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.
Maxim mattress is a California based mattress company that has been building innerspring and hybrid mattresses for the past 30+ years. They are well priced and offer a good variety of different mattresses for the budget conscious shopper. In terms of comfort, most find these mattresses comfortable, but some had concerns about durability and material quality.
Based on our aggregated reviews and our scoring method, we recommend Diamond in this match up!

Understanding customer satisfaction can be a big win in finding yourself the right mattress, but it isn't always as easy as it seems. Overall, these mattresses get mixed feedback. Some folks describe a very comfy sleep, but others were restless and didn't feel comfortable. Read on to learn about the mattress specifics and hear from customers.
Mattress support is one of the most important things to stomach and back sleepers. Also, deeper support can be a make or break for side sleepers who need response but are at risk for back problems. These mattresses provide sleepers with above average supportiveness. That said, some folks didn't feel supported enough so if you are heavier, make sure to read the reviews.
Most agree with the edge support of these mattresses. Some folks may experience some sagging when sitting or laying close to the edge.
A mattress that is good for durability can save you a lot of money and headaches. Sadly, in this day and age, everything from bedding to clothes degrades faster. Customers give mixed feedback when it comes to the durability of these mattresses. Each bed is different so it may last years for you, but others may not be so lucky. Make sure to take look at some of the customer reviews to see if the mattress should work for you before purchasing.
Some customers are happy with their mattresses, but others are not as happy and have had complaints about comfort. Despite those that are completely satisfied, this brand has lower sleeper satisfaction scores than the average. If you are considering one of these mattresses, make sure to read on for more information.
Support isn't the same as firmness. Excellent support means having a mattress that cradles your hips and shoulders to align you back. Overall, these mattresses have had some mixed reviews when it comes to support. Most customers are comfortable with the support right after purchase, but some have reported support issues as time as gone on.
For those with mobility concerns or like to lay close to the side of the mattress, edge support is very important. For most, these mattresses do a fine job with edge support at the beginning, but some found that it wasn't as supportive as they'd like
Getting a mattress which has lasting comfort is what buyers are after. We all really want to find a bed that will be comfy a decade or more later. Unfortunately, not all sleepers have felt that these mattresses were durable enought for them. If you are looking to use one of these full time, read the reviews to make sure it will work with your body before buying.
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.
Best quality, best customer service. Been working with this company for years! They are a wonderful company who stands behind their product and truly cares about the customer's needs. I reccomend them to everybody!View More Reviews
Bought my mattress from Just Like Home furniture in Tarzana. We purchased a Blue Mist, the manufacturer is Maxim Mattress. WOW! I LOVE MY MATTRESS! Thank you Maxim for such a great nights sleep!
Highly recommended to buying maxim mattresses, lowest price with high quality, after I got this mattress my pain already said goodbye to me!!!!!
Being an Asian, it is common for us to sleep on very firm beds. When I first moved to the US, it was a pain looking for a firm mattress which was affordable at the same time. I went to so many stores looking for a cal king firm mattress with a budget of $800 and it proved to be impossible until I saw the reviews from Yelp on Maxims Mattress.
I went to Maxims Mattress and the showroom is nothing to shout about. It looks like a typical warehouse. Turns out, they manufacture mattresses too. The people at the store were straightforward about their products. They were not pushy. I just had to tell them exactly what I was looking for and my budget and they sold me a cal king firm mattress for $700. It was a brilliant deal. I could check out their stock, pick the mattress and they helped tie up the mattress on my ride. I saved on delivery charges and brought home the mattress that day itself. The whole process of purchasing the mattress and having it tied on my ride took less than 30 minutes.
Since I share the bed with my American boyfriend who likes his bed soft, we compromised and bought a 2 inch memory foam topper from Target and we now agree that it is the best bed ever. It is firm with a slight plush. No more backaches for us. In fact, we get backaches when we sleep on other beds. The next time we move, we are definitely bringing this mattress with us no matter what. Best investment ever.
