Cushy support - Mince Pie

Just what I expected but I might need to exchange it. I bought the soft mattress. It feels like foam on a rather firm, supportive mattress. Sounds ideal for a side sleeper, but I'm waking up a bit sore in lower back. Honestly, it could be my medicine dose. I have to do a good trial with better pillows, regular dose of my medicine to be scientific. Arrived a day early. I managed to unpack it on my own. I'm a short woman with back pain and I didn't hurt myself unpacking it. It would be super easy for two people. I'm very happy i can exchange it if i need to.

I No Longer Wake Up Every Couple of Hours! - Suzanne L.

The process to buy the mattress was so painless. It was so much better than stepping foot into a mattress store - I will never do that again. My husband threw his back out and we desperately needed this new one. So I called customer service and told them what happened. They were SO helpful and actually over-nighted the mattress to us so my husband could recuperate faster. I am very grateful. One thing to note - even though we have the "soft" version, it is much firmer than what I was expecting. It's not one of those foam mattresses than can be difficult to move around in. This definitely has a good amount of firmness to it. Even my husband, who loves a good, firm mattress, says this is great for him!

No more pain in the morning - Jeff

For the first time in months I wake up rested and NO back pain.

Very comfy - Jen

Still enjoying a great nights sleep on this mattress! Seamless process from selection to delivery to set up.

Love our new cocoon! - Angela Donnelly

Delivery was timely, package was easy to open, mattress came to life immediately. Our mattress is firm and comfortable. We love it!

Amazing bed - Dani

The morning after sleeping on it, I got out of bed and starting saying, "My back hurts." As soon as I said it though, I realized it wasn't hurting! I was just so used to complaining about my back hurting that I did it automatically without even thinking. It keeps me very warm a night!

I'm diggin it - Khaleesi

I've only had my mattress for about 2 weeks now but so far I'm happy with it and am definitely sleeping better. It really is more firm than you would expect out of a "soft" mattress but it's actually what I prefer. I feel like I have more support that way. My best friend has a Leesa and my Cocoon is definitely a bit firmer than hers. I've bought foam toppers in the past and they never held up over time. I am hoping this foam mattress doesn't let me down. I have to say it is a really good deal compared to other bed in a box companies out there and the reputable company name sold it for me. Of course the great reviews helped too ;-) I plan on updated my review in the future to let you know how it holds up over time. Good luck, friends!

Ordering them for every room - Laura

We love, love our new Cocoon mattress and foundation. I don't want to get out of bed! I'm now ordering them for our son's room and our guest room, too! Great customer service when I reached out with questions.

Just what the doctor ordered! - Harry H

What an awesome mattress. The only thing I would suggest re: the cocoon would be to unpackage/wrap it on the floor completely before putting it on your bed frame. You have to take it off to get the last wrap off anyway.... Money well spent, very worth it, we will see how it holds up in the next few months before we come back to update our comments.

Nice design and easy to handle - Huan

I just wish it is firmer. However, the piece is not firm enough for me so I have to return it.

Best money I've ever wasted! - Josh P.

This bed is very firm. From my personal opinion, I would give this bed a 7.5 out of 10 on a firmness scale. This bed causes me to wake up with back and neck pain, that I did not get from my older SPRING mattress. As for the "chill" cover, it does make the mattress feel a slight bit cooler to the touch, but after 15-20 minutes of laying in bed, you can kiss that coolness goodbye!

Enjoying a good nights sleep - Sleeping Better

Thanks for the great bed.

A better nights sleep. - Randy V.

The Chill Soft mattress was a great purchase, as it has given me a better nights sleep during the day, as I work nights. I have had problems with other mattresses, due to back aches from work, but the Chill Soft has helped ease my back pain. The Chill Soft does seem to sleep cooler than my old mattress, though not as much cooler as I wish it would be.

