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.
Helix is one of the most innovative companies in the mattress-in-a-box movement. Over the last 3 years, they have been offering fully customized mattresses to customers with their high-tech sleep quiz. Being one of the first to provide dual sided firmness options, they also have made it even simpler for customers to select the right mattress (even if they don't want to use the sleep quiz). With 6 comfort designs to choose from, Helix has really focused on delivering to every type of sleeper.
Based on our aggregated reviews and our scoring method, we recommend Helix in this match up!

Mattress supportiveness is an important factor for everyone -- especially stomach and back sleepers. Also, having good support that aligns the spine is a must-have for side sleepers. For most, these mattresses are above average in terms of support. Some, however, have reported issues with support so if you are heavier in body type, make sure that your selection is right for you.
This mattress does well for most in terms of providing edge support. But, some heavier customers may experience some dipping close to the edges.
If a brand invests in good materials, design, and quality control, durability should follow. Mattresses that sacrifice these attributes may have durability issues for some sleepers. Unfortunately, these mattresses get mixed reviews from customers on durability. Some folks report a cozy night's sleep, but others have had comfort issues over a shorter than average time frame. Make sure to do a last check on the 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
My helix isn't perfect but it's a whole lot better than what I was sleeping on before. After a couple months I've noticed a little sagging on the side I typically sleep but overall I love my mattress, sound investment.View More Reviews
The mattress is fine, it's pretty hard so we had to put another foam mattress on top. Also, I move alot when I sleep and my husband can still feel my movement. I am not sure this mattress was worth the price, but it's ok I guess. I probably wouldn't recommend it to anyone.
we just spent a week in another "custom" bed and was so happy to be back in our HELIX bed. These new beds are so dang hot, I hate it. BUT not our HELIX. Happy mamma to be back in her cool bed. Thank you.

I was completely unsure if I should try this new bed in a box thing. I took advantage of a sale and had it in a couple of days. I set it up in the morning, hoping any off-gassing would be done by bedtime, to my surprise, there was none. The bed was/is super comfortable, I'm glad I took the chance. My only complaint would be I had to figure out how to dispose of my old mattress. Highly recommend!!!
We are on our second full month of sleeping on this amazing mattress. No issues of being too hot. Very comfortable.
Oh my gosh, we LOVE our new Helix mattresses! We bought another brand about 10 years ago, and hated it after only a few months. This time, we did our research more carefully, and also made the decision to go with two XL twins pushed together, instead of a king. That way, I could get my mattress my way, and he could have his softer. We have slept better than we have in years! Plus no sagging in the middle ... easier to move ... no movement when one of us gets up in the night ... I only wish there were some kind of special headboard so we could slide them apart more easily when we change the sheets. I know I'm gushing, but I can't believe what a difference having a good mattress makes. Kind of fun to unpack, too. ;-)
Comfort galore, buy one and you will be sleeping on a cloud.
This bed is no joke. We actually had similar styles and got a blended bed. We have never slept better. A bed made for your weight, height, and position...how could it be better?
We purchased a Helix a few months ago and so far we love it it's comfortable and doesn't sleep hot. We also go the pillows that are cool to the touch which helps me fall asleep quicker
We ordered the soft and it was too stiff.
This mattress didn't end up being the one for us however I thought it was important to say how easy the experience was. I anticipated some push back when I started the return process. The Helix rep was very professional and the return process was easy and seamless. You can buy this mattress worry free. I would recommend anyone looking for a new mattress to give Helix a try.
First few days took some adjusting but after that I was fast asleep in minutes
This mattress is a dream come true. I can sleep on my back and sides without pain. Although it was a little stiff at first, Helix sent me a topper for it which changed everything. If you like the soft layer of a topper, choose a softer option when building your bed and you won't need the topper :-). If you are not convinced, try it. It's worth the 100 day trial!
Arrived damaged. lots of back and forth as to either send back or donate. The donation process is complicated and now the time is expired for that. Not the best experience and I now have a damaged product.
We have a vacation home by the sea, so lots of summer family visitors, everybody has uniformly loved it, we love the fact that it's square till the edge with none of the usual round off that make you feel like your falling out of bed when your near the edge.
Soft and comfy upper layer with supportive mid-layer. I've slept like a baby every night.
The Helix mattress arrived as promised. I was able to inbox it myself in a small room, but recommend 2 people. Comfort-wise, the mattress has been too soft. Th reason for this, I believe, is the only flaw in your order system. I was not allowed to adjust the results of my sleep quiz on your site. I almost did not order because of this. This mattress is better than the Nectar I tried, but the your software' results of my quiz are not necessarily accurate.
