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.

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
My husband and I love our new mattress. We are sleeping better than ever.View More Reviews
Purchased this bed a couple weeks ago and wanted to give it some time to make sure before I wrote a review. This Bed is Fantastic! I did so so so much research and reading of reviews on beds to make sure I picked the right one. I'm still trying to figure out what some of the two star reviews are talking about. I'm almost mad they made me so nervous about purchasing the bed. I purchased the King in medium firmness and it is so comfortable....to the point that I was late for work one day which never happens! Keep in mind, my last bed was an old spring one with a memory foam topper. I think what really sold me was the customer service. The people that I talked to on the live chat were super awesome. I spent 10 minutes talking to one guy about my body weight and trying to decide which level firmness I should go with. Another company I was leaning toward was more expensive and didn't have any Black Friday deals. This wasn't a problem but the way they told me was. They went on about how they are a true mattress company unlike these "phony" other ones and that's why they don't give deals.... and you had to pay 100 bucks for delivery. anyway the customer service was fantastic and in my opinion that wins out every time, especially when it comes to returning something. In conclusion, mattress is great, I'm hoping to be able to get their pillows some day.
I wrote a review before for the Alexander signature bed, but it did not get posted. It was either too long or nest bedding didn't like what I said. I ordered the bed in the king size and medium firmness. At first the medium felt very hard and I had to check the tag on the bed to confirm it was medium. After a few weeks the bed softens up very nicely. Overall the alexander signature is extremely supportive and provided great pressure relief. the main issue my wife and I had was the bed slept very hot. We purchased a foundation from nest that was breathable (we were using new tempurpedic flat foundations). We also purchased bamboo sheets, wool comforter and linen duvet cover and four different bed protectors (two waterproof and cooling and two non-waterproof and cotton). Using the organic cotton bed protector the bed was cool enough to sleep on on most days. Ultimately we returned the bed for the hybrid latex. The bed would be a 5 star product if it slept cooler.
I returned my signature hybrid bed for the signature series "medium" because the hybrid did not feel enough like memory foam for me. The new mattress feels much more like a memory foam bed but maybe not quite to the level I was hoping. The mattress does sleep bit warm but overall comfortable. Customer service has been great.
Great bed and really helps with my back problems
I purchased the signature series medium firmness in the king size. I had very high hopes for this bed. I purchased a $2k bed from Denver Mattress about 1.5 yrs ago and have suffered from back pain the entire time. The Alexander arrived from FedEX (dumped in my driveway. Not nest bedding fault, but a lazy fedex driver). When I opened the box there was minimal offgasing, which went away quickly. I originally put the Alexander on a solid tempurpedic foundation. The bed at first felt much firmer then a medium. So much so that my wife wanted me to send the bed back after one day. After about a week the bed softened up very nicely and is a true medium. After the bed broke in a bit it was with out a doubt the most comfortable bed I've every slept in. The only problem was, my wife and I were waking up every night extremely hot. We were both so hot that it was hard to sleep. We tried two different cooling waterproof bed protectors, and a regular pillow-top non-waterproof cotton protector and bamboo sheets. The cooling protectors made the bed sleep hotter. I then purchased an organic stretch knit cotton protector (non-waterproof), the nestbedding foundation (which is very breathable) and the bed did sleep cooler (although I spent hundreds of dollars at this point). By this time I had already ordered the latex hybrid bed from nest to replace the signature bed. Ultimately, I highly recommend the Alexander signature bed to anyone looking for amazing support and an amazing feeling bed. However, if you sleep very hot you might want to look at the hybrid or latex beds. Also, nest beding was very easy to work with on the replacement. They had me donate the Alexander signature bed. I was able to find a very deserving couple that was sleeping on a 30 yr old mattress that are beyond happy they received this bed. Customer service was excellent from Nestbedding. If the bed slept cooler it would be a 5 star review.
The best mattress I've ever purchased!!!
Really liking this mattress, it's been great to sleep on. So much support and nice and thick. It definitely still smells like memory foam though even after having it for more than a month. I let it air out for a couple of days before using and can still smell it. This varies from mattress to mattress I'm sure but just be aware it can happen.
Happy but at the moment having trouble with my shoulders hurting maybe needs to be softer. Contemplating ordering a king size if I can correct the shoulder ache
Bought this mattress because our $3500 Tempurpedic became senile and lost its memory after only eight years. This Alexander Signature series mattress has been great right out of the box. We have been sleeping on it now for about 6 weeks and NO complaints. We highly recommend this mattress & company. Fast , friendly, knowledgeable service.
Ordered online, wasn't sure I'd like it, but everything turned out great. Super soft and comfortable... my mom likes it better than her bed.
