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.
Purple® mattresses are taking the industry by storm with their super lightweight polymer that is purple. It uses 'smart grid' technology to keep things cool and relieve joint and pressure point pain. Overall, they run a bit less firm than other memory foam mattresses and are rated in the medium firmness range, which is great for side sleepers. Some folks love the feel of this mattress, though there are others that prefer a more traditional feel.
Based on our aggregated reviews and our scoring method, we recommend Purple in this match up!

These mattreses have mixed emotions from buyers. Many sleepers report feeling comfortable with their decision and enjoy their new mattress, but there were others that didn't like their experience. Read on about this brand more below!
A supportive mattress that properly cradles the body is what you need for a better night's sleep. If you aren't supported by your bed, a mattress that properly supports you could mean deepers sleep and a happier you. All in all, these mattresses do offer good support at first, but some had issues with lasting comfort.
Most will find these mattresses to be fine for edge support, which is ideal for those who like to put weight on the side of the mattress. Those that have heavier frames may still find some discomfort while laying close to the side.
These mattresses get mixed feelings from sleepers on their durability. We all want to find the perfectly comfortable durable mattress that lasts over 10 years, but sadly not all mattresses last a long time. If you are considering buying a mattress with mixed reviews on durability, double-check the trial and warranty policies to make sure you are comfortable.
Most customers feel quite comfy with these mattresses and they gave them high marks overall. Some sleepers, however, didn't report feeling the same way. If you are considering one of these mattresses, make sure to read more about these mattresses below to make sure it will work for you.
Reviewers describe these mattresses as being supportive overall. Though there are some that don't absolutely love the firmness levels of these mattresses, most customers describe these mattresses as having the right amount of support.
Edge support is important for those that like sitting on the side of the mattress or like to lie close to the side of the mattress. These mattresses are well rated by most on edge support and they should do well for most customers.
Bowling Ball & Density Tests
Bowling balls are useful to measure mattress firmness and support. These mattresses are above average at providing even support, which means they should cradle your hips and shoulders while aligning the spine.
It is a tough prospect to find great products that last a long time. Brands, for the most part, rather make recurring money than craft something that can never break. However, there are still great products to be found. These mattresses provide a very good element of durability to most sleepers. Most folks will have them last between 7 - 12 years, though some who are of bigger builds may experience that they will degrade a bit faster.
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 read and watched multiple reviews and was a little skeptical about if this mattress would be a good fit for me. I decided to give it a try, and am so happy with my decision. I have only been able to sleep on it a few nights, so I can't speak to long term satisfaction, but just the feel of the mattress is so unique and comfortable. Every time I pass by my bed now, I can't help but flop on it and lay there for a few minutes. If you are on the fence about trying the mattress, I would say go for it for sure. The only disadvantage that I've noticed so far is that it is near impossible to get out of bed in the morning. I was a few minutes late to work the last few mornings because I did not want to leave my bed. When I was reading all the reviews, I heard that purple fluffs up their review page to make their mattress look better. After trying this mattress, I do not believe that is true. I believe that people genuinely love the product and want to share it with other people. I am not typically one to go out of my way to write a review, but this product is incredible so I felt compelled to do so. Obviously everyone is different so you may not have the same experience I have had, but if you are on the fence and looking for a great mattress, give Purple a try.View More Reviews
It’s been an OK experience. We had a very old mattress so when our Purple mattress arrived and we tested it out the difference was big. The major good thing is that I don’t feel my husband moving and turning around anymore. That’s great! But other than that I can’t really say it’s an “out of this world, amazing mattress”. We were also disappointed cause we bought it just before thanksgiving and we asked them to check if a Black Friday sale was going to take place. No one could inform us anything so we went ahead and bought it with the current sale. We were very disappointed to find out on Thanksgiving Day that the sale at that time was the free Purple Blanket + $100 discount. We called and they couldn’t honor us that so that was a bummer.
I don't know when we purchased this mattress. I think if I were a back sleeper, it might be good, but I sleep on my side. This mattress does not allow enough give at the hips (contrary to pictures showing the spine in perfect alignment). So, my waist is pulled downward causing discomfort and constant shifting and readjusting. I think I slept better on my 20 year old mattress. I actually hope we can return this mattress and get something else. Would hate to have a mattress that we paid hard earned money for and can't stand to sleep on.
