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.
Purasleep is an affordable online mattress company popular on Amazon for selling memory foam mattresses. Their foams are CertiPUR-US certified not to offgas and they offer different firmness options for various budgets. Most customers find their mattresses comfortable, but some had issues with durability.
Based on our aggregated reviews and our scoring method, we recommend Diamond in this match up!

Many folks don't report any issues, but others have comfort problems over a shorter time frame than is usual.

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 will support you for the long term. If you are thinking about buying a new mattress that isn't an A+ on durability, make sure to take an extra look at the policies on return to make sure 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 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
This bed was perfect and everything I'd hoped it would be... at first. After having if for a few months it seems like it's wore down in the middle of the bed where I tend to lay more often. If I try to lay on the edges I just roll to the center. It seemed to good to be true at first, but I don't think they're built to last.View More Reviews
I feel like it already may be sagging in the middle since that is where I sleep the most, but is very soft and comfortable
I waited a long time to write this review because most beds are great when you first get them. But there are huge sleep indents where my wife and I sleep, and one big raised lump in the middle of us. I'm a big guy over 250 pounds, but my wife is barely over 100 pounds. I understand how my side has been messed up, but not hers! Now after 18 months of sleeping on the mattress it is way too soft and way too lumpy and we are searching for a better brand.
I wanted a memory foam mattress for years after sleeping on one on a hotel. I refuse to pay $3000 for a mattress. I bought this after reading the reviews. I have had the best several months sleep ever. I don't wake up sore anymore. We did not experience any of the smell reported in other reviews. You absolutely cannot beat the price!
The mattress arrived timely. We let it rest a couple of days before using it on the bed. There was little to no off-gassing smell and my niece says it sleeps very comfortably. Very good purchase! Thank you.
When I see this in the Amazon Primeday, I said to my self 'I Want One Of Those'. I have full size bed frame that needs a bed mattress. As advertised, a full size is measured 75 x 54 x 10. I like as it is 10 inch thick. Ordered a full size, got it. packaged like a vacuum seal, it is heavy . Opened and placed it on my bed frame. And now I said to my self, Oh! NO!! S....!!!. It is wider than it is advertised. It is 56 inch wide, and it won't fit my bed frame. Mattress is firm and has a nice cover. I will return it and now my problem is re-packing it back to its box. Maybe return it in several pieces. Very dissappointed
This mattress was a steal!! I was so skeptical due to the low price but I am SO happy I ordered it anyway! It's firm, yet soft. Excellent quality. I've never slept so well. The only downside is being so comfortable that it's difficult getting out of bed in the morning!
so easy to set up. SUPER comfortable. My husband who is in chronic pain from just being a dum-dum when he was young sleeps better on this than any bed we have ever slept on.
Wow, I love this mattress. Just a fair warning, I never owned a memory foam mattress before this 1 so maybe I'm just too biased towards it. It's firm enough to support me sleeping on my back and soft enough for me to sleep on my side with no issues. It supports edge sleeping very well not that I like to sleep on the edge since I tend to fall off my bed when I do lol. The only thing I really really really disliked was the VERY strong smell coming from the mattress when you first unwrap it. Highly recommended you let the mattress air out for about 2 days. After I've done that I haven't smelled anything coming from the mattress.
I used to have insomnia. USED to.
The mattress is great I would say up their with the serta i comfort line and without the high price.
The mattress has great support for the body and even has edge support and does not heat up like other memory foam mattress.
I am not really a one position sleeper and have no complainants unless you want a extra firm or a ultra plush mattress as I would rate it the sweet spot.
I love this bed. I was a bit skeptical initially as I have never purchased a bed without actually going to the store, however I did a little research on the company and made the purchase. I am very happy with it. I look forward to purchasing another one when I have a place to put it.
It was hilarious seeing a queen size mattress come out of that (relatively) tiny box. It had hardly any 'memory foam' smell out of the bag, even less after letting it sit for 24 hours. Very comfortable, but one of the firmest mattresses I've ever slept on. If you don't like a very firm mattress this might not be the mattress for you.
Good mattress for the price. Hard to tell if it will hold up over time. Edges a bit soft.
I received what appeared to be used mattress with oil on one side and tears on the other.
We have had the mattress about 3 weeks and it has exceeded my expectations. My old mattress was very expensive and it was never this comfy. I always woke up extremely hot and sweaty,so you know my concerns about switching to memory foam. I'm soooo pleased ,cool and rested. LOVE IT!
This bed is firm. If you like a firm mattress, you'll probably love this one. Personally, I expected more shape contouring from a bed this expensive. To find out why it's not great I unzipped the top cover to discover it is simply an 8-inch piece of upholstery foam with a 2-inch piece of memory foam glued on top. That's it.
On the plus side, the cover is stretchy and seems like relatively good quality except for the fact that it has a part where it wasn't sewn correctly and is falling apart along 2 inches or so of the seam. My wife likes (but doesn't love the bed). I am sleeping OK, but find it uncomfortably firm. I've gone ahead and put another 2 inches of memory foam on top of the bed and I'm hoping it will soften things up to my satisfaction.
Another positive feature is that there was very little odor when we opened the package and it dissapated quickly.
