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.
Leesa is a popular foam mattress company that makes its flagship Leesa mattress with three layers of foam -- one layer of LSA200™ cool foam, a memory foam layer, and a last support core layer. Their mattress is well loved by many customers and they have a positive company mission, donating 1 out of 10 mattresses to non-profits who help the disadvantaged. As one of the first brands riding on the mattress-in-a-box wave, Leesa has made a big name with thousands of happy customers. Live in the UK? See our review for the UK version too.

Each of us want to see customer feedback before buying such an expensive product. However, it can be hard to distill the takeaways after browsing countless other sites. Based on our examination of sleeper reviews, we've found that customers give these above average marks on overall satisfaction. However, some had disagreements about overall feel. Make sure to read on for added specifics.
Stomach and back sleepers need tons of support from their mattresses. Side sleepers also need a supportive mattress that keeps their spine, hips, and shoulders aligned. These mattresses provide sleepers with above average supportiveness. That said, some folks didn't feel supported enough so if you are heavier, make sure that your selection is right for you.
Most customers like the support in the edges of these mattresses. Some, however, had some complaints about the support.
Mattresses don't last as long as they used to in years past. For those that are looking for mattresses that last over 15 years, these days it can be hard to find. Yet, finding a mattress that really remains comfortable that long can save you lots of money. Unfortunately, these mattresses get mixed reviews on durability. Many sleepers don't report issues, but others have complaints about durability over a shorter time frame than usual.
Having excellent ratings from sleepers is an important factor for shoppers. These mattresses get higher marks from customers than many other competitors, which should give you a good foundation to finding out if they will work for your preferences. Learn more to see if these mattresses will work for your body!
Having quality support materials is essential to the comfort of a mattress and whether it enhances the natural curvature of the spine. According to most reviewers and customers, these mattresses are good at supporting sleepers. So, you can rest easy that these mattresses will support your back while you sleep.
Most customers report that they are satisfied with the edge support of these mattresses. This means that you'll feel the same amount of support on the sides of the bed as the center and the mattress will give you additional surface area to sleep on.
Bowling Ball & Density Tests
It's popular to test support by resting a bowling ball on the top of your mattress. Overall, these mattresses do well at keeping consistency across the mattress without many complaints, which is is a good selling point of this brand.
It is a hard thing to find great products that last over 10 years with constant use. Brands, for the most part, rather make repeatable revenue than make something that lasts a lifetime. However, there are still pack leaders out there. These mattresses, for example, do a great job with quality and durability. Most sleepers will find them to last between 7 - 12 years, though some who are heavier or use their mattress more often than nightly may experience them faltering sooner.

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
My wife and I live this bed so much. When we don’t sleep at home we miss it. Very sound sleep every nightView More Reviews
Was pleasantly surprised with the support, comfort and overall better sleep provided by this mattress. I had a spring mattress for over 8 years and decided initially to go for a hybrid construction of spring and foam. This hybrid option eventually did not work out and I went with the all foam solution. All my initial worries were gone after that first night, the mattress does provide a good level of support and dissipates heat quite well. The only down side to this mattress was the smell it had for about a week after unpacking it, not a terrible thing to have to deal with for some days but not pleasant either. Regardless, I would highly recommend this mattress.
I bought the queen size mattress. It was delivered promptly and weighed 74 pounds. It wasn’t too hard to move around or dump out of the box (I have a low platform bed frame). Did a little adjusting of the cover or it would have opened lopsided. It is wonderful. It is supportive. There are no pressure points to cause pain anywhere on my body. I sleep with less tossing and turning so I’m more rested in the morning. I love my Leesa. Best $800 I have ever spent.
My Leesa is amazing. My back feels so good when I wake up in the morning (not always the case on other mattresses). I love memory foam but hate how hot it makes me feel and Leesa seems to have solved this problem. It reminds me of memory foam but I never overheat. And I don’t notice my wife getting out of bed in the morning. I paid a lot more for a Sleep Number and am replacing it with my Leesa!
Love this mattress! Firmness is perfect! I researched for a year and glad I chose the Leesa.
Going to bed has become one of my favorite times of day as a result of the Leesa mattress! Nicest bed I've had the pleasure of sleeping on!
I love the two Leesa Mattresses that I just bought. I now slumber in a deeper sleep. I don't wake up during the night tossing and turning, and look forward to going to bed! The pillows are fantastic. .
I love it. The best night sleep with out waking up stiff. It is very relaxing
We love our mattress! You sink in at all the right pressure points. We both especially like how our hips are sinking in just enough. It’s not slow to form like other memory foam beds, so when you roll over, your not leaving a hole and sitting on top. Our only complaint and the reason I didn’t give 5 stars, is the smell. During the first 2 weeks, it was pretty strong, it’s been about 2 months and it’s finally gone away for the most part. I’ll occasionally still smell it. I imagine all foam beds have this smell.
This is a very firm mattress. I wish there had been an option to choose a softer one. Also, deep-pocket sheets, which most new sheets are, do not fit well. They are much too big.
