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.
Tomorrow is liquidating as of May 2019 and may have no more inventory. Tomorrow is an innovative factory-direct sleep company offering a variety of sleep products like an impressive sleep tracker, adjustable base, pillows, sheets, comforters, and more. Their extremely comfortable hybrid and all-foam mattress is built with generations of expertise and data from Serta Simmons and has higher value materials at a lower price than many competitors in the market. With impeccable customer satisfaction scores, this brand is a market leader to love!
Based on our aggregated reviews and our scoring method, we recommend Diamond in this match up!

Bowling Ball & Density Tests
These mattresses do great at showing off their even support in tests. Although the surface layer will allow for a comfortable sleeping surface, the layers below provide lasting support for your shoulders, back, and hips.
Designing higher quality mattresses that last is a difficult issue for mattress brands. They would have to invest in better materials -- from coils and foam, and put their products through even harder testing. Also, it is something that can be affected by other factors -- like comfort, body weight, and overall use. That all being said, these mattresses actually perform exceedingly well for the long term. 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.
Had the mattress 40 days was nice but wife did not like it . I called to return 2 days later they were there to pick up . The return was easy like wowView More Reviews
I did a lot of research about hybrid mattresses and liked the concept but the in-store prices (even for year end and holiday sales) were pretty steep. Normally J would be leery of buying a mattress without having at least tried it out online, but I took the chance based on the great reviews and really feel I got a high quality mattress at an exceptional price. Getting it through my bedroom door and into my bed frame by myself once it had been unwrapped was interesting, lol- it was like trying to steer a 110 lbs Chalupa (got myself a queen medium firm), so you might want to enlist a friend's help. But I managed alone, so other than that whole experience was extremely low maintenance and I would highly recommend this mattress to anyone. Been sleeping great and having less aches and pains as a result, having a great mattress makes a bigger difference than you realize! Enjoy!
Ever since I bought my Tomorrow Sleep mattress I have never slept better. My lower back thanks me every single night. I highly recommend buying this product.
To be fair, I didn't think we needed a new mattress. I was fine, but my husband was miserable! His neck hurt, his back hurt, his legs ached...every morning. So, we researched lots of mattresses and decided on the medium firm Tomorrow Sleep mattress. Well, it's been over a month and we are so happy! No more aches and pains at all. For reference, he is 6'2" and 220 pounds. I think I am more comfortable too. I liked our old mattress because it was a pillow top and I liked the squishy-ness. This doesn't have that, obviously, but it's still soft and yet really supportive. There doesn't seem to be the issue with heat retention like traditional memory foam. I also appreciate the fact that the edges of the bed don't sink like other memory foam mattresses. Overall, we would definitely recommend this mattress!
Originally got the firm, but changed to the soft and am very happy with it. It cradles my body with plenty firmness and stability.
The mattress came and was easy to install. I did it by myself up a 3rd floor of a Manhattan walk up. The mattress itself is amazingly comfortable. The memory foam doesn't make you feel stuck or sunk but provides just the right level of support. I'm super happy!
I wanted a mattress that would work with an adjustable base, but was concerned about 'sleeping hot' on a memory foam mattress.
The Tomorrow mattress is a great alternative for anyone who wants the support and comfort of memory foam with the 'breathability' of an inner spring. I sleep deeply and comfortably - not too hot...not too cold...just right!
This mattress is the most comfortable mattress I have ever owned, it was also very well priced. I would definitely recommend this company to friends & family. Very pleased customer.
We purchased the Medium Firm and love it, although I'm sure Medium Soft is equally as epic. For the first time in years I am sleeping through the night and not flipping around trying to find the least painful position. I just can't recommend this mattress enough!
I've had this bed about three weeks now. I got the firm one. It sleeps comfortably, though I think I would probably prefer the softer one as I am a side sleeper and this makes the bottom of my ribs a little painful some nights. Also, the two bottom corners never decompressed fully so the bed isn't necessarily a box in shape as it is more rounded on the foot of the bed. This isn't as obvious on my bed frame with a duvet on it.
I ordered the firmer mattress as I needed more back support. After 2 nights I found it to be too firm,both for my wife and I. I called customer service and they sent a mattress topper. It didn't help. I called customer service and asked for the bed to be picked up. They were extremely helpful and arraigned for the pick up and full refund. Very pleased.
I thought I was sleeping fine in my last bed, but my Tomorrow Sleep mattress is comfier than I ever thought possible! The medium firm offers great support and the perfect amount of sink in the memory foam. At the end of the day I look forward to the joyful experience of climbing into bed.
My wife and I had a bed from when we got married 10 years ago. It was horrible and we knew it but couldn't afford anything until now. This mattress has changed everything about sleeping. We now look forward to going to bed, spend time reading books in the bed and struggle to get out of bed in the morning! With our old bed, we looked forward to hotels for the beds and now? We have a great bed at home!
