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.
Suffer from tossing and turning? It could be because your current mattress doesn't support and align the spine properly. That's where Level's TriSupport™ technology can help. Level's technology is a marvel in zoned support with a high-end all-foam design made in the USA. While the shoulders and hips are relieved of pressure, the middle spine is supported properly. Ideal for back and side sleepers, the Level Sleep mattress is perfect for those that suffer from back discomfort and need long-lasting support. With a patented design and supported by chiropractors, it has been clinically shown to reduce morning stiffness.
Based on our aggregated reviews and our scoring method, we recommend Level Sleep in this match up!

We all need to take a look at customer reviews before we buy an expensive product. However , it can be a task extracting the key takeaways from all of the reviews you read. We did an examination of reviews and sentiment and discovered that sleepers rate these mattresses above average overall. However, some had disagreements about overall feel. Study more about the mattress specifics below.
These mattresses have above average ratings for support, which is ideal for those that are struggling with pain from a sagging mattress. That said, some people have reported that they don't feel well supported, so take a look at the firmness and durability ratings to ensure it works for you.
Edge support is a useful indicator of resistance and support along the sides of the mattress. These mattresses have good resistance, but some that are heavier may experience some softness.
Mattresses don't give sleepers the same kind of lasting comfort they used to. Finding a mattress that remains really comfortable after 15 years of use is definitely not a simple thing. But, finding a mattress that really lasts can save you thousands. These mattresses get mixed feedback when it comes to durability. Some sleepers don't have any issues, but others report having quicker than average durability problems.
Having highly rated customer satisfaction scores is a good beginning point to find if a mattress will work for you. Customers rate these mattresses highly when it comes to comfort. Customers report feeling comfortable with these mattresses and having a good experience with the company itself. Take a look below for the mattress specifics!
Everybody needs good support when you sleep, and these mattresses provide good, deep support for sleepers. Although you may think this means more firmness, supportive mattresses can also be medium or soft in firmness. The important part of support is whether it supports a healthy spine. These mattresses are excellent at aligning the spine and providing that kind of support.
Do you want to sit on the side of the mattress comfortably? These mattresses do well with providing even resistance on the side of the mattress.
Bowling Ball & Density Tests
Some reviewers measure mattress firmness with bowling balls. The most important part of this test is whether the dip is consistent and ideal for your body shape. These mattresses provide good density across the mattress for those that are looking for a comfortable and supportive sleep.
Making mattresses that really last for years upon years is a difficult thing for mattress brands. First, they would need to invest in better materials, and work harder on performing in longevity tests. Also, it can be difficult to know if there is a problem unless there are lots of complaints. That said, customers react very well to these mattresses based on durability and based on all of the data, should last up to a decade plus for most sleepers.

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'm a chiropractor and I have been looking for an orthopedic mattress for myself, as well as something I can recommend to my patients. I've had the TriSupport Mattress now for almost 2 weeks, and I am very happy with it so far! It successfully supports the spine's curves and is comfortable in all sleeping positions. I have noticed an improvement in my sleep quality too (fall asleep faster & wake up feeling more rested than before), which is an awesome added bonus. Stellar customer service as well. Thank you!View More Reviews
We upgraded to a king after having a queen, and couldn't be happier! This mattress provides amazing back support! I had just gotten shoulder surgery, and as a side sleeper needed something super comfortable for my back - no pain, and love may be converted to back sleeping!
I really love this mattress, it is very supportive in all the right places. The staff are very helpful.
For years I have had to put a wad of socks under the middle of my back to give me the support I needed to lay on my back. With this mattress I no longer need to do that. I also had issues laying on my left side putting pressure on my hip and making it feel out of joint the next day. With this mattress I have a lot less of that issue as well. I am very pleased with the purchase.
I noticed less tossing & turning the first night I slept on my TriSupport mattress. After a few more nights, I realized I wasn't snoring as much if at all! I like it's firmness and that I don't sink into it but rather sleep on top of it. It's comfortable sleeping on my stomach as well, however, I find I do not wake up on my stomach anymore because I'm quite comfortable sleeping on my back or side. I'm very happy with my new mattress!
