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.
Sleepy's Mattress is a wholly owned Mattress Firm brand and mattress in a box offering for a very competitive price. Their offerings include foam, innerspring, and encased coil. With multiple firmness options, they have something for everyone, and even have both an online shopping option. That said, there are some complaints about durability and craftsmanship.

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.
Purchased Sleepys king size over a month ago. I have never had a more consistent quality sleep. I work a lot and have soreness in my back and legs (not injury pains) and used to only sleep around 5 1/2 - 6 hours a night. I sleep soundly now with the Sleepys mattress. I would recommend this to any and everyone that's looking for a new mattress. First time I've slept past 9am in many years.View More Reviews
I bought this mattress 3 weeks ago and I have Fibromyalgia, arthritis, severe back pain, chronic pain for the last 18 years. Every mattress I had before caused some sort of pain, even with memory foam mattress toppers. I decided to try the Sleepy's Essential 8" Memory foam mattress and I'm so happy I did, I'm SO pleased with this mattress!!! it doesnt make you feel hot and it doesnt sag when you lay down on it; is a firm feel but its very comfortable. The first night I slept on this mattress I slept through the night and that is something I could never so before. My sleep is so much better since I purchased this mattress and I recommend this to any one who suffers from back pain or similar problems that I have. It was worth every cent I paid for it! Thank you so much Mattress Firm!
I purchased this mattress and have been satisfied ever since. I love the feeling of sleeping on a firm mattress with a little cushion so this was perfect. I liked sleeping on the floor as a child because of the firmness, now I have comfort and firmness.
I was surprised when they delivered it how it was compressed , After 2 hours of expanding it was ready to try in the comfort of our own home . It sits a lot lower than on the old matters ( felt like you would fall off a mountain with that one ) So far a delight to sleep on an we picked it out ourselves .
Sleeping so much better. Happy to have a great mattress.
I slept on this for about 2 wk and a half. First 2 wk smelled, so I tried to air it out the first couple of days by taking off the cover/ wash/ keep upright w/ windows open, ventilate etc. After 2wk the smell is alright. I like mine firm, so this one is okay. I prefer slightly more firm but overall this one is alright.
Bought it for my son, he is very happy with it and sleeps well at night.
The price quality and service can't be beat great job Mattress Firm
I brought this for my I Uncle who has mobility issues. After he got use to it, he was able to get in and out without any problem.
I received my bed on Jan. 25th, 2018 and it's just absolutely great.
Is firm firm firm I love it!!! Just like I expected thank you so much
My first night on this amazing mattress. I love my bed.
Bed is soft but does not return to it's original position well. I've been sleeping on one side and after about a week or two there is a noticeable difference in height between the side I sleep on and the other one.
I sleep so well on this mattress and that’s what count. Love this, love love love!
My wife and I live the new mattress and the price was right...thank you
I’m very happy with my new Bed! The pillow top is great balance between plush and firm mattress!!
Just got our bed today and i love it my wife and i both have bad backs and its perfect
This is the best mattress, hands down!! I did a lot of research and took a lot of different quizzes to figure out what kind of mattress works best for me, and this one came out on top. I have back problems and since I got this mattress last week, I haven't been any! It is plush yet firm and oh so comfortable. I also bought a mattress pad that has made sleeping so good. I 100% recommend this mattress to anyone and everyone!
I bought this mattress on 5/14/18 for $249.00 and I hate it! It is as stiff as a board and makes so much noise that even when the dog moves, It rests on a very expensive box spring that has never creaked before. I cannot exchange it without incurring another $100.00 fee. I have a back and neck ache that I did not have before sleeping on this horrible product.
My dad bought this mattress for my younger brother. He is very tall and is very active, he loves it! It's so supportive, not too firm or too soft, and very comfortable! I am surprised at how great the quality is for the price.
This is the first time i have bought this kind a Mattress, I had my doubts since my youngest daughter have one like this, i have two back surgery’s my doctor recommended me a firm mattress and said this is garbage mattress i said let me try it. I can’t be more happy! I got ut with the adjustable base, the best purchase ever. 5 days and 25more to go for. Since it takes 30days for your body to get used to a new bed.
