This mattress is comfy! It's not too firm and not too soft. I love it! I was a little nervous before I bought it because the price is so low. Once I went in the store and tested it out, I knew I was going to get my monies worth. Granted I've only had it for about a week now, even my boyfriend has confirmed it's super comfortale. Get it while it's on sale.View More Reviews
I bought the twin mattress and much to my dismay there was about a 4 inch gap between the mattress and my bed frame. After measuring the mattress I realized it was only 36 inches wide, not the standard of 39 inches (despite the website listing it as 39 inches wide). I finally got a hold of the manufacturer and they said that their twins are "intended" to be 38 inches wide but that each one can differ by up to two inches. So you're basically left with a mini-twin. I will be returning this.
It's pretty comfy for the price but honestly I could have gotten cheaper at another matress store, definitely shop around more. It's not very thick and the euro top seems like it will be flattened very easily I give it maybe a year before it starts losing its comfort completely
My first set of guests found this to be very comfortable. I slept in the guest room to try it out and found it very comfortable. I am very pleased with this purchase and will purchase future items.
Nice product at the right price. My child needed a mattress for a new college apartment. We saw many options and even ran into a manufacturers rep at the store who helped us with good advice. As usual, the experience was great
love this mattress very comfortable the never disappoint
Great price and such an amazing mattress. The level of comfort is undeniable. I'm very happy with this product and would recommend it in a heartbeat.
This mattress was purchased for a bedroom that is only used for guests and when child is home from college. The mattress is very comfortable and the price is perfect for this situation. We have had it about a week and my kid loves it, it's 12:20 pm now as I write this review and she is still sleeping.
Buying this mattress was an amazing investment. Such a comfortable bed to sleep on and the service and delivery was very prompt and professional.
Very happy with what I bought slept like a baby. The delivery guys came set it up fast. Very happy with the service.
My husband and I are sleeping so much better since purchasing this mattress. It's not too firm or too soft, so you get support without feeling like you're sleeping on a board.
We love our new Mattress! The comfort and quality is unbelievable and for what we paid for it...we just love it!!
I purchased two of these mattress for my boys, without them being there to try them, and they just love it. They said it's so comfortable that it just conforms to their bodies. Mind you my 15 year old is 262lbs and said the bed is like a giant blanket. So hats off for a great product at a reasonable price...
I recently stayed in a bed in a breakfast in Maine--and loved the mattress I slept on. (I've got neck and shoulder issues to the mattress is often crucial.) I found a similar King Koil mattress and Raymour and Flanigan. The price was right; the delivery was prompt. "For this relief much thanks." Happy with my purchse: feels good!
When choosing a bed we needed a firm mattress with back support for me but yet some cushioning for my husband and the King Koil Perfect Response Elite Lakeside Pillowtop was "the perfect" choice. Very pleased with our decision and we even received next day FREE delivery - very nice!
I love my new mattress -and the service that came with it.
The bed is great. It came when they said it would and the sales person was wonderful in working with our family.
Bought this for my guest bedroom and it was given an A plus By my first guest. She couldn't believe it was a firm mattress. Would highly recommend.
WE NEEDED A FIRM MATTRESS AND THIS IS PERFECT! NOT ONLY IS IT EXACTLY WHAT WE WANTED THE INSTALLATION WAS WONDERFUL. WE NEEDED SLATS FOR SUPPORT AND THE DELIVERING TECHS DID IT ALL WITH NO PROBLEM. SALES PERSON WAS WELL INFORMED AND ANSWERED ALL OF OUR QUESTIONS. FLO L
I have a California King Mattress and it is the best.... I was not sure of down sizing to a Queen Mattress, but I must say that it was the best choice I love the way my body rest and the best part is that my husband and I are know closer....