The trisupport mattress is wonderful. The varied supports in the mattress lend itself for a painfree, relaxed sleep.
We were a bit apprehensive at first ordered 2 mattresses and couldn't be happier being a side sleeper my shoulders are in heaven sleeping better than ever Thanks
We have had our Level Sleep mattress now for one week and so far so good. It did take some nights (3) to get used to it and find the "sweet spot" for greatest comfort, but since then, we have slept great and have had no back trouble whatsoever!
we finally spent our first night in our new home on our sleep level bed. It was so comfortable. Jim said he felt very comfortable in all hia sleeping positions. I slept very soundly as well. I was going to send a note to thank the team for there great service.
This mattress and pillows are worth every penny. Have been have great night sleep ever since. Should have bought this month's ago. Thank you for everything.
I found Level Sleep through a friend and then was welcomed into their cozy Sonoma home store to one on for style. While the mattress in the store was amazing and is what prompted my first purchase for my new place; it was not until 30 days of incredible sleep that I appreciated the beauty of the TriSupport Mattress and Level Sleep's innovative technology. The stress of moving paired with other life altering events left me quite sleepless, but there was something in the comfort of my Level Sleep mattress that helped me sleep like a baby. More than 120 days in, my mattress continues to provide healing and restful sleep as promised. I am a believer! Thank you.
After swapping out my expensive mattress for the much cheaper Level Sleep mattress, I wasn't too impressed, but after a few nights I started waking up without my normal back pain (from my L5/S1 fusion area) that I had become used too. Maybe I didn't align myself vertically in the right position, but I really became a believer and a huge fan on the Level Sleep technology as it is the best mattress I have ever found for alleviating back pain. Way to go team. Great Mattress and a Great price too!
I've been struggling with back pain for years. My chiropractor told me about this bed and What a difference! The bed is firm enough to sit upright in as well as support you while you sleep lying down. It does not move around or disturb your partner like many other beds. I used to wake up every morning so stiff and sore in my previous bed. The price is also extremely reasonable! The bed came in the mail and was easy to set up
I'm so grateful my chiropractor suggested this mattress. For anyone who suffers with fibromyalgia, it is an answer to prayer. I also have a herniated disk & OA. This mattress provides the different levels of firmness/softness where they are needed most & I couldn't be happier.
I've been telling my friends about your intelligently made mattresses that we found to be very comfortable with support in the right areas. We've tried other mattresses that disappointed us rather quickly. We first put your mattress in the guest room and guests loved it, but then we decided to put it in our room and have been much happier than with our older, expensive yet sagging mattress. We recently stayed at Whitehall Hotel in Chicago that advertises as having the second most comfortable beds in a hotel....don't know what brand they use, but your LevelSleep is right up there if not better....
I am very happy with the level sleep mattress. I have struggled to find a mattress with the right support for my lower back that is also comfortable and good for the rest of my body. I appreciate this mattress has different firmness for different parts of the body. It seems to be working for me as I have been sleeping on level sleep mattress for three weeks and I have experienced good sleep and ZERO back pain. This is a welcome change from previous mattresses. On this particular mattress the sides are not as structured as ones I previously owned. I cannot sit on the edge without naturally sliding off the edge of mattress. Since I chose this mattress for sleeping this issue is just a minor inconvenience. I'm a mostly side sleeper enjoying pain free mornings thanks to this level sleep mattress.
I am so grateful for this wonderful product which provides pain relief for my autoimmune and osteoarthritis joint problems. I am now having a restful night's sleep and can more comfortably get out of bed in the morning. My quality of life has been greatly improved. Thank you to Zach for arranging to send it and the wonderful restore pillow to me in Melbourne Australia. My best wishes to all in the happiness team at Level Sleep. Christina Castles.
Great customer service. Delivery and packaging was easy. Mattress had no off gas smell at all. The cover is so high quality and breathable. Best nights sleep in over a year. Starting to see improvements in my neck and back pain after 10 days on it.