Great ordering experience. Shipped wuickly and arrived on time. The survey did a better job of matching to my preferences than my wifes. Great feel and support. Edge support is a little lacking, but otherwise i am happy with the results. Def feels better for back sleeping as it feels fully supported. Not quite as good for side sleeping for me but I have wide shoulders and have had a hard time finding a mattress that can do the trick.
Everything is going good. Sleep really well and it has good suppprt. I would probably go a little firmer next time around. The real test will be a year from now to know if it is building grooves.
Wish it was better. Price point is right. Advertised as firm but closer to soft medium. Nice that it was delivered. Not cool at all- despite how it was advertised. Not a stomach sleeper bed, only good night sleeps I get are on my back. You pay for what you get.
After sleeping an a multitude of different mattresses throughout my teens with moving houses and eventually starting college. I can safely say that this mattress has made my sleep an absolute pleasure. To really know that this mattress is for me in all aspects really adds to the value it gives me and for a cost that is much less than other very high end mattresses. Couldn't be happier and hopefully I won't need to change in the near future.
I ordered my mattress too firm but they got me a 2' topper and I sleep wonderfully.
My husband and I couldn't be happier with our purchase! It's hard to get out of bed in the morning because we are so comfortable!!
We are so enjoying our new mattress and foundation! No more aches in our hips and backs. Restful sleep has returned, thanks!
The mattress is too firm for me, not enough sink. It was supposed to be medium soft with lots of sink.
I was really excited to get the new Helix pillow with extra cooling. I sleep hot and I thought it would be awesome!!! Love the mattress so I had high hopes. The pillow itself is comfy, and it's neat to be able to add or remove filling so easily, but the extra cooling is non-existent. I even tried different pillowcases - a low thread count is what they recommended, also tried a bamboo one that was supposed to have extra air flow. Also tried no cover at all (but since you can't wash the pillow, I didn't really want to do that) but it didn't help. I'm still debating sending it back.
I tried the Casper for 90 days and I just couldn't get used to it. Way too firm for me. Replaced it with a Helix and I couldn't be happier! It is the most comfortable mattress I have ever slept on. I can now sleep on my side as comfortably as on my back. The only downside is that it is much harder to get out of bed in the morning.... seriously.
Once I got this bed I finally woke up with no pain what so ever. It definitely takes some getting use to but I highly recommend.
Since we purchased our helix mattress I've had the most restful sleep that I've had in years. We had purchased several other mattresses and with in a short time were very disappointed! Not with our helix! My wife no longer has back pain every morning and neither do I . We awake feeling rested and ready to start our day!
We have had our Helix blended mattress for 7 days. How refreshing to wake up without any back pain or aching muscles. The turnaround time from order to deliver was so fast! I'm so glad we ordered it.
I love the bed. Best sleep I have have in so many years. But when I ordered I originally looked at a king and wanted to order a cali king. But some how when I placed the order it was the original one that got pushed through so I got a king. Other than that mix up I am very happy with it.
Had pain with last bed switched to this one my back feels great now I have had it for 8 months and it's great
We needed to replace our 12-year-old mattress and decided to try the online experience. After some research, concluded that Helix was the right company. Totally liked the sleep survey to customize the mattress. Was really fun to unbox and watch it "come to life". The first night was awful. Then it got a little better but felt like sleeping on a board. So I decided that instead of throwing in the towel (because support is good for you), we'd explore other options. Went on Amazon and bought a down alternative feather bed topper for like $100. Made all the difference in the world. Now we have a good solid mattress AND a great pillow top.
Arrived quickly. Set up was a 5 minute process with most of that time getting the mattress out of the box. Fully relaxed into it's full loft by the end of the day. About two days with no sheets before I noticed the scent had disappeared. Was replacement for guest room but I've napped on it a few times and thought its was perfectly comfortable.
Before we got this mattress, I was waking up 10-15 times most nights, and we had a memory foam mattress (although it was used and we didn't know the age). I also had a lot of trouble with severe temperature changes at night, which would keep me up. With the helix mattress, except for a bathroom trip, I often will sleep through the night!!! I cannot believe it. Truly.
Pretty good. Hot at first but seems to have improved
We gave the bed nearly 100 days before deciding it was not the mattress for us. How dors one really know what configuration is right for them! The one thong we got right was the sleep cool feature. The bed seemed way to firm and yet seemed to cause hammocking. We tried several layering options on top of the bed with some success. Thank you Helix for always answering my questions, your customer support was much appreciated.
How to describe? Not like sleeping on a cloud, because clouds look lumpy. How can a mattress feel both firm and cushy? Don't know--but it is. My dog likes it, too.
I just got it out of the wrapping last week so I'm sure my body just needs some time to adjust or whatever. I've heard nothing but positive reviews.