We switched from a very high end but old matress. I am a 100% side sleeper and I have found that this bed is very comfortable for me. I see less back pain. My wife (a stomach sleeper) is still on the fence. She feels that it get's more comfortable every night but I think the adjustment period for her will be longer. We purchased the white glove service and that was flawless. They came and took our old matress and had the new one up in minutes. No real noticeable off-gassing or orders. Overall pleased so far but plan to evaluate over the 100 day sleep period.
We went with the medium-soft mattress. My girlfriend is uncomfortable sleeping on firm mattresses for more than a week or so at a time. I've had a Keetsa for a while which was nice, but it got lumpy really fast and it's firm so we needed a change. We cross shopped a number of mail order mattresses and knew we absolutely didn't want all-foam. The tomorrow sleep medium-soft is supportive and comfortable while still being cloud-like and soft, a perfect combination. We're really happy with it!
The shipping container was sturdy and the included tool to open the plastic safely is a really nice touch.
I ordered the mattress on Tuesday and received it on Thursday. Super fast delivery. Quick and easy set up. But, the best part was the sleep. I have the medium firm. I had such bad back pain from my old mattress that disappeared overnight. I am thrilled with this purchase.
We loved both the ease of delivery of this item and the product itself! The mattress arrived fast and was easy to get out of the packaging & set-up! Note the medium-firm is definitely on the firm side, which is what we we were looking for. Also, be patient for the sides of the mattress to plump up after laying flat. We ordered the mattress a few months ago, and have been sleeping well ever since.
I've been hesitant to buy a "bed in a box" solution for a while now. I'm surprised at how firm the mattress is at first but when you lay onto it it conforms to you in a great way.
This is one of the best decisions I have made in a while. I was in need of a new mattress because my old mattress was about 12 years old. Given that I have two surgically repaired shoulders due to epilepsy testing (I have epilepsy) sleep is a crucial part of my regular routine. I need 7-8 hours every night and the mattress has been a huge help. I was so impressed that I decided to get one for my dad's Christmas gift. He is in dire need of good quality sleep as well.
We purchased this mattress 3 months ago - in the height of summer in Florida. Our old mattress always slept "hot" - blankets tossed on & off nightly. This solved that problem. Used prior bed's old foundation. I also purchased an "outlast" lightly quilted blanket (Sealy) , and the Tomorrow mattress protector for a totally temperature-regulated sleep environment. Oh, and it's very supportive for various sleep positions to boot. Purchased the medium firm. He loves it very firm. I still find it quite firm when laying down at first, but then it gets more comfy and you start to kinda sink-in. Happy Purchasers' are we!
I love the comfort and stability of the mattress. I sleep soundly and wake up with no back pain at all. Customer service and delivery were excellent. But it feels smaller (narrower and shorter) than my old queen mattresses and doesn't perfectly fit my standard queen bed frame.
I did a LOT of research before purchasing this mattress. I watched YouTube videos with reviews on boxed mattresses and read several blogs. At the very end of my research I saw a video talking about this mattress and how overwhelmed the reviewers were by this new mattress. So I decided to take a leap, specifically for the hybrid aspect. I liked the idea of the individually wrapped coils combined with the memory foam top. My husband really needed something softer, that relieved the pressure on his nerves, while still supporting his back. He works long hard hours on the powerlines, sometimes working 28hr work days. I'm happy to report that after having this mattress for a few weeks now he can positively say this is the most comfortable mattress he's ever slept on. He is constantly calling this mattress "magical". For the first time in a long time he says he wakes up actually feeling refreshed. He used to wake up with numb hands and lots of pain in his lower back. Now he says his hands no longer go numb by the morning and he wakes up feeling no back pain at all, even after working incredibly ling hours. This mattress is awesome. Literally one of the best purchases we've ever made. I know for a fact we'll be buying more of these mattresses in the future as we phase out the others in other rooms.
Naturally, I'm pretty stubborn. Especially when it comes to choosing a new bed over one I've been used to for most of my life..
I have two herniated discs in my lower back and I've been having a lot of trouble finding a matress that would allow me to have a well rested night's sleep.
After doing plenty of research, I came across Tomorrow Sleep as having one of the better mattresses to help with those, like me, suffering from back pain.
I must say, I have been pleasantly surprised at how comfortable this matress is. Not to mention, it costs much cheaper than many of the traditional beds I had been shopping around for.
Overall I rate this bed pretty great and so far I've been pretty satisfied with the results.
Been having trouble sleeping due to my back. I didn't know if my current mattress was too firm or too soft. I finally jumped on a leap a faith and tried tomorrow sleeps firm mattress. I've had it for a week but everyday so far my back has been better. I still get neck paid but I believe that's becaue my pillow is too stiff.