Before we purchased our mattress we had a couple questions about the product so we contacted the company to get more information. They responded right away and answered all the questions that we had. The were super friendly and informative. We purchased the king size mattress and have absolutely fell in love with it. My husband has back issues and this mattress has helped him tremendously! I recommend this bed to anyone looking to get an amazing nights sleep! It is totally worth the investment!
This bed is phenomenal. A must for spine care experts and their patients.
Recently bought a Level Sleep mattress when it was time to upgrade and we love it. My husband, who is an airline pilot, is sleeping better than ever. Just wish we'd bought them for every room!
Love the new mattress. It does what you said it would do - support the spine in the midsection and softer places for shoulders and hips.
I have a chronic lower back pain so I tried several other options before Level Sleep. And I can surely say that Level Sleep totally works for me. This is the first mattress which really relieves the lower back pain. I feel better even throughout the day. Thank you! I didn√¢‚Ç¨‚Ñ¢t think this was even possible.
I now have a total of three Tri Support Mattresses in my home and we love them! We were introduced to this product through a family member and at first we were skeptical and then when we received our first one...we were sold. We have had our mattresses for a few months now and there is no going back for us. Thank you Levelsleep!
We love the bed. My husband said this is the most comfortable bed he has ever slept on.
Both my wife and I were suffering from various pains upon waking every night. Since getting Level Sleep's premium mattress, we both have been waking up pain free. We love it! Thank you, Level Sleep!
I'm 92 and with the help of a 65 year old we had no trouble getting "THE BOX" up a couple stairs and on the bed. That was a couple months ago and so far we're very happy with the purchase.
And then my body adjusted to having lumbar support and my back thanks me every morning!
After the first night of sleep on my TirSupport mattress my back pain decrease by 80% when I got up the next morning. I am hoping that once my body adjusts to the mattress that my back pain will be eliminated.
I've been seeing my chiropractor for about a month with a back problem that was causing pain in my leg. After mentioning that I was having trouble sleeping because I couldn't find a comfortable position, he suggested looking at the Level Sleep mattress. After looking it over, I called with a few questions and ended up ordering a new TriSupport mattress. When it arrived, it was actually kind fun unpacking and setting it up. We've been sleeping on it for almost two weeks now and have definitely been sleeping better with less tossing and turning. My wife even said she thinks we're both snoring less now.
no back issues since Ive been sleeping on the bed- or shoulder issues.....used to have shoulder and neck stiffness in the morning and that is a non issue anymore. I think it would be best to have the special pillow also!
I had a bad shot mattress. I replaced with the tri support and have slept much better from night one. The mid support area is a little to close to the head for my baby. I have a twin. My abdominal part of my body is a litttle longer than normal and my legs area little short. I would have bought the longer and wider one but don,t have thes space.
I no longer feel painful back in the morning. Sleeping on my back seems to be much easier too. I really like it :-)
Very comfortable and good support but my arm always falls asleep if I sleep on my side. Is a less firm version available ?
I have slept better the past week than I have in the last year. The pillow is as much help as the mattress. I plan on getting the pillows for my children.
We started sleeping on our luxe mattress 2 weeks ago and couldn't be happier! We previously had a different brand foam style mattress that cost quite a bit more and we are much happier with the Level Sleep product! Thank you JJ and Zach for the awesome service!
I have questions and I want to speak with Zach. 213.595.5478.
So far so good I think it's a keeper
...a great night's sleep! This topper is amazing. From the very first night we slept on it, we were amazed how comfortable we were compared to previous nights. It arrived promptly and love that it was guaranteed to make us happy. It sure does. Highly recommend!
The TrSupport Mattress is great! We wake up without back pain. It's just the right firmness and it's really fun to sleep on; raise your head, raise your feet and use the wave to relax awhile before sleeping. Thanks to the technology team for the development of Level Sleep mattress bed. This mattress is made with high grade materials and will last a long time. We may go back and buy the mattress TriSupport Topper for days we want a change of pace to pamper ourselves. We recommend this bed to anyone who wants to Sleep Happy. Thank you.