We have recently purchased the Alexander Signature series bed, and holy cow, I noticed a difference in sleep within the first week. I felt more rested, and it was sure comfy. It was really easy to take out of a box and move from the apartment building mail office to our apartment. The box ripped while we were carrying it, but it almost made it easier to grip the round mattress than the handles on the box. I would definitely recommend this mattress and nest bedding to whoever is talking about buying a new mattress. We also were able to try it out at an online mattress showroom we have in the Twin Cities called Sleep Sherpa. So if you are not from Minnesota, look up to see if there are any of those type stores by you!
Shipped quickly and neatly. Love the mattress, it needs a little time to mold into a custom fit the sleeper, and now after the adjustment period, I am finding more peaceful and restful sleeps. Love the financing tool as well! Super quick and easy.
This was our 2nd purchase from Nest for our guest bedroom. We love the Alexander soft and the service Nest also provides. Thank you!
Excellent. Well built/designed and no damage/flaws. I really am happy with this purchase, sleeping has improved and this is extremely comfortable. Sleepopolis was a fantastic resource for study. I chose this over five others. Very difficult decision, but again, I have no regrets.
Excellent customer service throughout the order process and all arrived as expected and on time. Bed is super comfy!
I’ll start by saying that I prefer a spring matress over memory foam but for a foam matress this is far and away my favorite I have slept on. Tried another brand and returned it as it was too firm for my preferences.
So soft. A guy my size, 230 5'9'' sink right in. Great on wife's shoulders as a side sleeper. I myself prefer a bit more firm but highly recommend this mattress and Nest bedding for that matter. Great customer service and great communication.
Love it. A great nights sleep.
We have had the signature medium for about a month, king size. When we first got it, it was really firm, I couldn’t even sleep on it. But, it has softened up a bit, but no much. I have to say that I have since gotten used to it, and I actually find it very comfortable. I am used to sleeping on a pillow top soft mattress, so the transition was difficult, but worth it in the end. I sleep more soundly, and my arms don’t fall asleep anymore. I am a side sleeper, and no more back and hip pain. I do however, wish it was just slightly softer. If you are looking for a softer matress and are stuck between the soft and medium, the medium to me is slightly on the firmer side. I am 5’7”, about 140 lbs. my husband is around 200, but he can sleep on anything. Overall great mattress.
I was hesitant to try buying a mattress online. I'm glad I did and I wish I hadn't waited so long. This mattress is not as soft as our last one but after sleeping on it a few nights, I realized that it is more supportive but still soft enough to snuggle into. Our previous mattress (from a retail store) in retrospect was too soft, didn't give enough support and was twice as expensive. This is a much better buy. My husband and I both love the new mattress. I'm glad I didn't go with the medium, it wouldn't have been plush enough for me. This feels more like a medium soft mattress. It was easy to set up. It's been over a month now and so far so great!
I own a king Tempur-Pedic Contor firm, spent $USD 3300 several years ago and my wife and I really love it. The Nest Alexander firm king we purchased two months ago is absolutely fully comparable to it in terms of comfort and full body support at one third the price. Excellent value for the money, we cannot distingush any differences between the two mattresses.
We had a spring mattress prior, never had memory foam. When needed, and overdue for, a new mattress, spent much time looking at mattresses and reading reviews. We got our mattress from Nest almost 4 wks ago. I like a softer mattress then my husband so compromised with a medium of the alexander signature mattress. Husband noticed a little outgassing, but I didn't (i do use 2 pillows). I did not feel there was any breaking in time, mattress was comfortable right away. Both of us are comfortable with this mattress although not sure it helps with my husbands back pain. I have a problem with hot feet so i was interested in the cooling of the mattress. The bed warms up under your body torso but elsewhere is cool. That helps me because i can move my feet and it is cool anywhere they are. There is some collapse at bed edge but has not been a problem and I do sit on edge to put socks and shoes on. It is difficult making bed, may be because set in platform bed and diff to get sheets around corners and edge- too heavy to lift corners up.
Was skeptical, but now a believer. Great night sleep.
Very comfortable mattress, but their customer service is what makes this company stand out. Excellent.
I purchased the Alexandar signature series and I couldn't be happier with my purchase! One month in and it's as comfortable as ever! It's hard to want to get up in the morning...
I cannot find the words to express our satisfaction with The Alexander Signature Series Mattress. It is the best mattress we’ve ever owned. Period. Back problems gone. Pressure point pains gone. Stiff joins in the morning gone. A perfect night’s sleep every night since it arrived. We could not be more pleased!
I'm in the process of contancting the company to try to change my mattress for the medium firm because the signature firm is almost like sleeping on the ground imo. I've had it for a month and a half and I've tried jumping on it and tried to break it in but it feels really hard. I'd go for the medium at least. 3 stars for positive customer support up to this point and the ability to finance through affirm
My review is not about the mattress itself since I only had it for a day but about the way it's been delivered. I received a notification that my mattress will be delivered yesterday. I took the old mattress down and started waiting at home. It was getting late and I was wondering why it has not been delivered yet. I opened the door to check and found the box lying around by my rose bushes far from my door and one side of the was box open as if it has been thrown. They did not even knock on the door, apparently just throw it and left. Believe me, I get lots of deliveries and I've never seen anything like this. So frustrating. It made me question whether I bought my mattress from a wrong company.
