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’ve bought two of these mattresses. Excellent quality, super comfortable, and absolutely no chemical smell. I’ve spent 6 months researching mattresses with concerns about health, comfort, and quality. I finally decided on the organic latex. I found this to be the cheapest site to buy from (despite the fact that I live in Canada). We are planning on buying 3 more, as we are a family of 6. It’s the only mattress our family will ever use and the only one I’d recommend without hesitation.View More Reviews
We purchased a full mattress for our guest room. This company is the best! Excellent customer service, shipping, packing. Mattress is super comfortable and has gotten rave reviews so far.
We purchased our dream vacation home, so we wanted our dream bed. We purchased the exact same king set up that we have at home. It’s so comfortable, we just love our bed and now there’s no getting used to a different mattress. Shipping is very quick, and easy. We also purchased the new Roma Mattress for our guest room. Our first guest said it was great!! I am constantly recommending SleepEz to anyone who will listen. Thanks SleepEz!!
Best Ever with the option to change firmness once you order it. Your never stuck with what you thought you wanted. Great customer service, friendly, helpful people who only want to give you a great mattress buying experience! Larry Kitchens in Norfolk Virginia
This mattress system is truly amazingly comfortable. As someone who had no problems sleeping on my 20-year old mattress, I can attest this is incomparable and that I sleep even better. Before I would have a few minutes before falling asleep, now I am out almost immediately. Combined with silk and linen bedding, it is such a luxury and comfort. The mattress came in three boxes and was simple to set up. The video on the website is helpful. Basically, you spread the organic cotton and wool cover on your bed and assemble the mattress components based on your preferences. The system is very versatile, with different layers and firmness can be combined. In addition, for queen size and larger, each half of the mattress can be different. It is a really amazing experience to sleep on this mattress. I also got full bedding and several pillows made of the same awesome latex. I fully, highly recommend it from personal experience.
First time user of latex mattresses. So far this has been a great experience. Sleep EZ Customer service is great too! Those guys will work with you in resolving any issues and their recommendations are noteworthy as well.
I love my new mattress! No more back pain.
I bought 13-in Natural Latex Mattress with All Talalay layers (firm, medium, medium, soft). Originally, I was afraid that it's going to be too soft. I was so glad I decided to order it! It is soft enough but you are not sinking in it. Love it! My husband loves it too. I sleep in all positions (on my back, sides, and abdomen). Delivery was fast. Packaging was good and secure. Took little bit time to unpack it, but no problems with it. It comes with free sheets, pillows, and mattress cover. No smell, no defects. Easy to put layers together. Thank you, SleepEZ!
My boyfriend bought this mattress last year because I complaining of having back pains. I have not had any back pains since sleeping on this mattress. I just purchased my house and the minute I got my keys, I called and ordered another of the same mattress for my new home. Now we have the same mattress is both our houses. I would buy this mattress for my guest room but I am afraid they will nit want to leave. Thanks Sleepez Am really sleepin E Z Z Z Z!! (Sleeping easy)
Haven’t slept this well in years. Forgot what sleeping well felt like
So far I like it
Excellent customer service! We called during a sale and got a recorded message saying that they would call us back if we left our number and a brief message and they called back promptly and were extremely knowledgeable and friendly. Then when we called in our actual order, the customer service representative couldn't have been any more pleasant (I'm sorry, I can't remember her name!) and was very helpful with some more questions that we thought of. First rate outfit all the way, would definitely do business with them again!
The mattress is very comfortable. I also like the ability to change the layers to adjust firmness.
A very comfortable mattress. Very professional and knowledgeable sales personnel. With the split mattress it is very easy to set up different firmness levels for his and her sides.
Our previous mattress was a Simmons Beauty Rest with pillowtop. What started out as a mattress we liked, became a mattress we loathed. Lots of sleepless nights and pain in the morning. Our online hunt began for the perfect replacement. I first started reviewing memory foam but after a lot of research, I decided against it. I am so glad I did my homework. My search brought me to an unbiased reviews site sleeplikethedead.com. I discovered latex was the way to go for me. I compared several mattress stores recommended on the site and really liked what Sleep EZ had to offer. The purchase was seamless. I received a phonecall after I submitted my online order and was even more impressed with their customer service. All of my questions were answered and then some. My mattress arrived about 5 days after ordering. Assembly was a breeze. I was expecting to have an adjustment period but I instead the pain I was experiencing with my old mattress immediately went away. I sleep cool and comfortable every night. Don't hesitate to make the switch and go with Sleep EZ! They are incredible!
Today is day #25. So far, so good. I'm almost 100% sure that we won't sent it back, even if we decide it's not for us. You see, the worst of this mattress is far superior to the old Sleep Number we got rid of! Seriously, I expected to like it, but my husband likes it too. The jury is still out on whether I'll swap the soft top layer for a medium one, but probably not.
