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.
I was hesitant to purchase Lull, due to the fact of not having access to trying it before buying. However, purchasing Lull was easily the best decision. I find myself sleeping much better each night. The bed is so comfortable! It took me about a week to get used to it. I highly recommend this mattress to you!View More Reviews
We have had our mattress for 2 weeks and me and my wife LOVE IT!!!!!
My wife is sensitive to outgassing from new foam products. A $1600 Serta mattress we purchased a year ago required multiple days of airing before it was "sleepable". However, this mattress (Twin XL) was out of the plastic cover and on the bed and sleepable the same night. The only think is that for a side sleeper, I would have preferred a bit more firmness. However, the mattress is very comfortable and the value is GREAT
Comfortable, easy to assemble and great customer service!
A much better sleeping experience and much better shopping experience too. One of the things I dread about mattress shopping in stores is that the choices are overwhelming and the added high pressure doesn’t help. We love our Lull. We haven’t been able to sleep a full night in the same bed for years. Now we prefer our full versus our queen which is an old mattress. Soon to be replaced I might add. With a Lull!
I have had my bed seen November it's great so far thank you
Best sleeping experience ever.
It took several weeks to see if we would Get all the benefits of the mattress. It Lives up to the high rating for sure Very happy
We had a rather crazy experience getting our bed, due to the shipping company. Lull was on top of it, and handled the situation well. They stepped in, and it was taken care of immediately. They checked it right after ordering as well. We couldn't be more pleased with the purchase.
I can see why they stand behind this mattress is a great product very comfortable lives up to its reputation
I absolutely love my lull!
My wife and I have been sleeping on our new Lull mattress for two weeks now and just love it!! We both used to have back pains and didn't sleep well on our old spring mattress. Back pains are gone and we both sleep through the night! Thanks Lull!!
I went into this with great skepticism. I admit it. I have always slept on a very firm mattress and I couldn’t imagine a mattress that shipped in a box would be firm enough. But after reading the reviews I figured I’d give it a try (the 100 night guarantee had a lot to do with that decision). And I’m so glad I took the leap. Crazy fast shipping! I gave it one night for it to plump up all the way and blissful sleep ever since. I’m honestly sleeping better than ever. I have plenty of support but the mattress seems to conform to every area of my body. Lull lives up to every promise.
I have been sleeping on this mattress for about a month now, nothing but raves from me. I would recommend a Lull Mattress to anyone considering buying a mattress and encourage anyone who has not given a thought to buying a new mattress to change gears. As a bonus, I paid for this mattress one day and delivered the next, can't beat that for service. Let's see: didn't have to go to the store, didn't have to deal with sales people, didn't have to find a way to get it home or pay a delivery fee, the utility of this mattress is incredible, hmmm, musta made a good choice. Best.
Checking in after a couple of months and still so thankful I decided on 'My Lull'. From the first night till now, I continue to fall asleep quickly and never have an uncomfortable position . I am a very happy side sleeper. I never felt the 'adjustment period' from a spring bed to this type of product. What I felt was comfort and simple and grateful full night's sleep. As others have said, my own sciatica disappeared. Proof to me about the alignment of your body makes a huge difference. I noticed it NOT being there after about the 2nd night. That's how quickly Lull showed me how much I needed this bed. I had sciatica for a few months, no idea why or how it started, but no longer a part of me. I also never had the odor from the mattress or packaging either, that some others had and also said left after a few days. I lucked out all around! If you feel you are all wrecked and also have an old spring bed, it's so worth buying this bed. Also the financing plan to make it easier for you if needed as it was for me.
mattress is really comfortable, and have nothing negative to say right now! getting a good nights sleep virtually every single night! love it!
Life’s good wife say s back has nt hurt since we started using lull
I broke my back a month ago and am in a lot of pain. Sleep has been very difficult. Got my new Lull Mattress and was so pleased. First night of comfort and peaceful sleep. The mattress sleeps cool and is just the right degree of firm/softness. The service and delivery was so prompt. Thank you ...THANK YOU ! !
I'll be honest that it took a few weeks to get used to... it's firm... but within that time period back pain went away, sleep got better, etc. - I didn't have to "get comfortable" after using the bathroom in the middle of the night, almost any position was fine. Worth it!
Love my mattress. Best sleep I’ve had in years. Firm, but not too firm. So glad I decided to go with a Lull mattress.
Everything was excellent. It arrived a lot sooner than expected. It was easy to set-up easy and unwrap. So far I love it.
I've only slept on it a couple of times because it's at my new house right now but every time I've slept on it, it's been amazing. I don't have anymore back or neck problems. It's very comfortable, I no longer experience tossing and turning. It's great.
Great, comfortable sleep, and awesome bed.
It is heavenly.
We have had great experiences with it so far. Definitely an upgrade from our old mattress, we love it.
Very convenient, process of getting into the house and on the bed was very simple and easy. Astounded by how easy it was to finance.
Really simple, fast, and easy. And so far we love it.
Amazing mattress. I am really happy with it!
It's fantastic! I purchased it for my mom, so she loves it.
Good experience it was exactly what i expected.
I can sleep on anything, my boyfriend is picky but he absolutely he loves it. I do sleep a little hot on it but other than that it's great.
Very very comfortable. My husband has had problems with his back but now he is getting six hours of sleep at night.
I purchased this for my son, he is very happy and has not complained. The minute we opened it he's loved it. He usually has back and neck pain but he's had no pain from this mattress.
I think the bed is working for us. My wife has a few issues with her back so we are still monitoring my wife's back pain and seeing if this bed is working. I think the mattress is helping us with better sleep.
It's great! Really comfortable. I am sleeping pretty well on it.
Website was good. It's for my daughter. She likes it a lot.
I really enjoy it, it's a great mattress. It's better than anything else I've tried. I love that it's the right amount of firmness. I love that it came in a box and was easy to set up.
It's getting better. In the beginning I needed to adjust, I was having some back pain, but still working it out.