Every morning my wife and I would wake up with back ache's from our old mattress. From asking around my chiropractor said many of his clients had tried the purple mattress and really liked it. We decided to purchase one and it is great. Nice and firm. We sleep much better at night and feel great in the mornings now.
terrible experience bought purple products some showed up, some didn't and purple customer service sucks they don't reply and have been no help what so ever. terrible experience.
We have not noticed a difference in back pain just yet but we do notice we don’t want to get out of bed in the morning due to the mattress being so comfy.
A gift for my pregnant daughter. She says PERFECT!!!
Once I got a few adjustments from my chiropractor and slept on my new purple mattress I haven’t had any back problems since. I’m very satisfied with my results.
I love this mattress. It is now my favorite place to be. So comfy and cool all night long.
I’m a big fan of everything but the bed. I love the pillow, the sheets, the driving cushion. 10/10 for those. The mattress is terrible. No matter which way I sleep I’m always waking up with lower back pain and I never realized it was the mattress until I started sleeping in hotels and waking up pain free. It’s 1000% the mattress :(
I am not going to buy purple products again. I got the mattress which was advertised as being long lasting but after a few months it has obviously gotten worn in. It started to feel like crinkled plastic after less than 3 months and I thought about returning it but got lazy about it. We also got the purple mattress cover but the first time the baby wet the bed it went right through the cover. Mattress cover useless. The bed stand commercial shows sumo wrestlers fighting on the platform, but when mine showed up the holes were drilled in the wrong places by about a 1/4” which made it extremely hard to put together and 6 months later the metal bangs from warping and being pushed around by my weight. I spent a lot on this bed and all the great features advertised were hype and lies.
After hauling this heavy thing up two flights of stairs, my back was killing me. I unpacked the mattress, laid down, and within 5 min, my back was feeling great! I have had the Purple mattress now for more than 2 weeks, and I’ve had wonderful sleep and zero back pain. I need a firm mattress for my lower back, but as I’ve gotten older, a traditional firm mattress hurts my shoulders and hips. The Purple supports my back while it forgives my pointy bits. I love it! Can’t recommend it enough!
I am still deciding I fall asleep well but have been waking up with back pain pretty intense not sure if it’s the mattress or what yet
I'd had my old mattress for 15 years, and knew I needed an upgrade. I compared over a dozen different mattresses before going with Purple - the reason I selected Purple was because of its new and unique technology. I'm so glad I went with it - it's so supportive and comfortable. My partner had trouble adjusting (side sleeper), but after about a week, he is well-adjusted and sleeps like a rock! The only issue I had is that the queen-sized mattress is definitely more than 100 lbs, but on the site, it's advertised as being less than 100. It was *extremely* heavy, and difficult to move once it's out of the case, but its level of comfort and support makes up for it all.
Slightly firm but the softness feels luxurious
I can’t reqlly say more than this bed is amazing. I have had it for two weeks now and sleep better than I ever had before
This is my second bed with purple and both times I have been more than pleased. I’ve never slept on a more comfortable bed or dealt with better customer service!!
I have multiple back issues including stenosis and bulging discs as well as osteoarthritis. By far the most comfortable bed I have ever slept in. I look forward to going to bed at night. It is now my haven. From couch potato to purple potato :)
I wish that I could write a review on the item that was suppose to be here last week but I haven’t received it yet. When I emailed purple they took almost a week to get back to me with a ****** nonsense answer that they ran out of material and would need another 1-3 weeks to make my mattress then they would have it shipped. I’m 8 months pregnant and sleeping on an air mattress because they ran out of material. Don’t ever buy from this company. You will be waiting months to receive your product with no communication from the actual company!!!
I love the color purple anyway but this mattress has changed my life! The best sleep I have had in 10 years! I'm getting them for the entire house!
...but so far it’s been great. A mattress is a long term relationship though so what really matters is how I feel after a few months. So far I really do love it, but I was sleeping on garbage before. Trust me, I’ll edit this review later if my opinion changes.
I had high expectations.... you’ve exceeded them.
I gifted this to someone, and they gave it the best possible rating !