I have artificial hips, shoulders, and one knee. The bed is so nice and soft and there are no pressure points. Best nights sleep I have every had
hips don’t hurt
Great (incredibly great) customer service. Product arrived on time and as expected. Was easy to assemble. Boxes were even labeled. Only room for improvement that I could find was exploring use of a perforated plastic or adding a pull tab assist in opening the foam wraps. Either way, would certainly order again and already recommend to friends. Thanks.
My husband and I have had a sleep ez for 8 years and love it. We bought one for each of our children. The only problem is we are so spoiled it is hard to spend the night anywhere else but home.
We purchased an organic all-Talalay mattress based on our extensive online research. Our mattress arrived timely. It's easy to set up, comfortable beyond words, and has helped alleviate my partner's chronic back pain. Buy with confidence from this company; you won't regret it!
After 3 months my whife and I adjusted well to this mattress configuration. The support is excellent because the mattress normalize the body density and weight distribution in such a way that it countours the body profile in both side and back position; thus eliminating pressure points and spinal misalignment. The key is to align the neck during sleep patterns and the pillow supplied does just that. Other nicities include the adjustable bed that accomodate snore and other luxerious positioning. I'm well pleased with this design. Thx Langsy
Very pleased with my mattresses. And very, very pleased with the company. Easy to get a hold of real people there. Very helpful with all my questions. And went beyond the status quo to make sure I was satisfied. Thanks!
With our old mattress both my wife and I would both wake up a little stiff most mornings. With our new mattress that is no longer the case! We've been sleeping on it for about a month now. We customized each side, with one having a soft top layer and one medium. We experimented with switching sides and found out that the customization was definitely worth it because we both slept better on the side we thought would be the best firmness for our sleep position. We're well pleased with our purchase!
This is our second latex bed. We bought the king size to replace a queen bed. We will never go back to a traditional mattress. It is a little more work to put a king size mattress together due to the size, but worth it. Great communication from Sleep EZ regarding shipping. Thank you!
Bought this for the holidays. Had many very sensitive family members coming who can not tolerate non-organic mattresses. It was so well received that I may eventually move the mattress to the master bedroom!! Was very quick to receive. Arrived in pristine condition. Needs two to put it together, but its easy with four hands. So satisfied!!
We absolutely love our new mattress. We love the split side option! My husband and I needed different firmness levels and this was the perfect way to do it. The layer exchange process was smooth.
Great experience from ordering, delivery, set up instructions and phone support. Would not hesitate to recommend sleepez to anyone looking for a quality latex mattress for fair price
I have rheumatoid arthritis . Husband has lumbar DJD. it is the best bed ever! I have no pain. Husband's 90% better. It's on a adjustable base. GET IT!
So we were very skeptical to buy the first one. We lived in texas the showroom was in Phoenix we couldn't see it and we were hesitant to buy something we couldnt see or feel. Our son had allergies badly and all my research showed these didn't have that kinda problem and didn't off gas and other things. So we bought hte first one for his benefit. Its like a mattress from a 5 star hotel. We bought this config in case your wondering - Xfirm, Firm, and Medium. We liked it so much we changed our king bed as well to the same thing - those two are now 3 years old, we just bought another bed to replace our last remaining regular mattress. The only complaint if I had one is that there is a little bit of compression over three years where we mostly lay. Not super noticiable or anything but something, for that reason we rotate it (not flip) every 8-12 months. But other then that its PERFECT! we have a hard time sleeping on any other beds now!
My wife and I are sleeping longer and more sound than we have in a long time! Great innovation to be able to set up the firmness level of each side of the bed. We're both happy with what we chose!
I am chemically sensitive (but not allergic to latex). This was the perfect fit for me. Staff also very helpful.
Relieved a lot of back issues.. I’m very happy with my ourchase
We purchased 2 mattresses for a folding platform frame to use for guests. They are as comfortable as the 3 layer mattresses we purchased from SleepEZ 8 years ago. They are so comfortable that we wouldn't consider any other brand. The best thing is that you can move the mattress easily, because it comes in layers. I stacked the 2 new mattresses on top of an existing SleepEZ bed, and now our guests can sleep in a regular bed.
I love it 😍
Really, happy with my new mattress. Custermer service before the sale was excellent.
Setup was a little daunting at first because I’ve never built a bed, but it actually was quite easy! Very comfortable beds and very quiet when moving around on them. Great support from the team at EZ... I recommend the EZ bases and they also went together easy without tools!
I am chemically sensitive and have finally found a bed that has no toxic smell. I am quite happy and comfortable in my natural latex bed. The phone associates were friendly and so helpful. One slip up with an item not received was quickly remedied. So very satisfied with my bed and this company!