WE LOVE IT! - RITOG

I bought 2 twin for my kids and they loved it! Firmness is just perfect. We currently have a Serta bed that we paid over 2k, some spots in the bed are now too soft and the edge support is really bad. Tried to claim for warranty but it seems like they're doing everything they can to not cover it. NO MORE SERTA FOR US!

Cool and FIRM - Kari

The mattress is very comfortable and keeps my hot sleeping husband cool as advertised. It is on the firm side of firm but otherwise we are completely happy with our purchase. The delivery and set up were super easy, too.

Sleeping Beauty - Eric C.

I am a very sensitive sleeper, but once you lay on this bed you go off to wonderland! Usually, I get up several times during the night but with this bed, I'm dreaming and or sleeping until morning. The con is sometimes my ears or shoulders are little sore from being in such deep sleep but your body gets used to it and adjusts. Now I can't sleep on anything else. What am I going to do when I travel now?

Easy and Comfortable - Side and back sleepers

Mattress arrived on time and was easy to open and set up. It is very comfortable both for me and my husband.

Love it !!!!!! - Mark arnold

Wish I would of bought one sooner . Haven't slept this good in years!

Love is sleeping on a Cocoon - Sleeping like an Angel

So easy to purchase. So easy to unbox and unpack. So easy to place on a boxspring. So easy to sleep on from the first night. My Cocoon is the best bed purchase I've made.

Not a 5 because.. - She's So Sensitive

Great mattress and I feel the wooden slat in the foundation.

Restful sleeping - Idongacha

First night was kind of rough but I think my body was adjusting to the new bed. After a few days of breaking it in I found that I'm more refreshed and limber with no more back pains. I would recommend this bed to anybody who's in the market looking for one.

Great mattress!! - amanda c

I love everything about this bed super easy to put together and the mattress is so comfortable. I got the chill king mattress best decision, I couldn't be happier!

No more pain - Josie

This is my third cocoon mattress. I initially purchased one for myself a year and half ago, I love it so much that I bought my mom a cocoon classic and a cocoon chill firm for a dear friend who was having back issues. They both love it and their aches and pains are gone. To top it all, unparalleled customer service.

It's a great bed - CLK

I purchased this bed back in March 2017. It's now November. I love this bed now but I didn't love it when I first purchased it. I felt it was as too hard even though it was the soft version. However, my husband really liked it so instead of returning it, I bought a memory foam topper. That helped immensely. I now get amazing sleeps. I would definitely recommend this bed. The price was good as well as I had a coupon for $100 off.

Loved the Coolness - Angela H.

The mattress cool at night. It is also very comfortable and great on my back.

Almost perfect - Maura B.

Great support. Keeps me cool and comfortable. Best purchase I made last year. My only criticism is that the edges of the mattress are strangely too soft, softer than the rest of my firm mattress. It is too easy to slide off the edge when one sits to put on shoes. Otherwise, best mattress ever!

The most comfortable bed in the gouse - Alison K

We recently got the cocoon soft mattress for our daughter. It is hands down the most comfortable mattress in the house and is great during story time.

A great night sleep, finally! - Sleepy One

Love how cool my mattress stays and its amazingly comfortable that i don't want to get up in the mornings.

Love it! - Sleeping Beauty

Our new bed is so comfy! I have been happy with it since day 1. Ordering was so easy and so was set up. I will definitely buy another one for our guest bed.

nice but it smells - I hope it works out.

I like the bed, but unfortunately it smells pretty bad hopefully the smell does away. I slept on it the first night and the next morning I felt dizzy. maybe it was the weather outside or something, but it could of been the flumes from the bed. I would suggest to anyone who buys this that they put it in a room after it has expanded and let it air out for a week. who knows maybe two weeks. I ordered a firm mattress, but maybe I should of ordered a intermediate. I don't get into it and say aww that is so comfortable.

Super comfy and super affordable - Flo

It was so easy to get this delivered to my new apartment and I didn't have to wait for delivery men. The mattress is comfy and afforable.

So comfy! - Kari H

It took a bit to get used to the difference in a foam mattress compared to a typical spring mattress. After the initial few nights of getting used it, I can't wait to crawl into bed at night!