The store clerk said we would not regret it if we went with our first choice on a firmer option. The queen arrived in a skinny rectangular box that we thought was the frame because it was so compact. Amazingly, over the next hour, it transformed from a pancake into a thick and luxurious mattress. We got the protective casing which makes me feel 10x better during everyday use that we will never have a problem with our warranty. So far, the bed is exactly what I wanted. When I go to sleep, I have a tremendous amount of support with enough give to make an indent where my body naturally curves. I'm about 125lb, and my husband is about 225. He says his indents do not as quickly rise when he changes positions, so it takes a minute until his side of the bed fills back in. It's only been a month, but I have confidence we are going to love and keep this bed for many years. I highly recommend the base with the header and footer rise. We always sleep with it flat, but the few minutes in an elevated foot/head position really relieve back tension. Thanks for a high quality product!! The bed is also beautifully stitched. I would come back. The deals at mattress firm are competitive for the quality you receive.
I am sleeping so much better, it is cooler I am not turning as much , I find my self wanting to get in bed n useing the feet n head posture in stead of siting up in frount of the T v in family room get to to work on my I pad ,
We slept on this bed for over two months and it just did not soften up as much as we had hoped, really barely at all. It is a very firm mattress but is still comfortable to sleep on though it just causes back pain for me and my partner. The cooling is great but make sure you have breathable sheets or it will be just as hot as any other bed. If you are looking for a firm memory foam this is great, just dont expect it to get much softer than what you get the first day.
bought this weeks ago and now my son is getting a good nights sleep
I have had this mattress for a few weeks ago and I am glad I went with the Sleepy's cool. It is a bit on the firmer side but this is what I like. For the price you can not go wrong. They had a special and I got a free adjustable frame with my purchase and I could not be more pleased.
I’ve been sleeping on the twin version of this mattress exclusively since it was delivered on 4/23/18. Some background: I had been experiencing a lot of morning mid-back and rib pain on my old mattress, and was not sleeping well. I am a mid-50s insomniac woman. I tried several models in the store, including Tulo and Serta iComfort memory foam, and chose this one due to its thickness, beefy feel and comfort during the 15 minutes or so of testing. Although it felt firmer than my preference, I figured it would be a good option for my back pain, and I decided to give it a try. I did not think to purchase a new foundation (“box spring”) at the time.
I just purchased in store 3 days ago and I love the cool mattress temperature and the fact of it having no springs. It's plush firm like cuddles your body I have a knee injury and in the last 3 days of sleeping on this my knee has felt better.also I don't need a bunch of pillows anymore my back feels great .. I will never go back to springs. This is a great mattress Try it...
I bought this mattress a week ago. I have had Simmons and Serra inter-spring beds up until now. We tried it in the showroom and were hesitant as it was very firm but since it sort of confirmed to our body and the price was right we thought we would give it a try. I can say now that it is taking us a bit to get used to this type of bed but are overall very happy with it and are confident that over time it will soften up a bit. It is a well constructed bd and we are happy with our purchase
I am so pleased with this mattress the best thing I like about it is that it is so solid that you can't feel the next person moving on the bed when they toss and turn or get up or lay down it's very comfortable and just what I needed
I bought this a couple months ago and love it! I sleep through the night!
Have slept in this mattress for 5 nights and was hoping I would get used to the firmness but unfortunately neither my husband or I sleep well in it. My children had a foam mattress and love it so we thought we would give it a try in our new beach condo. They obviously purchased something softer because this is extremely firm. Wake up each morning with a back ache. Going to call about exchanging it.
We exchanged a tulo for this mattress and were very satisfied. My wife sleeps better that she has for years. thank you.
I'm very happy with my purchase, the service and everything was great! I wouldn't trade my mattress for anything, and at unbelievable, affordable price, highly recommend them!
I love my new mattress couldnt be happier only if i could stay in bed longer
We bought our mattress a month ago and it was our best purchase ever. Can't wait to climb in bed every night. No aches or pains ever since our mattress was delivered. We give it a 5 star rating.
I had this mattress for about a month and although I love the feel of the mattress it seems hotter than a normalization
Value was important to us and this mattress was a great purchase.
You wouldn't think it but my old mattress was killing me! After one night of sleep on this mattress my left shoulder and back had no pain. Which hasn't been the case for almost a year. I thought I was just getting old turns out is was my bed! Sleepy's cool mattress me and my wife thank you its been over a month and we can't say enough to thank you for such a great Mattress and for relieving what felt like years of pain. I do have one question for you do you make pillows?
Too early to tell ... so far I like it. No recommendations yet.
