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.

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.
My wife and I live this bed so much. When we don’t sleep at home we miss it. Very sound sleep every nightView More Reviews
Was pleasantly surprised with the support, comfort and overall better sleep provided by this mattress. I had a spring mattress for over 8 years and decided initially to go for a hybrid construction of spring and foam. This hybrid option eventually did not work out and I went with the all foam solution. All my initial worries were gone after that first night, the mattress does provide a good level of support and dissipates heat quite well. The only down side to this mattress was the smell it had for about a week after unpacking it, not a terrible thing to have to deal with for some days but not pleasant either. Regardless, I would highly recommend this mattress.
I bought the queen size mattress. It was delivered promptly and weighed 74 pounds. It wasn’t too hard to move around or dump out of the box (I have a low platform bed frame). Did a little adjusting of the cover or it would have opened lopsided. It is wonderful. It is supportive. There are no pressure points to cause pain anywhere on my body. I sleep with less tossing and turning so I’m more rested in the morning. I love my Leesa. Best $800 I have ever spent.
My Leesa is amazing. My back feels so good when I wake up in the morning (not always the case on other mattresses). I love memory foam but hate how hot it makes me feel and Leesa seems to have solved this problem. It reminds me of memory foam but I never overheat. And I don’t notice my wife getting out of bed in the morning. I paid a lot more for a Sleep Number and am replacing it with my Leesa!
Love this mattress! Firmness is perfect! I researched for a year and glad I chose the Leesa.
Going to bed has become one of my favorite times of day as a result of the Leesa mattress! Nicest bed I've had the pleasure of sleeping on!
I love the two Leesa Mattresses that I just bought. I now slumber in a deeper sleep. I don't wake up during the night tossing and turning, and look forward to going to bed! The pillows are fantastic. .
I love it. The best night sleep with out waking up stiff. It is very relaxing
We love our mattress! You sink in at all the right pressure points. We both especially like how our hips are sinking in just enough. It’s not slow to form like other memory foam beds, so when you roll over, your not leaving a hole and sitting on top. Our only complaint and the reason I didn’t give 5 stars, is the smell. During the first 2 weeks, it was pretty strong, it’s been about 2 months and it’s finally gone away for the most part. I’ll occasionally still smell it. I imagine all foam beds have this smell.
This is a very firm mattress. I wish there had been an option to choose a softer one. Also, deep-pocket sheets, which most new sheets are, do not fit well. They are much too big.
My whole experience with Leesa has been wonderful. I ordered the mattress and foundation and had the mattress two days later! The foundation takes a little longer but I had that within a week. There was very little off-gassing and I didn't find the smell offensive. I'm very sensitive to smells/fumes, I have asthma, but we were able to sleep on this bed the very first night. The mattress is THE most comfortable thing I have ever felt! It somehow manages to cradle you, like a big, soft marshmallow and provide the perfect amount of support. I suffer from multiple sclerosis and fibromyalgia and this bed has made such a huge difference in my life. I no longer wake up feeling like I've been beaten-up and while I rarely sleep through the night due to my illnesses, the rest and sleep I get on my Leesa has greatly improved my life. I've honestly never experienced this level of comfort! Thank you, Leesa!!!
totally awesome comfort after 6 weeks. Love it.
Best night sleep that I have had in a long time. The only downfall on this mattress is I never want to get out of bed!
I don't know why we waited so long
My wife and I LOVE our mattress. But that begs the question, how do you know you love it? First of all we aren't complaining about how we feel when we wake up anymore. We don't talk about buying a new mattress or even considering making a change. We fall asleep, and stay asleep (except when our 5 mo old wakes us). It's become a wonderful part of our evening, most nights I look forward to lying down! Great mattress for the price.
relieved that it's as good as the reviewers make it out to be and relieved that i turn much less than I did on a spring mattress. My wife's experience is the same. It's a deal.