My whole experience with Leesa has been wonderful. I ordered the mattress and foundation and had the mattress two days later! The foundation takes a little longer but I had that within a week. There was very little off-gassing and I didn't find the smell offensive. I'm very sensitive to smells/fumes, I have asthma, but we were able to sleep on this bed the very first night. The mattress is THE most comfortable thing I have ever felt! It somehow manages to cradle you, like a big, soft marshmallow and provide the perfect amount of support. I suffer from multiple sclerosis and fibromyalgia and this bed has made such a huge difference in my life. I no longer wake up feeling like I've been beaten-up and while I rarely sleep through the night due to my illnesses, the rest and sleep I get on my Leesa has greatly improved my life. I've honestly never experienced this level of comfort! Thank you, Leesa!!!
totally awesome comfort after 6 weeks. Love it.
Best night sleep that I have had in a long time. The only downfall on this mattress is I never want to get out of bed!
I don't know why we waited so long
My wife and I LOVE our mattress. But that begs the question, how do you know you love it? First of all we aren't complaining about how we feel when we wake up anymore. We don't talk about buying a new mattress or even considering making a change. We fall asleep, and stay asleep (except when our 5 mo old wakes us). It's become a wonderful part of our evening, most nights I look forward to lying down! Great mattress for the price.
relieved that it's as good as the reviewers make it out to be and relieved that i turn much less than I did on a spring mattress. My wife's experience is the same. It's a deal.
We bought a king size Leesa for our master bedroom and loved it so much we bought a queen size for our guest bedroom. Our guests are going to love it!
I have to admit I was a bit skeptical that a mattress that is not super thick could be comfortable. My husband and I were both pleasantly surprised. The mattress has been wonderful. Not too soft, not too firm. It is well made with a beautiful cover. Love my new mattress
Best mattress yet
nice to finally get a good nights sleep.
Fell in love on the first night and have slept better since. It is the right amount of firm and soft and cannot tell when my husband moves next to me. I am a Leesa owner for life!
I am enjoying this mattress
I enjoy my mattress and will buy again in the future. Bed feels firm but contours to my back. It has lessened my lower back pain. Only gripe is that the mattress has a plastic smell upon opening that lingers. Had to leave windows open for a week to let it air out. Smell is still there but faint.
I love the matress and sleep great. It provides great support and breathes well. It still has a slight chemical smell from then it was made I guess but you get used to it.
Only reason I don’t give 5 stars is, LEESA tell us there may be some “off gassing” from the mattress for a few days. That means fumes emit from the mattress’s man-made material, a kind of settling process.
In the case of my mattress, it was like sleeping over an open can of paint for over a month. Then the “gassing” finally stopped.
I sleep really well on this mattress. Glad I bought it.
I'm a stomach sleeper and this mattress was too soft for me. I needed a mattress that was a bit more firm.
Our mattress has already developed troughs. It's still comfortable enough but there's no way it will last even 3-5 years, let alone the 10 a mattress at this price point should last.
We bought the leesa for our Special Needs son. He is 35 and has a hard time sleeping. He has loved it. Sleeps so much better and is in a lot less pain when he gets up. Thank you.
My husband just had back surgery and he has been loving the Leesa mattress. We both think it's wonderfully supportive and just the right amount of soft. We love it!!
Delivery and packaging was quick and easy. The light smell it had only lasted a day or two. As a heavier set guy, it felt amazing. It was super quiet, unlike a spring mattress. Very little disturbance with my wife. My wife on the other hand, hated the mattress. She's considered petite, and the more dense nature of foam mattresses meant she felt the Leesa to be a lot more firm than our last mattress. Sadly, I ended up returning it for her. It's a great option for medium to large folks. By the way, the return process was a breeze and refund processed about 5 days after the pickup. Amazing service.
My fiance and I are about a year into our Leesa experience and for both of us, it's been the greatest investment. She and I both travel extensively and we sleep in a lot of hotels but no matter how much we enjoy the mattress, we always look forward to coming home to the Leesa.
Super soft and well made mattress! We have been impressed with the quality and how it’s almost impossible to have a bad night’s sleep on it. It does run a little hot but I’d imagine not as hot as other memory foam mattresses due to the Leesa’s thoughtful construction.
I have gotten the best sleep ever! I’m a back and side sleeper and it’s been amazing for me! Definitely worth the investment! If you’re going to buy a mattress that will last and will allow you a great sleep, go with LEESA!!!
comfortable and supports my back well while being comfortable
Bought this mattress for our son, he is a very big boy, hoping the mattress won't start sagging in hot e middle as every other mattress we have bought for him! We will see!
I've been having difficulty sleeping due to a injury. I purchased the Leesa mattress and was finally able to get a decent night sleep.
After sleeping on this mattress for over a month, I’m ready to review it. This is by far the most comfortable mattress I’ve slept on. I also upgraded from my queen mattress to a king, which has been excellent. Along with the great sleep I’m having throughout the night, I’ve noticed I no longer wake up when my husband adjusts or gets in and out of bed. Experience with this mattress has been great!
For me, the Leesa Mattress has proven to be a wonderful mattress. I have bursitis in both hips; I have had zero hip pain with this mattress. I sleep soundly, comfortably. If my kids hop into bed with me, they can move without disturbing me, and vice versa.
I highly recommend trying this mattress. What price would you put on a peaceful night's sleep?
