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.
Sleep EZ has been a popular latex mattress maker for decades, specializing in mattresses that use 100% pure latex and range from organic to all-natural. Having been in family-business since 1976, one of Sleep EZ's selling points is having the experience to make 'safe mattresses for the family.' They have a variety of products in competitive price points with interesting differentiators like: flippable and dual-sided mattresses.

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 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
The first year we were happy, after 2 years the mattress is HORRIBLE. I would avoid buying a mattress from them again
I’ve bought two of these mattresses. Excellent quality, super comfortable, and absolutely no chemical smell. I’ve spent 6 months researching mattresses with concerns about health, comfort, and quality. I finally decided on the organic latex. I found this to be the cheapest site to buy from (despite the fact that I live in Canada). We are planning on buying 3 more, as we are a family of 6. It’s the only mattress our family will ever use and the only one I’d recommend without hesitation.View More Reviews
We purchased a full mattress for our guest room. This company is the best! Excellent customer service, shipping, packing. Mattress is super comfortable and has gotten rave reviews so far.
We purchased our dream vacation home, so we wanted our dream bed. We purchased the exact same king set up that we have at home. It’s so comfortable, we just love our bed and now there’s no getting used to a different mattress. Shipping is very quick, and easy. We also purchased the new Roma Mattress for our guest room. Our first guest said it was great!! I am constantly recommending SleepEz to anyone who will listen. Thanks SleepEz!!
Best Ever with the option to change firmness once you order it. Your never stuck with what you thought you wanted. Great customer service, friendly, helpful people who only want to give you a great mattress buying experience! Larry Kitchens in Norfolk Virginia
This mattress system is truly amazingly comfortable. As someone who had no problems sleeping on my 20-year old mattress, I can attest this is incomparable and that I sleep even better. Before I would have a few minutes before falling asleep, now I am out almost immediately. Combined with silk and linen bedding, it is such a luxury and comfort. The mattress came in three boxes and was simple to set up. The video on the website is helpful. Basically, you spread the organic cotton and wool cover on your bed and assemble the mattress components based on your preferences. The system is very versatile, with different layers and firmness can be combined. In addition, for queen size and larger, each half of the mattress can be different. It is a really amazing experience to sleep on this mattress. I also got full bedding and several pillows made of the same awesome latex. I fully, highly recommend it from personal experience.
First time user of latex mattresses. So far this has been a great experience. Sleep EZ Customer service is great too! Those guys will work with you in resolving any issues and their recommendations are noteworthy as well.
I love my new mattress! No more back pain.
I bought 13-in Natural Latex Mattress with All Talalay layers (firm, medium, medium, soft). Originally, I was afraid that it's going to be too soft. I was so glad I decided to order it! It is soft enough but you are not sinking in it. Love it! My husband loves it too. I sleep in all positions (on my back, sides, and abdomen). Delivery was fast. Packaging was good and secure. Took little bit time to unpack it, but no problems with it. It comes with free sheets, pillows, and mattress cover. No smell, no defects. Easy to put layers together. Thank you, SleepEZ!
My boyfriend bought this mattress last year because I complaining of having back pains. I have not had any back pains since sleeping on this mattress. I just purchased my house and the minute I got my keys, I called and ordered another of the same mattress for my new home. Now we have the same mattress is both our houses. I would buy this mattress for my guest room but I am afraid they will nit want to leave. Thanks Sleepez Am really sleepin E Z Z Z Z!! (Sleeping easy)
Haven’t slept this well in years. Forgot what sleeping well felt like
So far I like it
Excellent customer service! We called during a sale and got a recorded message saying that they would call us back if we left our number and a brief message and they called back promptly and were extremely knowledgeable and friendly. Then when we called in our actual order, the customer service representative couldn't have been any more pleasant (I'm sorry, I can't remember her name!) and was very helpful with some more questions that we thought of. First rate outfit all the way, would definitely do business with them again!
The mattress is very comfortable. I also like the ability to change the layers to adjust firmness.
A very comfortable mattress. Very professional and knowledgeable sales personnel. With the split mattress it is very easy to set up different firmness levels for his and her sides.
Our previous mattress was a Simmons Beauty Rest with pillowtop. What started out as a mattress we liked, became a mattress we loathed. Lots of sleepless nights and pain in the morning. Our online hunt began for the perfect replacement. I first started reviewing memory foam but after a lot of research, I decided against it. I am so glad I did my homework. My search brought me to an unbiased reviews site sleeplikethedead.com. I discovered latex was the way to go for me. I compared several mattress stores recommended on the site and really liked what Sleep EZ had to offer. The purchase was seamless. I received a phonecall after I submitted my online order and was even more impressed with their customer service. All of my questions were answered and then some. My mattress arrived about 5 days after ordering. Assembly was a breeze. I was expecting to have an adjustment period but I instead the pain I was experiencing with my old mattress immediately went away. I sleep cool and comfortable every night. Don't hesitate to make the switch and go with Sleep EZ! They are incredible!
