Helix is one of the most innovative companies in the mattress-in-a-box movement. As a leader during the industry disruption in the late 2010s, they started by offering customized mattresses based on their high-tech sleep quiz, being one of the first to provide tailored firmnesses based on body type. Over the years, they have made it even more transparent for customers to select the right mattress, with 6 comfort designs to choose from (and thicker, Luxe versions). Whether you want to select for yourself or use their sleep quiz, Helix really puts a focus on delivering for every type of sleeper.
Sleepy's Mattress is a wholly owned Mattress Firm brand and mattress in a box offering for very competitive prices. With mattress offerings in foam, innerspring, and encased coil designs, there is a wide range to choose from, both in-store and online. However, over the years there have been some disagreements about durability and perceived quality as well as sometimes lack of availability for certain models.

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.
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.