We bought a king size Leesa for our master bedroom and loved it so much we bought a queen size for our guest bedroom. Our guests are going to love it!
I have to admit I was a bit skeptical that a mattress that is not super thick could be comfortable. My husband and I were both pleasantly surprised. The mattress has been wonderful. Not too soft, not too firm. It is well made with a beautiful cover. Love my new mattress
Best mattress yet
nice to finally get a good nights sleep.
Fell in love on the first night and have slept better since. It is the right amount of firm and soft and cannot tell when my husband moves next to me. I am a Leesa owner for life!
I am enjoying this mattress
I enjoy my mattress and will buy again in the future. Bed feels firm but contours to my back. It has lessened my lower back pain. Only gripe is that the mattress has a plastic smell upon opening that lingers. Had to leave windows open for a week to let it air out. Smell is still there but faint.
I love the matress and sleep great. It provides great support and breathes well. It still has a slight chemical smell from then it was made I guess but you get used to it.
Only reason I don’t give 5 stars is, LEESA tell us there may be some “off gassing” from the mattress for a few days. That means fumes emit from the mattress’s man-made material, a kind of settling process.
In the case of my mattress, it was like sleeping over an open can of paint for over a month. Then the “gassing” finally stopped.
I sleep really well on this mattress. Glad I bought it.
I'm a stomach sleeper and this mattress was too soft for me. I needed a mattress that was a bit more firm.
Our mattress has already developed troughs. It's still comfortable enough but there's no way it will last even 3-5 years, let alone the 10 a mattress at this price point should last.
We bought the leesa for our Special Needs son. He is 35 and has a hard time sleeping. He has loved it. Sleeps so much better and is in a lot less pain when he gets up. Thank you.
My husband just had back surgery and he has been loving the Leesa mattress. We both think it's wonderfully supportive and just the right amount of soft. We love it!!
Delivery and packaging was quick and easy. The light smell it had only lasted a day or two. As a heavier set guy, it felt amazing. It was super quiet, unlike a spring mattress. Very little disturbance with my wife. My wife on the other hand, hated the mattress. She's considered petite, and the more dense nature of foam mattresses meant she felt the Leesa to be a lot more firm than our last mattress. Sadly, I ended up returning it for her. It's a great option for medium to large folks. By the way, the return process was a breeze and refund processed about 5 days after the pickup. Amazing service.
My fiance and I are about a year into our Leesa experience and for both of us, it's been the greatest investment. She and I both travel extensively and we sleep in a lot of hotels but no matter how much we enjoy the mattress, we always look forward to coming home to the Leesa.
Super soft and well made mattress! We have been impressed with the quality and how it’s almost impossible to have a bad night’s sleep on it. It does run a little hot but I’d imagine not as hot as other memory foam mattresses due to the Leesa’s thoughtful construction.
I have gotten the best sleep ever! I’m a back and side sleeper and it’s been amazing for me! Definitely worth the investment! If you’re going to buy a mattress that will last and will allow you a great sleep, go with LEESA!!!
comfortable and supports my back well while being comfortable
Bought this mattress for our son, he is a very big boy, hoping the mattress won't start sagging in hot e middle as every other mattress we have bought for him! We will see!
I've been having difficulty sleeping due to a injury. I purchased the Leesa mattress and was finally able to get a decent night sleep.
After sleeping on this mattress for over a month, I’m ready to review it. This is by far the most comfortable mattress I’ve slept on. I also upgraded from my queen mattress to a king, which has been excellent. Along with the great sleep I’m having throughout the night, I’ve noticed I no longer wake up when my husband adjusts or gets in and out of bed. Experience with this mattress has been great!
For me, the Leesa Mattress has proven to be a wonderful mattress. I have bursitis in both hips; I have had zero hip pain with this mattress. I sleep soundly, comfortably. If my kids hop into bed with me, they can move without disturbing me, and vice versa.
I highly recommend trying this mattress. What price would you put on a peaceful night's sleep?