I am writing this review from my nest bedding mattress right now. My significant other and I are overjoyed with our decision.
This is our first memory foam mattress, to date happy with the quality. The mattress is firmer than I’m used to, but have been resting well. Maybe as it gets used it may loose some firmness but I would be okay with that. The delivery and set up went as planned no complaints.
Night #1 on our new Nest bed.... Well, we've tried 3 beds so far and we may have a winner!!! Thank you Josh in the Denver Nest Store who helped me with deciding on a model. Joe Alexander- after 1 night on our Alexander Signature Soft King - my husband got up and said his back felt good and the bed was "pretty good". That is a high compliment after 3 months of rock hard "soft" beds. And after 2 failed mattresses. A suggestion: R & D should come out with a mattress for waterbed lovers. We had ours about 20-25 years and it wore out. I know I'm not the only person who loved their waterbed and is now looking for that cushiony feel but is struggling. I hope we found our new bed!!! Looking forward to night #2!!! Kim 😊👍🏼🙌🏼
I sincerely regret purchasing this mattress, because pretty much all I think about when I'm at work is getting back into bed. I recently decided that it was time for a new mattress and after inadequate research settled on a Purple. I know several people who claim, verbatim, that they are "obsessed" with their Purple, but it was entirely too firm for my liking. I realized that as a side sleeper I much prefer a softer mattress. When the recycling company came to pick the Purple up when I returned it, they told me a lot of people return them. I purchased the Nest Alexander Signature Series in soft, and I AM obsessed. It's squishy without compromising support, you sink into it but not so much that you get stuck. I do still think it has a memory foam feel to it even with the quilting, but it's not as pronounced or slow to react as many memory foams. If you're a side sleeper who loves feeling like you're sleeping on a cloud, I highly recommend the Nest Alexander Signature Series mattress in the soft comfort level.
I love this bed! It's the best bed I have ever owned. The only bed I have ever slept on that felt better was in a fancy hotel and even though I looked under the sheets and googled the bed, it was not available for retail. I slept on my friend's bed that is the same as this, and bought mine based on that. I'm so glad I did!
I just got my Alexander Signature Soft Mattress and I LOVE IT!!! I've never had such an amazing mattress. When I lay on the mattress, it hugs me in all the right places and gives me support where I need it. I feel like they actually made me a custom nest for my body! I had the Purple Mattress before, and after Nest Bedding, I realize how uncomfortable the Purple Mattress was. Purple sells you a slab of rubber with holes in it and markets it as a bed. Nest sells you the Rolls Royce of mattresses with the finest materials at an affordable price. Don't fall for Purple's creative marketing. if you're looking to buy a bed, buy a real bed from Nest. If you're looking to buy a science experiment, buy a mattress from Purple. Even better, Nest customer service is AMAZING. I called in and spoke to Amber because I had some concerns with being a little warm at night, probably because of the mattress protector I was using (which I purchased from Purple) and she sent me the Nest Cooling Mattress Protector (which I'm very excited to try) FOR FREE!! You can't beat a company that cares about the products they make, and the customers that buy it. Beds are different for everybody, some people like Purple but I definitely prefer Nest Bedding. If you're looking for a Mattress give Nest a try, you'll fall in love! (and deep soothing slumber) Thank you Amber for making my sleep experience awesome! Very excited to try the cooling mattress protector!
Bought the Medium mattress but it was too soft. Sent an email to the company to ask about upgrading to the firm mattress as we were within thne100 day time frame. Received a reply from the president of Nest almost immediately confirming that the new mattress would be shipped as soon as it was manufactured. It is perfect and Nest has a lifetime customer
I had tried a Casper mattress and found it too hard, as I am a side sleeper. The purchase and shipping with Nest was easy. For the first night, I found the Alexander soft mattress to be too soft, but it took about two weeks for either the foam to firm up, or for my body to get used to it. I am now really liking the softness of the mattress, as it is plush on top and more gradiented below, while some other mattresses have a top plush layer, but you only sink until you hit a harder layer below. There was no odor with this mattress, the quilting on top is lovely and is nice enough without a mattress pad, and my dog absolutely adores the bed.
I tried 3 different beds to help my side sleep aches and pains and the nest alexander signature was the best for me. Company were great to work with.
We've never slept on memory foam before, so this purchase was a huge decision for us. We were coming from a 13 year old Sleep Number that couldn't be salvaged any longer. It took some getting used to for the first month, but I'm so glad we switched. No more morning back pain! Still adjusting to how it feels as a side sleeper and still healing from the joint pain the other mattress caused, but every day is better. Thank you Nest!!! I hope to buy another for our guest room one day.