Today is day #25. So far, so good. I'm almost 100% sure that we won't sent it back, even if we decide it's not for us. You see, the worst of this mattress is far superior to the old Sleep Number we got rid of! Seriously, I expected to like it, but my husband likes it too. The jury is still out on whether I'll swap the soft top layer for a medium one, but probably not.
I have artificial hips, shoulders, and one knee. The bed is so nice and soft and there are no pressure points. Best nights sleep I have every had
hips don’t hurt
Great (incredibly great) customer service. Product arrived on time and as expected. Was easy to assemble. Boxes were even labeled. Only room for improvement that I could find was exploring use of a perforated plastic or adding a pull tab assist in opening the foam wraps. Either way, would certainly order again and already recommend to friends. Thanks.
My husband and I have had a sleep ez for 8 years and love it. We bought one for each of our children. The only problem is we are so spoiled it is hard to spend the night anywhere else but home.
We purchased an organic all-Talalay mattress based on our extensive online research. Our mattress arrived timely. It's easy to set up, comfortable beyond words, and has helped alleviate my partner's chronic back pain. Buy with confidence from this company; you won't regret it!
After 3 months my whife and I adjusted well to this mattress configuration. The support is excellent because the mattress normalize the body density and weight distribution in such a way that it countours the body profile in both side and back position; thus eliminating pressure points and spinal misalignment. The key is to align the neck during sleep patterns and the pillow supplied does just that. Other nicities include the adjustable bed that accomodate snore and other luxerious positioning. I'm well pleased with this design. Thx Langsy
Very pleased with my mattresses. And very, very pleased with the company. Easy to get a hold of real people there. Very helpful with all my questions. And went beyond the status quo to make sure I was satisfied. Thanks!
With our old mattress both my wife and I would both wake up a little stiff most mornings. With our new mattress that is no longer the case! We've been sleeping on it for about a month now. We customized each side, with one having a soft top layer and one medium. We experimented with switching sides and found out that the customization was definitely worth it because we both slept better on the side we thought would be the best firmness for our sleep position. We're well pleased with our purchase!
This is our second latex bed. We bought the king size to replace a queen bed. We will never go back to a traditional mattress. It is a little more work to put a king size mattress together due to the size, but worth it. Great communication from Sleep EZ regarding shipping. Thank you!
Bought this for the holidays. Had many very sensitive family members coming who can not tolerate non-organic mattresses. It was so well received that I may eventually move the mattress to the master bedroom!! Was very quick to receive. Arrived in pristine condition. Needs two to put it together, but its easy with four hands. So satisfied!!
We absolutely love our new mattress. We love the split side option! My husband and I needed different firmness levels and this was the perfect way to do it. The layer exchange process was smooth.
Great experience from ordering, delivery, set up instructions and phone support. Would not hesitate to recommend sleepez to anyone looking for a quality latex mattress for fair price
I have rheumatoid arthritis . Husband has lumbar DJD. it is the best bed ever! I have no pain. Husband's 90% better. It's on a adjustable base. GET IT!
So we were very skeptical to buy the first one. We lived in texas the showroom was in Phoenix we couldn't see it and we were hesitant to buy something we couldnt see or feel. Our son had allergies badly and all my research showed these didn't have that kinda problem and didn't off gas and other things. So we bought hte first one for his benefit. Its like a mattress from a 5 star hotel. We bought this config in case your wondering - Xfirm, Firm, and Medium. We liked it so much we changed our king bed as well to the same thing - those two are now 3 years old, we just bought another bed to replace our last remaining regular mattress. The only complaint if I had one is that there is a little bit of compression over three years where we mostly lay. Not super noticiable or anything but something, for that reason we rotate it (not flip) every 8-12 months. But other then that its PERFECT! we have a hard time sleeping on any other beds now!
My wife and I are sleeping longer and more sound than we have in a long time! Great innovation to be able to set up the firmness level of each side of the bed. We're both happy with what we chose!
I am chemically sensitive (but not allergic to latex). This was the perfect fit for me. Staff also very helpful.
Relieved a lot of back issues.. I’m very happy with my ourchase
We purchased 2 mattresses for a folding platform frame to use for guests. They are as comfortable as the 3 layer mattresses we purchased from SleepEZ 8 years ago. They are so comfortable that we wouldn't consider any other brand. The best thing is that you can move the mattress easily, because it comes in layers. I stacked the 2 new mattresses on top of an existing SleepEZ bed, and now our guests can sleep in a regular bed.
I love it 😍
Really, happy with my new mattress. Custermer service before the sale was excellent.
Setup was a little daunting at first because I’ve never built a bed, but it actually was quite easy! Very comfortable beds and very quiet when moving around on them. Great support from the team at EZ... I recommend the EZ bases and they also went together easy without tools!
I am chemically sensitive and have finally found a bed that has no toxic smell. I am quite happy and comfortable in my natural latex bed. The phone associates were friendly and so helpful. One slip up with an item not received was quickly remedied. So very satisfied with my bed and this company!