THE MATTRESS AN BOX SPRING I PURCHASED WAS JUST EXCELLENT. ITS MEETS ALL MY STANDARDS FOR COMFORT .THE SALES PEOPLE WERE JUST GREAT HELPING ME FIND THE RIGHT ONE . I HIGHLY RECOMMEND MY CHOICE.AND THE STORE LOCATION ON CROPSEY AVENUE
It's hard to get out of bed after sleeping on this very comfortable mattress. You look forward to relaxing at the end of the day. I like it very much. Keep in mind, coupled with the box spring, it is very high. Can't go wrong with this one, unless you like it extremely firm. It has the right kind of firm but soft too.
Very happy with our purchase! Bed is comfortable. Not too firm, not too soft. Great quality for a great price!
The mattress is very comfortable. It's the best sleep I've had in a long time. It is a 5 star hotel quality mattress. I'm in love. I must stress that the hubby that works at night and have Insomnia also agreed that his sleep has been much better. Thumb's up.
I absolutely love my new bed. Best experience it's comfortable for my back after I come home from work cause I work 19 hours of the day doing labor and I just needed a new way to sleep. This is one of the most comfortable beds I've ever slept in and I highly recommend it to everyone.
The store was great the product was well priced and it was a convenient purchase. Loved the salesmen [Associate name removed].
This mattress has just enough firmness topped with a pillow top that has just enough softness! The price is perfect and the customer service was out of this world. No one trying to force me to the most expensive products in the store.
I am very much enjoying my new mattress. I was afraid it might be too soft but I'm glad I went with the softer mattress over the more firm mattress. While this is soft, it is still very supportive. This mattress is great quality for a good price.
great mattress sleep like a baby love it so much it is great
Best decision i made for my son he loves his new bed. Raymour and flanigan alway have good quality furniture which last a long time. I know when i shop with them im getting good stuff.
I needed a mattress for my fathers spare bedroom so I had a place to sleep when I visited. I didn't want to spend a lot but I wanted something that was nice and comfortable. This mattress is it! I have slept great when visiting him now and the Sales associate Tom P. in Clifton Park listened to my needs and took care of everything! Thank you Tom!
very comfortable but still with support!! Very happy!!
This mattress was purchased for a guest room and has only been slept on once with a report that is was very comfortable. The salesman was very helpful and polite. The delivery team were very helpful and delivered quite timely
I really like this mattress. It's really comfortable and it feels like I'm sleeping on a cloud.
My old mattress was still in good looking shape, but had outlasted the years I needed an extra firm mattress. My new King Koil plush is so comfortable, I sleep right through the night. Both my husband and I are well pleased with this purchase.
Mattress is unbelievably comfortable. My wife and I love it so much.
So far so good! Great price for the quality. I'll write another review after about a month or so
I am so happy with my purchase. I haven't slept this well in a long time. I definitely Recommend this mattress. The salesman was very knowledgeable and he listened to my needs.
I am very happy with my king coil mattress purchase. In the past I have always bought Sealy's. It is very comfortable and I am happy with it. Also the service at the store and the delivery was very good. I am also very happy with the guarantee on the mattress.
Mattress after the first night of sleep had a indentation in it already. Was or is not as comfortable as I expected.
I cannot rave about this mattress enough -- very comfortable, non-toxic materials I can feel good about (and I am very picky about everything I buy in terms of toxicity), and what a total STEAL! I had been searching for mattresses for ages, and I could not find anything I wanted for a price I could afford until I came across this one. No off-gassing, but there is a very faint, not-at-all-unpleasant, earthy smell to it. And it was delivered very fast, way before the promised time frame. Lastly, the mattress was not nearly as uncomfortably hard/firm as some of the reviews indicated. I actually wish I had not bought the expensive latex topper I already purchased elsewhere, because it really doesn't even need it. I was a little nervous about buying a mattress online, but I am SO happy with this purchase.View More Reviews
My wife is a Naturopathic Doctor and understands the importance of a natural mattress and insisted we buy one for my daughter when we moved her out of her crib. I was hesitant since these are so expensive, but she explained that sleeping on a mattress that is not natural means that her face is pressed up against chemicals and toxic off-gassing for an entire night. This was a huge concern so we searched high and low for a high quality natural mattress that would also provide her with a good night's sleep. We went to a local store that specialized in organic mattresses and could not find anything that felt good (they felt flimsy) and they were all so expensive. I decided to search online to see if I could find something and luckily I found the Echo Mattress.
