the first week but by the second week started to break down. By the third week it was squishy and made my back worse. If you have a bad back don't buy a pillow top. They tell me now that I am returning the mattress. Penney's does not refund your money so am having to buy a different mattress. Originally told I had up to 100 days but that is no longer true, it is now 48 hours. Who can tell if a mattress is right for you in 48 hours. Wish I had not purchased my mattress from Penney's. Buyer beware.
Not what I expected
VERY DISAPPOINTED. NOT WHAT I EXPECTED. THIS QUEEN SIZE MATTRESS COULD NOT POSSIBLY BE WORTH APPROXIMATELY 1800.00(I DID NOT PAY THIS PRICE) BUT IT'S NOT WORTH THAT PRICE! JUST NOT SATISFIED. SEEMS CHEAP, NOT TOO COMFORTABLE. DOES NOT FEEL LIKE YOU'RE SLEEPING ON A CLOUD, NO WAY! I PURCHASED ONLINE, BIG MISTAKE! GO TO STORE PERSONALLY TO CHOOSE YOUR MATTRESS.
Excellent product, I just love the firmness!
I think this is an excellent mattress. The only thing was the delay in getting the mattress whic paritally was my fault since I ordered the wrong one at first. Oerall I am very pleased with it!
Great mattress
I thought it would be a little softer on the top but I still sleep great.
This product is not as firm as I expected.
This product is not as firm as I expected. I was hoping it would get better as i get used to with it but have not seen the result as of yet.
NOT AS FIRM AS I WOULD LIKE
It seems to be very well made; movement dampening is good. If you want something firm, this probably isn't what you want. I am a stomach sleeper and the plush doesn't really support the arch of your back.
Best Bed
This bed is very comfortable. It's like sleeping on a cloud. Great buy.
Not a good value
Mattress feels like its years old already with height changes that make it uncomfortable
the first 2 weeks has been great !
Most mattress start out great, the real test is over time. We hope it last years as it should with out sagging or breaking down
Great product, great value!
I love this mattress! Quality is great and the opportunity to use coupons and earn rewards is awesome! The company that delivered the mattress was great also.
This Mattress Is Better Than Advertised, It's So Comfortable!
I was looking for a firm mattress, and found it in this Simmons Beautyrest Silver Snowhaven Luxury Firm Mattress! It's A Five Star Rated Bed, That I Guarantee Will Give You A Five Star Night's Sleep!!
Not as hoped for
Problems with delivery, didn't get it until over a month after ordering even though we're home 4 days out of the week. After only a couple of months with the new mattress, it already has 2 slightly sunken spots where we lay, and we are not overweight people. I've heard that Simmons makes a better mattress if you are willing to pay a lot more, but this apparently isn't one of those.
Best sale price available at the time.
previous mattress was a Beautyrest plush king. Wanted a little more firmness but full firm was too much. The luxury firm was just right. Took a week or so to get used to the extra firmness but now we love it. Also, this mattress is nice and thick so it works well on a platform style frame without the need for box springs.
Wonderful Mattress!!!
For the first time in months I slept like a baby the very first night I got this mattress. Firm yet extremely comfortable. I just love it. I tried a Saatva brand luxury firm mattress and it was terrible. I had to come back to Beautyrest and I'm glad I did.
Very comfortable
The salesman was so easy to work with. And the delivery men were great.
Very comfortable bed
This is my first bed purchase without actually trying the specific bed first, I tried a few out at the local store and then saw this described online. I was nervous but the product is actually good. Only complaint is it took over two weeks for delivery
This mattress is great buy.
This mattress is great buy. I originally planned to get a tempur pedic. I then switched to a Stearns and Foster. In the end this was the best mattress at a great a price. It was more in my budget.
Nicely made mattress..perfect for a good nights sleep!
We finally chose this new mattress after much research. We were scared of so many choices available, but not a lot of positive reviews on most of them. With backaches every morning for my husband for awhile now, & now mine starting to hurt, we knew it was time to take the leap & buy a new one. I was shopping at Penney's for towels while my husband waited in car, when I seen the mattress sale. So I went & got him & made him lay on a few. He chose this one & the very first night he slept like a baby, & has ever since. We both wake up with no soreness already. It is a tall mattress & we bought a new box spring as well, so we have to slide down out of bed. But we love the height of it right now. And maybe as we get older we'll have to get a step on each side, or go with the standard bed frame. We have a lovely vintage oak bed with side rails, so both pieces had to sit on that. So it is tall now! So if you need lower, suggest buying just the mattress & sitting it on the plywood (as suggested for warranty)..I would still like both pieces even if I had the lower frame. So we love it & would recommend it. Pretty too! Love the navy blue sides.
Great Decision
It is so difficult to choose a mattress that you have confidence in, but this mattress is great! It is firm but well cushioned. It is also beautiful. The excellent delivery and set-up service is also appreciated. Virginia Jones
My daughter loved it!
My daughter loves her new mattress. She actually took her thousand stuffed animals off the bed so she could really enjoy it.
Great
This bed is very comfortable, I would recommend to anyone.
this product has simple and easy features
simple only need 1 no need for box spring and comfort is amazing .. fits to you.. feeling someone else kicking is very mim.
Delivered when quoted.
Price was great, had to wait on delivery, but received when quoted by very nice employees an they removed old one. Mattress is firm but must be covered by mattress cover for warranty i believe.