Finally a good night's sleep! - John

We always purchase a firm mattress and this mattress is the firm we desire! The customer service agents are very helpful in answering any questions before purchase. It shipped quickly and was easy to set up. Thank you Cocoon for giving us a good night's sleep!

Soooo comfortable!!!!!!! - Snuggled in---in Kansas

The way it's made and the ease of ordering and receiving it. The thickness is great, easy to get in and out for an elderly person.

Most comfortable nights sleep EVER!!!! - Raescar1

I Love that I feel like I'm getting a full body hug while I sleep! Not too firm, not too soft, a perfect snuggle!! Love it!

"Best Guest Mattress" - every guest - K. Hillestad

I bought this mattress to put in my spare bedroom. Since purchase, I've had a few guests stay over and tell me how great the mattress is and that they were surprised I sprung for one of those -pedic mattresses that cost so much money! I tried the mattress out for myself one weekend, and decided to order a King for my bedroom. I usually toss and turn at night, but woke up in the same fetal position I laid down in the night before.

comfortable - Cathy

a comfortable mattress but soft feels too soft to my standard. Would be better if there is another choice between soft and firm!

Over the moon happy w/ my Cocoon! - Miami Beach sleeper

The delivery process, unfolding and making the perfect bed to fall asleep in....I love this mattress and really pleased with the right amount of firmness for the "firm". Not too hard, and definitely not too soft--just RIGHT! Thank you Cocoon for making my nights better :)

Finally a great night's rest! - Defiant

Comfy. Sheets don't stay on well. Best sleep I have had in a while. Don't have to have my back popped back into place every day anymore.

LOVE THIS BED!!!! - Lee S.

Bought this bed after doing extensive research on different brands. The Cocoon bed came out a winner, far ahead of the others. My Cocoon bed was delivered promptly and set up a super easy. This is hands down the best bed I have ever slept on. I love this bed!

NEEDS GOOD FOUNDATION - dont use bunky board!

We bought this mattress over a year ago...had no idea that they sold a separate foundation. Spent months replacing the bunky board we got from Crate and Barrell 2 times and dealing with back pain, even called the mattress mfr. The mattress mfr said they recommend their foundation instead of bunky board. Ordering it today, hopefully it will take care of the problem but paying $50 more than if I bought them together from the start. They need to update the description and recommend the foundation if they don't buy it separately OR don't even sell the mattress alone. Description said it needs a 'solid' foundation...what does that even mean? I had a hard time trying to find a bunky board that is solid wood from many retailers. Crate and Barrel's new bunky board is made of compressed cardboard! A painful process, but I like the mattress.

Works well for us

The mattress is definitely on the firm side but we both find it about right. After 11 months, the bed seems to be wearing very well... no signs of change in feel or shape. The adjustable bed is used in zero gravity every night for one of us and not used at all for the other. The adjustable bed works well for back sleepers but not side or stomach sleepers.

Six years later, we still love it!

This bed is the best we have ever slept on, even 6 years later. We have the queen, and now want a Cali king (we now have a dog sleeping with us), and will be buying another one of these latex matresses from Costco. This one will go into the guest room, and it looks brand new. It has not settled or sagged at all, even though it is used every night, by 2 people. It is NOT hot, either. The memory foam mattress we bought from Costco first, was hot, however. So we returned the memory foam and got this latex mattress. We are so happy!!!

Not so great!!

I did what i thought was plenty of research before i bought this bed.. I've waited a full year to try and get used to it, and kept telling myself and my spouse it would get better. Not only was it hard and uncomfortable but, from 3 months on, it had big depression on both sides. It seemed to get worse , not better! The only good thing is i bought it from Costco, so they agreed to take it back, no problem! Yea Costco!!

very good customer services

I bought this bed on July 7, 2016. It was my first Costco online shopping. As in warehouse shopping, the online service was very good. The delivery company did not call me to confirm the delivery time but Joshua and Carlos did great in the delivery of the bed and setting it up. Brandon at the distribution center was excellent. I could test the bed before the purchase. The latex mattress feels cool in summer compared to other types of mattresses. I hope I enjoy my bed for many years to come. I love shopping at Costco!!!