We purchased the single sided Echo Mattress for my little girl and we absolutely LOVE it. It is super clean, no smells at all, and very comfortable. It came packaged rolled up and was super easy to bring upstairs and unroll onto her bed.
Now when I read my little girl bedtime stories I end up staying in bed with her a bit longer than I need to so I can enjoy her comfortable bed. I was actually enjoying my little girl's mattress better than my own so we decided to buy a King Size double sided version of this mattress for my own bed.
This is an incredible bed an a wonderful price and the customer service in this place is amazing too!
When I started waking up with back pain on my 8 year old Beautyrest mattress, I knew it was time to get a replacement. I wanted a 'natural' mattress that was free of flame-retardants and off-gassing chemicals, but most of them were way out of my price range. I found this one on Amazon and read all the reviews. Something to note: at the time of this writing, there are currently 18 reviews with an average 4 1/2 star rating. However, half of those reviewers specifically say that they purchased this mattress for a young child so they are not reviewing it from an adult's comfort perspective. I'm going to tell you right now, this mattress is firm. Very firm. Another reviewer likened it to sleeping on a bed of rocks, which is not far off. I would say it's more like sleeping on a carpeted floor. When I first started sleeping on it, I was very disappointed--it was so uncomfortable. I should add that I have a 2 inch latex topper AND a featherbed on top of it, and it's still ridiculously firm. However, after sleeping on it for seven weeks, I have gotten used to it. I am no longer waking up with back pain and I'm not breathing in toxic chemicals. Taking into consideration price, convenience (free ship/rolled up), and natural components, I would say that I am happy with the purchase. Just know that you're going to have to put some sort of topper on this mattress--I can't imagine any adult being able to sleep on this with no cushion.
The mattress arrived quickly and in good condition. We did not have any problem with the firmness, and thought it was comfortable support. My problem was with the mattress fibers/ stuffing. We let it air out for a week before putting in on the bed. Although my spouse did not notice any smell, the mattress did give me a stuffy nose every time I laid in it for about a month, even after changing out the mattress pad and sheets. This finally went away after a few weeks and I am able to enjoy the mattress now.
We were looking for a healthy alternative to our other mattress that wouldn't break the bank and would be better on our backs. We had looked at other organic mattress that were 6 times this cost so when I found this one I was estatic. This mattress has far exceeded our expectations. It is so comfortable and we don't wake up in the morning with terrible neck and back pain. Some people have complained about how hard it is, however we never experienced that. I do enjoy sleeping on the ground from time to time as it helps my back feel better so I am used to firm sleeping spaces. At first, when you open it and unroll it or does have a strong wool smell but it's nothing obnoxious and it does go away in a couple days. We have been sleeping on this mattress now for a couple months and have felt the improvement and I love knowing there's no off gassing and I sleep easier. I would highly recommend this product for anyone looking for a more budget friendly organic mattress!
I really, really wanted to like this mattress. We are very careful with the products we buy, to make sure everything is healthy and get the best for ourselves and our kids. I got this mattress in King for myself and husband, and 2 Twins for my kids. I knew it was going to be firm, but damn! It's just not comfortable. I wanted to like it, I really did- tried everything, spent more money on toppers than I ever imagined I would. I got a very fluffy lofty topper, it didn't help. I got a wool topper, still nothing. I had a firm before, but this mattress is TOO firm, I sleep on my side and have curves, it just puts pressure on my joints. Now I'm stuck and unhappy. The kids are light weight, and I got them toppers too for added comfort, but due to how they sleep- it seems to be ok for them. As for me, I'm wishing we didn't get rid of our memory foam mattress which was a lot more comfortable. We only got rid of it because we wanted to clear the house of toxins. I really, really miss that mattress. Can't afford another topper to try, or a new mattress at this time.
too firm for our taste
Like it but cant get rid of smell for month. Waiting for summer to put it on a direct sun again
What can I say, I LOVE this mattress ! It's firm without being hard.