Within 2 days of sleeping on this bed my neck and back pain was non-exsistent. I could sleep for 5 hours and wake up refreshed. It's been a month now and I am soo happy with my purchase..
I wanted to support a local Utah company and was so excited to receive this mattress but this was a huge mistake. The quality of this mattress felt like a blow-up mattress that should cost a fraction of the price. For me (skinny guy sleeping on his stomach) it was just uncomfortable and felt weird. To be fair I've heard others say they bought it and like it but for me it was laughable to see what I received for $1200. I also bought the purple mattress protector and it feels like plastic compared to my previous one. Be careful because they won't refund the mattress protectors so I wasted about $70. Buyers beware!
I can’t believe how awesome this bed is! I did lots and lots of research and decided to get the Purple bed and I’m so happy I did! I have never slept better! Super happy with the bed!
First off, the king sized mattress does not fit on our king sized bed frame. It hangs off the foot of the bed and the slats show on the sides. Ridiculous. Never had this issue with any other bed. The waffle pattern feel isn't exactly soft and comfy either. Still we gave it a try to see if we got amazing sleep. It wasn't for us. I thought the returns process would be simple like Casper's. I called and the wait was long so they called back. Then instead of processing the return then and there like Casper did, I had to get an email and submit a return form. And then we'll see how the rest of the process goes. Also note that when you buy the mattress there is usually a free promo item. When you return the mattress, you cannot return the item so you are charged full price. There should be a note when you select the promo item to remind customers of this fact. I would have selected no gift. But I guess by being shady, Purple ensures if you hate the mattress, at least they sold you $130 sheets.
Let me start by saying WOW. I have been sleeping on a Nectar mattress for a while. Every morning I would wake up to lower back pain that would go away after 30 minutes. I blamed this on being 51. The first night sleeping on the Purple I woke with no back pain. My wife had back surgery 2 and 1/2 years ago she says this is a game changer. My only regret is not ordering this sooner and not ordering the pillow. PSA the sheets are also amazing.
Hands down the best mattress. If Purple contacted me and said I needed to pay $300 more to keep the mattress I would rather pay it than give it up. The best investment and purchase I’ve ever made. My partner says the same thing!!
I work 2 jobs, about 55 hours a week, and am on my feet 95% of that time. had lots of trouble sleeping thru the night until the Purple mattress came along. in 3 weeks, i have slept amazing. even slept thru my alarm 4 times!
This thing helped me rest on a whole nother level i will definitely buy another one when this one is of age.
Me and my fiancé absolutely love this mattress. We’ve slept so well since we’ve got it.
Loved our Purple mattress so much we decided to allow our guests to experience this great mattress as well.
This mattress is absolutely life changing! I suffered back pain and haven’t slept well in years! The purple mattres has changed my life. I sleep like a baby and have no back pain at all!
I was definitely skeptical about buying a mattress online, but with the return policy I figured I would try it. Best idea ever! I’m such a light sleeper, and I no longer get woken up when my husband is restless or the cats are jumping all around. Plus, it’s so comfortable!
I got the wrong size mattress and while I appreciate their willingness to do an exchange, the process has been liborious. The product itself is quite nice for the price. Thank you.
I’m a prominent side sleeper and was consistently waking up with shoulder and back pain. This new mattress solved those issues the first night I slept on it. I would definitely recommend it to anyone.
Feel like I'm falling out a bed wake up !with a back ache
This mattress is perfect. My wife and I both used to gravitate toward the center of our old mattress, where it caved in, and wind up fighting about which of us was on the other's side more. This isn't a problem anymore! We like sleeping together again! She even hooked up the TV in the bedroom! We're never leaving this bed. Seriously, it's great. It isn't hot. We can't feel each other move at night, which is good for my wife because I move around more than two pigs fighting under a blanket at night and now I get yelled at a lot less on the whole. Money well spent!
Aligned both mine and my boyfriends back and helps us stay cool and sleep throughout the night rather than walking up every 3-4 hours like we use to on our pillow top. I’m a stomach sleeper and he’s a side sleeper, neither of us can complain about anything anymore. It’s more firm than expected, but I actually enjoy it over a soft memory foam mattress.
