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.
Sherwood Bedding Group makes a variety of mattress brands including Sherwood Bedding, Lumina, and Encore that are innerspring, pocketed coil, and hybrid mattresses. They also make Evosleep and Dunlopillo, which are memory foam and latex options. You may find these mattresses in local retailers such as Mattress Firm. Folks describe them as comfy in store, but may experience durability issues once at home.
Based on our aggregated reviews and our scoring method, we recommend Diamond in this match up!

Some reviewers report loving these mattresses, but others haven't had as great feedback. Overall, these mattresses are rated well, but with some caveats. Read on for customer reviews and the specifics.
A supportive mattress that properly cradles the body is what you need for a better night's sleep. If you have a bed that doesn't support you, you simply won't sleep as well as those that have a mattress that aligns the spine. Most customers were happy with the support from these mattresses, but some had issues with the feel.
Most find the edge support that these mattresses provide to be good, which is good for those that enjoy sitting on the side of the mattress. Some folks that have larger builds may still experience some dipping along the sides.
Mattresses don't provide as long-lived comfort as they used to. Finding a mattress that remains really comfortable after 15 years of use is definitely not a simple thing. However, finding a mattress that really stays cozy that long can save you lots. These mattresses get mixed feedback when it comes to durability. Many folks don't report any issues, but others have comfort problems over a shorter time frame than is usual.
Discovering how folks really feel about a certain mattress is sometimes a hard thing -- especially with all of the great marketing that is being done to capture people's attention. Customers, unfortunately, don't always feel great about these mattresses. There are still folks that are content, but others who are really not. Read on below to get the details on the specifics.
Overall, these mattresses may leave something to be desired in terms of lasting support. Though some sleepers find these mattresses to be comfortable, others don't like how they work with their body. If you like these mattresses, make sure to look at the specifications to make sure it will agree with your body.
Overall, edge support is extremely important to those with mobility issues. Others don't find it is to be a big concern. These mattresses may not be perfect when it comes to edge support so make sure to do added reading if it is an important item for you.
These mattresses may not provide the kind of durability that you'd hope. On a shorter than average basis, some sleepers have reported feel and durability issues. If you are larger or are looking for something supportive, one of these mattresses may provide initial comfort, but do some added reading of customer reviews before purchasing.
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
SO SO SO disappointed in the futon mattress we purchased along with a futon frame- which is just o.k. But I specifically ordered the highest end mattress thinking it would be the best quality. I wouldnt take this for FREE- Sagging, lumpy, cant hardley sit on this let alone sleep on it. We paid a lot of $ for this set and if there was a way to return and get my money back I WOULD in a heartbeat. Lets see if anyone responds.
A special thank you to Todd Riecke and Patrick Wolf for going above and beyond to make things right for my husband and I. We purchased a bed from a local retailer and they ordered the wrong bed. The local retailer after many calls back and forth refused to do anything about it. I called the company and talked to Patrick Wolf and between him and Todd, we had the correct mattress delivered to us within a week and a half. We love the plush copper infused bed. I can't rate them high enough for quality and service.
This is such a great mattress. We found it at the local mattress firm and couldn't be more pleased.View More Reviews
The mattress felt excellent in the store, but once we slept on it for a month it started to cause back pain. I am hoping it is just an adjustment period, but afraid if it isn't.
This mattress was great in store. But after we got it home, it started to sag within weeks. After a few months, it is starting to affect my sleep because me and my husband are tossing and turning all night long. What a disappointment.
We got the Oasis Resort and within the first year it had completely deteriorated. Massive sagging issues and big lump in the middle. This is not what we wanted and now we are stuck with it because our warranty claim was denied.
We bought a $1400 Sherwood mattress and after 4 years, it was sagging so much I woke with a back ache. Went back to the store and they said they no longer carried this brand because customers were unhappy. Contacted Sherwood and their 20 year warranty was meaningless because they determined it was just fine. More money DOES NOT mean quality.
When we first got the Sherwood Oasis mattress in 2013 the first 2 yrs it was a good comfortable mattress we were happy with. After year 2 it began sagging in the center and by year 5 it had to be replaced
The seam of this mattress is coming undone after 3 years of normal use. Sherwood will not honor warranty because my kid spilled water on the mattress, which soaked through mattress pad and caused some yellowing of mattress. I think the yellowing is actually coming from INSIDE the mattress, and is brought out by the water. This is an obvious manufacture defect that the company refuses to fix due to a minor and UNRELATED stain. The 20-year warranty is bogus, and the quality of this mattress is lousy. Avoid.
I am a 81 year of age Male, sleeping alone on this model 7322 & mattress purchased 4 .5 yr ago & will be visiting mattress firm to see what compensation I will get , as mattress is in poor shape & hollowed out 6" deep from 170lbs, cannot spend rest of my days on this , it was great for 2 years, lacking durability as others have reported.
I bought this $4000 mattress and within 18 months it was junk... like a 300# person slept in the middle for ten years
My 13 year old complained about back problems. My husband and I noticed that the mattress sagged and the box spring was broken (very cheap pieces of wood) pieces of wood dangling under the box spring. Contacting anyone at Sherwood was a feat in itself. After getting a hold of someone (3 days later) we submitted pictures and a Inspector came out. Sherwood emailed that they are happy to replace, but I'll have to pay for shipping cost ($300 + $100 for removing old mattress). In the meantime, my son sleeps on the floor until this gets resolved. DON'T BUY SHERWOOD.
