I received a free Cocoon mattress for review from Tempur Sealy. The Cocoon mattress is a mattress in a box made by Sealy. Sealy has been in the mattress industry since 1881 when the founder, from Sealy Texas began compressing cotton for use in mattresses. The company is now known at Tempur Sealy as the Tempurpedic purchased Sealy in 2012 making them the largest manufacturer of mattresses in the world.

The Cocoon mattress has been featured on Oprah’s Favorite Things list for 2016. Getting this endorsement from Oprah is a big accomplishment that should garner some recognition for the new brand.

Many of the newer online startups were created as a response to some of the offerings and business models that the traditional brands offered. I was eager to find out if Tempur Sealy would be able to compete with these brands through the Cocoon.


You can order a Cocoon mattress in two different levels of firmness direction through their website. You get free shipping with an estimate on when your mattress should arrive and it comes with a 100 night trial period. They even list 24/7 support which is something I have never seen before. The mattress arrives in a black box which gives it a sophisticated look and you can easily transport it to any room in your house to unbox. Below is a picture of the inside of the box upon opening. You get a fun picture in a frame:

Inside Cocoon


Below is a video of me unboxing the Cocoon mattress. I noticed this mattress took a little bit longer to come to form than other boxed mattresses. I think this is in part because the top layer of foam is a bit denser than others.


The Cocoon comes in 2 levels of firmness, a firm and a soft. According to their website, the cover is made of a stretch-knit fabric with spun poly fibers to make it breathable. They don’t list specific densities of their foams but the soft has 3 layers of foam while the firm has 2 layers.


I was able to compare both the soft and firm versions of this mattress. Which allowed me to do comparisons to help you decide which is best for you.

Here’s a picture illustrating sink in the soft version:

Cocoon Soft Sink

Here’s a picture of the firm version:

To get a sense of how they are constructed, I peeked under the cover of the mattress to show you how each layer reacts.

Here’s the soft Cocoon which has 3 layers:

Below is a video of the firm version which has two layers.

As far as heat retention goes, I didn’t notice much difference between the two levels of firmness. Below is a video shot with my infrared camera to illustrate heat retention:

This is the soft version:

Here’s the firm version:

Cocoon recently launched the Cocoon Chill mattress with a phase change cover below is a video showing heat retention on the Cocoon Chill mattress:


Finally below are some videos of me dropping a bowling ball on the mattresses to illustrate motion transfer. Again, there’s really not much difference between the two as the top layer seems to be the same which is what is absorbing most of the motion.
Here’s the soft version:

Here is the soft version in slow motion:

Compare that with the Firm Version

Firm version:

What I like best about the Cocoon mattress is the top layer. It is a very soft layer that conforms well and provides great pressure relief. Between the two, I liked the soft version the best. I really like to sink into my mattress and feel like it’s cradling every part of my body which this mattress does.

I don’t think this mattress would be well suited towards heavier people. I think a heaver set couple might find the base layer not substantial enough when first getting in the mattress. However, once lying down it should be just fine.

You can also buy the Cocoon on Amazon for the same price but without having to use the discount code. Just note that the return process may be a little more difficult because Amazon has a standard 30 day trial period vs. the 100 day trial period offered direct through Cocoon with free returns.  In this case I would advise buying direct from Cocoon.

              I think I’ve got too many tabs open on my browser looking at Cocoon, Lull, Purple, Tuft and needle, Casper, Ghost etc etc etc……Naturally like with clothes and so many products they are all aimed at Thin, skinny, small people…..I guess I fall in that category, though at 180 I’m far above the 140-145 I stayed at for years. So any suggestions for heavier people? At least in my case, me being “normal” and her being heavier…….These mattresses are all designated for what the world views as “normal” people.

                Hi Brian,

                At 180 the Cocoon will certainly work, no problem. I often recommend the Loom and Leaf for heavier people given it’s dense, firm foam. It is also a thicker than average mattress.

                HI Brian – i am 5’9″ woman weighing 218 lbs. I bought the LEESA mattress (Queen) a year ago and I love it. it doesn’t sleep hot…you don’t sink into it – but almost float on the surface. it is extremely comfortable and I am so happy I bought it. I have it on wooden slats – which came with the bedframe I ordered from Amazon

              I am 6’5″ and 230 lbs. Is this mattress not a good choice for me?