I am very particular about mattresses and have normally spent thousands. I spent way less with Tomorrow sleep and couldn't be happier!
I have struggled sleeping due to tremendous hip pain. I went from a firm mattress to a memory foam mattress that I've had for the last 4 years. Nothing worked. I read about this mattress, saw it was reasonably priced and stayed within my budget so gave it a try. NO PAIN! No pressure points of pain! none... I don't know how it does it as it doesn't feel that soft. I read the reviews about the medium firmness feeling to firm so I got the soft. This is a Firm mattress with a little bit of give. I expected it to be a little softer, give you that sink in feeling. however I was so pleasantly surprised sleeping on it that it was so perfect... It felt "luxurious" and like I said no pain.. so not sure how, but it works....
This is one of the best mattresses i've ever slept on. Fist night, laying down i was out like a light. The best!
I highly underestimated the impact that a high quality bed could have on my life. Even through the moment of purchasing a Tomorrow, I had my doubts. Two weeks later, I am a believer. I wake up rested... Fully rested. My nights are better, and my days are better. Thank you, Tomorrow.
My wife and I purchased a Simmons Black Hybrid mattress and really love the mattress. Our teenage son's mattress was getting old but we didn't want to spend the "Simmons Black" kind of money for him. We found Tomorrow's Hybrid mattress with a google search and the positive reviews and much less expensive pricing convinced us to make the plunge. Our son loved his mattress and commented that his back doesn't hurt anymore when he wakes up. We also decided to buy one for our guest room and our daughter slept in it for a week when she came home from college and mentioned it was the most comfortable bed she has ever slept on. When I lay down on the mattress it feels awfully close to our Simmons mattress so much that we may go the Tomorrrow route when we replace our mattress in the future.
I feel like Daddy Warbucks in the closing scene of Annie. If only my desk chair at work felt this good, I think I would be a millionaire by now. But seriously, I love this bed.
As a side sleeper, I thought waking up with hip pain was a way of life. After 3 nights on the Tomorrow Sleep hybrid I have woken up pain free each morning. I'm saying goodbye to innerspring mattresses forever!
After laying on the mattress after it had come straight from the box, I was a little worried. It felt like I was laying on cardboard. Hah.
But! After coming back the next day (new mattress for the new house), i was very happy with my decision. I really like it. Hopefully the GF does too. We were going to go with a stearns and foster. I had actually already ordered it after trying it out in the store. But! I compared the materials and how the mattress was made, to this Tomorrow Mattress and decided to take a chance.
The price and the anatomy of this mattress is what made me select this. I've only slept on this mattress a handful of times, but, so far so good.
There's a confusing list of choices today with so much competition in the mattress world, I'm very happy I chose Tomorrow Sleep. I honestly haven't slept better in years. Where was this mattress 10 years ago when I paid $2200 for my old one? There's no comparison.
For years, I used to wake up practically hunched over with back pain. It was a struggle getting through my morning and I thought that this was just a facet of aging. Then, I started sleeping on the Medium Firm hybrid mattress from Tomorrow. To say that it's changed my life is an understatement. I wake up now with no backache; instead I've got a spring in my step!
This mattress is so well constructed. I travel a lot and I find it better than the best hotel beds. I can already tell after a few months that it's going to stand the test of time. Best quality at a very affordable price. I highly recommend it.
I don't know how they did it, but Tomorrow Sleep has made a bed that stays cool all night. I've grown used to waking up in the middle of the night hot and uncomfortable, tossing around trying to find a cool spot. I tried sleeping without a blanket, keeping the window open, and even using the AC in the dead of winter. Who knew all I had to do was change my mattress? I'm finally able to sleep through the night and not be a sweaty mess in the morning.
This bed is definitely better than I expected! I often sleep right up to the edge of the bed and with my old mattress, I've actually fallen off of it a few times.... embarrassing and painful, I know lol. Not with my new Tomorrow Sleep mattress! When they said this bed has edge support, they meant it! I can also tell that they put a lot of work into the full construction of the bed. I have 2 toddlers who think my bed is also their bed, and so far, this bed has lived up to the demands of a busy family life. I decided on the Medium Firm and it is fantastic!
This mattress helps keep us cool and comfortable when sleeping, unlike our previous bed, which was all-foam and super hot! Now my wife and I fall asleep with no trouble... our dog Pete seems to really enjoy it too!
I use to wake up with really terrible backaches from my old spring mattress. However, once I started sleeping on my new Tomorrow Sleep bed, I have been waking up with much less pain and soreness in my lower back. I got the Medium Firm and I think it's giving me the perfect amount of support... best decision I ever made!
My husband and I both have lower back pain, and the medium firm mattress offers great support. We also love the fact that we aren't disturbed when one person gets up in the middle of the night. The set-up was so easy too!
We will definitely recommend this mattress to our friends and family!