I also went to Just Like Home furniture since they carry all the Maxim mattress models and they were so helpful and offered the best customer service and pricing!
Worst mattress ever! We purchased a mattress from this place. Both my husband and I have developed back pain. We wake up with pain to the point that hour limbs feel numb. We don't experience back pain when we travel or sleep on another mattress. We have ordered a new mattress after only five months of purchasing a Maxim mattress. I can't wait to receive the new one. I don't recommend this brand at all.
I bought a king size mattress a couple of years ago at first it was good but after about a year it started getting lopsided my wife's started complaining about back pains and I felt the same way so we contacted maxim and they said it was past a year so I had missed the warranty by two weeks I guess my bad but if you pay $800 bucks for a mattress it should last at least 3-4 years I learned my lesson I just went to sit n sleep they gave me 3 years and there just down the street on telegraph rd ask for Johnny he's good people!!!
I purchased a king size mattress from maxim Cony and they send me a California king size which does not fit my bed. The most ridiculous thing is they ask me to pay extra $50 for the second delivery. Which means I am paying extra money for to fix their mistakes. They should have compliment my delivery at all. Poor customer services! Irresponsible for their own mistakes. The delivery guy told me their king = California king!?!Why wouldn't they confirm the measurements before selling but instead they sell / push selling people what they already have in stock and ask the customer to suffer for the delivery cost if there was internal mistake made within themselves. Very poor sales skill and after sale service.
Not convinced of the quality of these mattresses. Wasted over $1,000 on a mattress I purchased directly from the company. It sleeps very hot and the bottom is covered in a fragile, almost paper-like fabric that easily rips. The sewn seams are also fragile and easily ripped. Not sure why one would spend money here when there are plenty of quality, inexpensive online retailers that offer generous return policies.
Oh yes I bought my second mattress at maxim mattress there warehouse in City of Commerce and its My 2nd mattress I get from them I am a native of Los Angeles California leaving now in Montebello and I am overwhelmed with the quality of the mattresses from this company is it it's just one of a kind it's quality. The service I gave him between 1 and 10, they get them at 10 for their honesty me and my wife are really totally over satisfied with their mattress I actually give them a five star and I hope they never go away because I always get my mattress there thanks thank you thanks to Connie it's a family business they do an excellent job thank you very much Jose your loyal customer
Bought a mattress with box springs manufactured by Maxim. At first, I was very satisfied and loved the feel of the mattress (perfect blend of firm but soft). Less than 4 months in and the box spring made so much noise, we sought to have it refunded. The store we purchased from stated the manufacturer was out of business and someone else was taking care of their warranties. I had a lot of issues with the store I purchased from following up on my request for exchange under warranty. Six months later we finally received a new box spring. At this point the mattress started to collapse on both side and the edges bulge out. The new box spring now makes the same noises as the old one. Save your money and steer clear of their products.
We love selling Maxim Mattresses at our business - WEST COAST FURNITURE OUTLET. The quality is superior to all other mattress brands. It is a great feeling knowing that our customers are always pleased with their mattress sets from Maxim. The sales rep Mario is always helpful with any questions we have. The company owner is also super friendly with the customers. We really enjoy doing business with a mattress manufacturer that is run in such an honest and caring manner. Thanks!
You've been warned. Do not buy a Maxim mattress, as you will regret it. Six months and nearly $1,500.00 later, my Maxim mattress was concaved and I was sleeping cocked. Their distributor sent me to them, where their customer service was non existent, zero follow up, and even less help on warranty or repair assistance. Being a small business owner myself focused on customer satisfaction, it disgusts me that they claim this on their website.
Great value for the buck. Better than Kluft/Airloom at fraction of the price. I highly would buy this product anytime I'm in market for another mattress.
A review, long overdue! I purchased a Maxim mattress - Island Bamboo Mattress, 2 years ago and it is still super comfortable! Naturally I came back with my mom, to purchase one for her! Another great quality mattress! Highly recommend!!