              • Ben October 18, 2016 - 9:40 pm Reply

                I think you should consider a thicker mattress. I suggest taking a look at some of the offerings from Brentwood Home

              Ok, I have to ask, what is considered “heavier people”. I wear a size 12 Petite, have curves, and am considered fairly normal sized by my communities description of “normal”. But, then again, a 43 year old woman that wears a size 5 and weighs 120 pounds in my neck of the woods would be considered for a trip to the ER to be evaluated for starvation. With that said, just what are you basing your normal sizing on? The comments above are kind of all over the place. In one answer, 180 will work fine; however, in the next one, a 6’5″, 230 lbs guy is too heavy. To me, the 6’5″ guy should be pretty thin, given his height. However, I could be looking at this completely wrong. By the way, is there a blog or website that has some sort of sizing chart for ordering these mattresses? Thanks so much!

              • Ben November 8, 2016 - 8:29 am Reply

                This mattress will be just fine for you. In fact I’m 6’4 and about 200 lbs. and I sleep just fine on it. I use myself as a benchmark for heavy which is very subjective but I need to start somewhere. I worry that someone over 200 lbs. or so would bottom out when plopping down into the mattress. This isn’t a deal breaker for most since when you lay on it you won’t bottom out but it is an indicator of the limits of the mattress.

              I have really bad back problems due to a accident. Which would you suggest to be the best suited? I’m 6’0 190.

                It’s hard to say, I usually recommend a firmer mattress for people with back problems so I would try the Firm version first knowing you can always return it for free if it doesn’t work out.

              Hello, on a scale of one to 10? how firm is the “soft” cocoon mattress?

              • Ben December 29, 2016 - 9:51 pm Reply

                It’s about a 7. Not terribly firm. What’s nice about it is the firmness comes from a very dense foam so even though it is, “firm” you still get good pressure relief.

              I might order the mattress, but I’m worried the soft might be too soft with very little support.

              Any input would be great.


              • Ben December 12, 2016 - 9:00 pm Reply

                The soft is probably an 8 out of 10. If you’re at all concerned about being too soft, I would go with the firm. Because it’s foam, you will still get good pressure relief.

              Help me out here Ben! I’ve been reading majority of your bed in a box reviews for months now. What’s the hold up you may ask. I’m 5′ 110lbs with major back issues and he is 5’9 and I assume nearly 200lbs no aches and pains at all. Is there any way that either the firm or soft could be a good option for us both?

              • Ben December 12, 2016 - 8:55 pm Reply

                I think the firm would be your best bet. However if you both have drastically different firmness preferences, you may want to take a look at the Luxi.

              Please help us make this expensive decision!!! Mattress reviews are so overwhelming. I have fibro, and sleep like the princess in the story of the princess and the pea. However, the super soft and comfy memory foam we currently have (possible sleep innovations?) leaves my husband and I both with HORRIBLE lower back pain. How do we get the correct support for our backs AND sufficient softness for presssure points? He is 6’3″, 250. I’m 5’2″, 170 (if that’s relevant).

              • Ben December 28, 2016 - 9:23 am Reply

                You should look for a mattress with a firm support base layer and then a soft top layer. The Cocoon firm would be a good choice but if you want something a bit softer but with good support consider the Amerisleep Revere.

              Can you use a heated mattress pad with a mattress like this?

              • Ben December 29, 2016 - 8:13 am Reply

                Yes. I have used heated mattress pads on my memory foam beds. I recently used the Eight Sleep smart mattress pad which allows you to turn it on with your phone.

              I have had the Amerisleep Revere at the top of my list for quite a while , but price has kept us from purchasing. Would you say the Cocoon firm is a close comparison? I am 5’2″ and 130# and husband is 6′ and 200#. we both prefer a firm feel.

              • Ben January 1, 2017 - 12:02 pm Reply

                It is close. I would definitely give the Cocoon a try first.