AMAZING. This mattress came in a roll and so was really easy to maneuver onto the bed and then cut open. It is soo comfortable our daughter loves it.
I did not realize when I purchased this mattress that it is only 'one sided' but unfortunately it is and it is extremely hard. I simply would not purchase another one like this.
I don't write reviews, but we bought this mattress for our daughter and she has slept so soundly on it! Knowing what we do about off gassing and what conventional mattresses do to our bodies, we knew we had to go with this company and ultimately this mattress! Thanks again for your stellar product!
I was a little concerned about all of the reports of the smell of the mattress. When we unpacked it I didn't smell anything but when I put my nose right against the mattress and inhaled I could smell a very tiny smell that my son said reminded him of Play doh. I think it's actually the smell of the plastic that the mattress came in. If I had not been looking for the smell I would not have noticed anything at all.
This was just delivered today so I will update later. The box was quite beat up, but the mattress inside was clean (wrapped in plastic). Upon opening and unrolling there was no chemical smell: one person said 'it smells like granola' and another person said 'it smells healthy'. Three adults (of very different sizes and weights) each lay down on it (separately lol) and each found it comfortable. It is medium firmness, not hard.
most comfortable bed in our house. my father in law now kicks my son out of his bed when he visits
This is the most comfortable mattress I remember ever sleeping on. I was sure after reading previous reviews that I would need to purchase a topper to make it more comfortable, but I love it just the way it is. I sleep better than I have in years.
My spouse and I love this mattress. We've had it for about 5 months now and sleep very well on it. It's not too firm but firm enough that it won't give you back problems. It did smell a bit like wool or barn when we first got it but too the mattress' defense, I was in my first trimester of pregnancy so everything smelled to me. I aired it out in the sun for two days as the company advised and it really did help. I feel really good knowing that I sleep on a healthy mattress. I plan on buying another one.
We were looking for an organic mattress, and this one was an excellent price. That being the case, I was not expecting to find such high quality! I am very happy with this mattress! It is very firm, which I like because it has really helped my children's back issues to be sleeping on a firm mattress, yet it is still comfortable. It seems sturdy, well-made, and I have high hopes it will hold up well as my children grow up. It had no odors other than the cardboard and exterior packaging, arrived quickly and was packed all rolled-up- so it was very compact and relatively easy to transport, considering it is a mattress! I was so pleased with the purchase of the first mattress for my son that we have purchased a second for my littlest, who sleeps much better now that she is on this mattress, interestingly enough. I highly recommend this mattress and will be purchasing a third mattress after the baby on the way is big enough for a bed. Many thanks to the company for offering a quality product that is free from chemicals, well-made, and very reasonably priced.
We purchased two of these mattresses in the twin size for our four year olds. They are not super comfortable but our children seem to like them. I probably wouldn't buy them again but time will tell how well they hold up.
Matress comes rolled up and pops out like a roll of biscuits !!! Places a matress topper on it and it is money !!! Very happy with the purchase
Love it. I bought another after the first one came in, very comfortable!
This mattress is better than I expected!
t smells gross, with a really strong chemical smell that comes through the bedding even six months later. I am worried about having my child sleep on it and am considering throwing it out. I don't know what the smell is but it can't be anything good. I should have known that the price was too good to be true.