Super Comfortable; great support

I've purchased 3 of these mattress so far. The first one about 3 years ago, then another one the following year and another one a couple months ago. the first one was in a guest room and the other two were for two of my kids who loved the bed when they slept on it while visiting!

Helps with my back

I bought this bed over 2 years ago, maybe 3 years now. My husband was a reluctant buyer, because we are only early 40's :) He thought adjustable was for the nursing home. But he had enjoyed it just as much. It hasn't helped his snoring, but he enjoys the leg elevation and massage features after a tough day or workout, and elevation of his head when congested. I have had a couple of back injuries from car accidents, and sleep considerably better on this bed than ANY OTHER!! We had a memory foam before this. This is NOT memory foam. Memory foam sinks in with your weight, then when you turn over you fall back into the rut you created. Ours was also hot. This foam doesn't radiate heart back at you. I love that! It doesn't sink in. It has great support. It is nice to be able to sleep elevated without getting up in the middle of the night to prop up or go to the recliner. My bed sleeps just like it did almost 3 years ago. No sagging, indentions, or soft spots. It does creak a little when adjusting, nothing a little wd-40 can't fix. The base and massage features still work like a top. No problem! Good buy!

L-O-V-E IT!!!!!!!

Purchased and received this split King organic mattresses with adjustable bases on April 8th, 2016. What a great product! Both my husband and I absolutely love our mattresses! The adjustable bases fit perfectly inside our existing bed frame, and the mattresses are sooooo very comfortable. I have always been a side sleeper, but no more! I'm able to easily sleep on my back now. Since I am a professional singer, this is a real plus for me. Also, the adjustability allows me to (among other things) raise my head ever so slightly to allow for sinus drainage as well as legs for additional perfectly tweaked comfort. The mattress cover is soft and also feels luxurious. A 3 inch layer of softer 19 ILD natural latex perfectly compliments the firmer 32 ILD layer underneath it to softly cradle with no pressure points yet support my body superbly. Adjustable base works great. Fully articulates for customization. Zero Gravity pre programmed position is heavenly! Don't wait. Buy this now!!! You'll be glad you did! Great price and great product. Thanks Sleep Science - Well done!

Wonderful Bed!

We got this bed a couple of months ago. It is very comfortable. Unaware another person is in the same bed. Mattress is fine for us, not too firm and not too soft. No odor.

Delivery company had great personnel.

One side had a control box (located under the bed) that failed in the first few hours. Costco called the company and we had a new one installed by the company in a few days.

I would suggest going to check out Dreamfit mattress covers (they come in twin xl and their kings sheets (2 twin xl bottom sheets with one King top sheet. Their bottom sheets and mattress covers have extra elastic straps to hold the sheets in place. I found these after much research. They stay in place great. Love my bed!!

Comfortable..natural latex adjustable

The mattress delivery was great..even on time. The mattress itself is nice ...no sinking in like foam. Soft and supportive. The adjustable base is great. I do wish the lights on the remotes would come on before you try to poke the right button. Zero gravity setting is awesome!

Very comfortable

Its very comfortable. Firm for support but not too firm. My wife & I think it is the best mattress we have slept in. No smell at all.

It's SOFT, not 'medium with a bounce'

Disagree with the SUBJECTIVE product details 'Sleep Science comfort scale: medium with a bounce.'

There is missing objective ILD firmness scale info in the product details. For me, 5'3 and less than 120 lb, this is surely a soft latex mattress. In general, The 'soft' designation corresponds to an ILD rating of 19-21. The ILD rating for the medium range is 24-26. After digging yourself, then you find this mattress has ILD 19 on the top 3 inch layer over another 6 inch of 32 ILD.