              I am looking for a firm mattress that has some softness (contouring) to it. I love the beauty rest hybrid luxury firm mattresses but they are insanely priced. I want a bed that I can sit on the edge and it not just sink like crazy (so good side support). I sleep on my side and back and my husband is a back or stomach sleeper. We are normal weights I think (160 and 210) but we have horrible problems rolling towards the center of the bed on our current (high priced) mattress. Can you recommend a good bed in the box for us? I tried sleep number with horrible results so I’m not inclined to have a bed with two different sides because I could always tell where the transition was to the other side of the mattress

                  What qualities does the winkbed have that you would recommend it over say the oceano?

                  • Ben January 1, 2017 - 9:34 pm Reply

                    The Winkbed will sleep a little cooler than the Oceano. The Winkbed is also considerably firmer than the Oceano but that is not a plus or minus it more comes down to preference. The Winkbed also has a little bit better edge support.

              hello Ben I’m a 54 y/o female who is very heavy who suffers from joint issues, my husband is a 55 y/o male who is also over weight and we are looking for a mattress that relieve pressure point pain. I’m a side sleeper and my husband is an all over sleeper. We are strongly considering getting two full beds. I’m through with beds made with coils. Please Please help us. I’m 5’5 inches and I weigh 250lbs and my husband is s5’10 inches and he weighs 230lbs.

                I would go with a thicker foam mattress to ensure that you don’t bottom out. I would give some strong consideration to the Loom & Leaf

              Does it come with a box spring?

              • Ben January 17, 2017 - 8:41 pm Reply

                No, but you can buy a box spring online. However, it doesn’t need a box spring. You can put it directly on a slatted base. I really like the Zinus slatted bases because they are affordable and look nice. Here’s a link to their bed which is extremely affordable. You can also find there standard base on the Zinus site as well.

                The Zinus bases and frames were awarded a 2016 Good Design™ Award for innovative design and manufacturing by The Chicago Athenaeum: Museum of Architecture and Design.

              Would you recommend firm or soft for a stomach sleeper? My current mattress has some sagging in it that is causing some lower back problems for me. (6’1″ 170lbs) Thanks!

              • Ben January 24, 2017 - 5:46 pm Reply

                They are actually both very good with support. This mattress skews firmer but I usually recommend a firmer mattress for a stomach sleeper so in this case I would go with a firm.

              I owned a Brooklyn bedding mattress which was lost in a split. I really liked that mattress at 6’6″ 250-280 depending on the week. How does the sealy compare to the Brooklyn bedding ? I also hate sleeping hot and heat transfer even on the chill model doesn’t seem very good for hot sleepers. If this is all foam and no latex I think I need to keep shopping.

              Unfortunately I’m looking for s slightly more affordable mattress than the Brooklyn bedding which while inexpensive isn’t exactly disposable. I will likely need a mattress for a year before leaving the country so is this one going to work in firm for my size compared to Brooklyn bedding or is there another mattress which costs less than the bb and contains latex ? I see a lot of options from $250-400 on Amazon but I can’t imagine they’re any good.

              From the research it looks like $800 is about as low a price as I’m likely to get on something that works for my size.

              I have looked into the Cocoon, Bed in a box, and Dreambed. I’m not sure which one to choose. I am 5′ 120 lbs and hubby is 5’9″ 135 lbs. We both suffer from back and neck pain due to an accident. He’s usually sleeps on his back or stomach. However I am a side sleeper 90% of the night, what would you recommend? If it’s the cocoon would you recommend soft or firm? Thank you for your time.

                I recommend the soft Cocoon mattress, I think it would be an excellent choice.

              Two questions: do you know the difference is size btwn the king and California king? Also, do you need to use a certain type of sheets? Thanks.

              • Ben February 23, 2017 - 8:28 am Reply

                A King is 76 in × 80 in while a California King is, 72 in × 84 in. With a Cal king you get a little more length which is great for tall people. However the drawback with Calforinia kings is that there are less choices for sheets and bed frames.

                You can use any sheets on this mattress. You can find all my sheet reviews here.

              Thanks for such a thorough review of the Cocon. Does this mattress offer any side support. I am a side sleeper that sleeps close to the edge of the bed.

              Thank you

              • Ben March 17, 2017 - 7:51 am Reply

                It does have some side support but not as much as others. Since it is an all foam mattress it will sink in a bit. That said, because it is a denser foam, it will conform more to your body than other mattresses so it will keep you in your ideal sleep position which means a lot less tossing and turning.