I needed a mattress that wouldn't make me swell up from all the chemicals on it. So many were expensive or didn't look very comfortable. I eventually took my chances on this one. I was concerned about the mention of smell because I am very sensitive to smells. I even called the company to ask if they could air the mattress out for a few days for me. I wasn't patient enough to wait the first time for them to answer because I needed a mattress soon but an unfortunate event turned into a fortunate result. When the bed arrived, FedEx had an accident with the package and the bed was no longer sealed inside the packaging. I called the company and sent them pictures. I called FedEx and they picked up the mattress. The mattress company remembered me and before getting the mattress back, they started airing a mattress out for the 3 days that other reviews mentioned. They sent the mattress to me before even getting the mattress back. BTW, the smell reminds me of Cheerios in case you wonder what it smells like. This mattress was just made right before it was sent to me so it is very understandable I could still smell a little of the materials. I have had it for less than a month and I sleep well. I don't wake up swollen. I am so happy about that. I have arthritis and I wake up stiff most of the time with the old mattress. I barely ever have problems with this new mattress. I got organic sheets too. The bed is firm, very firm. I like soft beds but the firmness doesn't bother me at all. The bed is wool and cotton. There isn't foam so there isn't much to make it fluffy but I figured if I had a problem, I would get a mattress topper. I don't need one though. I am quite comfy in this bed. This is a great mattress with great employees. I would highly recommend buying one.
The bed is perfect medium firm and very comfortable. It does not have any odors and delivery was fast. Highly recommend.
I switched to this mattress after sleeping on a premium organic latex mattress from another company that cost nearly $3000 and sank terribly in the middle after only a handful of years of use. The Natural Escape feels extremely high-end in its materials and construction, and I adore the perfect medium-firm density. Such a reasonable price point for the unquestionable quality (not to mention the fab company philosophy!) I now own two�one for me and one for my toddler son.
Very comfortable without the sunk in feeling of memory foam, great edge support and I didn't feel hot like with some mattresses. Outstanding customer support that handled everything quickly and professionally.
This is the most comfortable mattress I�ve ever owned! Customer service was very helpful and nice, and it didn�t smell at all when I unpacked it. Would highly recommend!
I’m chemically sensitive and have bought three of these mattresses in the last two years. I love them.
We’ve only been using it a week but I’m happy so far. My hip pain more or less went away after the first night!
My family and I were in the market for a non-toxic mattress. We had been doing a lot of research because we have a new baby. We compared options and we came across Mygreen. We were skeptical about a mail ordered mattress. But, we have been pleasantly surprised by this wonderful mattress. It has a lower price point than other natural options. No adhesives. Non-toxic materials. It is very comfortable. It has very faint earthy smell to it. I will recommend this company to all of my mommy friends and family. We love it! Thank you for a healthy nights rest!!
This is the best mattress I have ever owned and has given me the best sleep of life over the past three years (and still going strong). My wife and I are about to buy our second for a guest room.
Love this mattress. I salute with the middle of five, the other chemical bed mattress companies along with the satanic government agencies that mandate the use of chemical fire retardants. Because you never know when you might spontaneously combust into flames during your sleep. In any case, this mattress is amazing. And not being forced to sleep on cancer causing chemicals is well worth the price.
I researched organic mattresses for weeks prior to purchase. My Green Mattress was the Best Buy based on price and comfort for combo sleepers like my husband and I. We also bought the topper for additional softness. We are very happy with purchase. Highly recommend.
Our whole family loves how soft and firm this is, depending on your perspective! We even changed over from memory foam topping over our last bed, and found this mattress to be a downright good quality bed. I personally love the intention of the company and the �cleaner� product compared to other beds/companies! Would definitely buy again!
Nice mattress! We like that the quality and safe materials this mattress is made of. There were no smells upon opening the box. The price isn�t cheap, but we are happy with the product. It is firm, but our backs feel good!
We've been sleeping on this mattress for a couple of weeks or so. My spouse says it's "fine", and a great improvement over our previous, worn-out foam pad. I've had serious back troubles all my adult life, and am utterly delighted with it so far. I was waking up every morning with a lot of back pain, all gone now. I really hope this mattress continues to work this well!
My husband and I absolutely love this mattress! We love how it feels but most importantly we love the quality of it. We sleep better just knowing it does not contain harmful materials and its all natural. Great costumer service and fast delivery. Worth every penny!
Huge fan of this mattress! Easy to put on my frame and fits perfectly! I love how comfy it is!
