With customer data, it is easier to understand if a mattress will work for you. That said, it isn't always easy to stay focused through all the noise from other brands. Customers report feeling both positively and negatively about these mattresses. Some are cozy in their new mattress, but others have complaints about the feel.
A supportive mattress is essential for waking up refreshed in the morning. These mattresses are above average in supportiveness across all sleepers. This is important if you don't have a supportive sleeping surface right now. Most reviewers report that these mattresses are supportive overall.
Edge support is the amount of supportiveness there is on the edges against the center section of the mattress. Reviewers describe these mattresses as having good edge support overall, but some customers may notice more contouring along the sides of the mattress.
Bowling Ball & Density Tests
The bowling ball test is perfect for those that want to measure mattress firmness. It is also a great test to see if there is evenness in support or if there are peaks and valleys. Overall, these mattresses should work with your body and offer an even support feel.
Durability stems from good materials, craftsmanship, and quality control. Companies that don't focus on these things may have issues for some sleepers. Unfortunately, these mattresses get mixed reviews from customers on durability. Some report a happy night sleep, but others have had problems over a short horizon. Make sure to take a look at the reviews before buying.
Understanding how customers feel about mattresses can be a great guiding force for shoppers. Customers, unfortunately, don't always enjoy these mattresses. Some are happy with the feel and comfort of their mattress, but others complain about how it feels for them. If you are contemplating ordering, see below for more specifics that may be helpful.
These mattresses are above average in their supportiveness, which is ideal for those that are suffering from a sagging mattress right now. However, there are some reviewers that describe a lack of support for their bodies, so take a look at some of the other reports from customers to make sure your choice is right for your body.
Edge support is the amount of resistance there is for sleepers along the side of the mattress. These mattresses offer good supportiveness for most, but heavier folks may experience less than ideal edge support.
Mattresses with lasting comfort are amazing, but not always easy to find. These mattresses, specifically, are not rated highly by sleepers for their longevity. This means that some mattresses still may last years and years, while other customers may have much faster discomfort. If you are a bigger person, make sure to take a look at all of your options.
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.
Unfortunately we have returned it due to both sides sinking Leaving a huge hump in the middleView More Reviews
This bed was delivered by two men from 'manna delivery' services, they did a good job and took away all of the boxing and giant bags. It is a little taller than i thought but its not too tall for my sheets which is good. It feels a lot different than my old memory foam bed and when I called they explained what latex foam was and really opened my eyes. My back pain has gone away and also i sleep better throughout the night. i would buy this bed again
Tried to like this matress but it's just a poor product. Weak sides making you feel like you're sliding off edge. Hump formed in middle after a few weeks. Valleys on the sides. Almost impossible to rotate due to lack of handles / straps to hold on to. Even tried to flip it over and all the problems come back on both sides.
We like a firm mattress but this is hard and uncomfortable. Harder than the sliding diagram indicates. My husband and I had back, hip and shoulder pain after the first night. Returning it asap.
After seeing the bed in Costco and feeling how cool the foam was, i was convinced it was a good buy .....but....when foam is covered with fabric, then a protective pad then a sheet the bed was just as hot as my last memory foam bed and after 3 months, it is starting to get indentations in it even though we rotated it several times. I will return it to Costco.
Believe the reviews this mattress is firm! We've had it for about 9 months and still can't get comfortable. The sides have depressions while the middle has a hump. We have rotated the bed as instructed but still does not help. My wife and I aren't big people, and we both have back aches from this mattress. We gave it a try, but unfortunately have not had a good nights sleep. We are going to return it and get something softer.
I have purchased 3 spring Air beds in the past, so did not hesitate to order online. Delivery was very efficient and on time even though I live 175 miles from the nearest Costco. This mattress is very comfortable from day one.
The Latex is great for hot sleepers! This bed does not make me sweat like memory foam or any of pillow tops. I never ever feel hot. It is a firmer plush if that makes sense. It will soften up after about 3-4 weeks. I originally bought the Ultra Firm model but I could not take that slab of concrete and had to return it for this one. It is definitely soft on the sides and firm in the middle. If I were single I'd sleep in the middle to make the bed even. With the firmer middle it is harder to roll over and my wife doesn't try to sneak over to cuddle and steal my heat. I tried 7 other mattress's foam/spring/spring infused latex with foam tops I thought I was going to go crazy, until I found this model. I was desperate for a King size, medium firm, cool bed for $1500ish.
great mattress. firm and had good nights sleep from day one. the delivery service was efficient and courteous. they arrived in the time frame that was give and took away all cartons and papers. would recommend this product .
The consistency of the foam is uneven, hard in middle too soft on sides. Makes you feel like your tilting towards outer edge when laying on back. Seems also to have broke down to a lumpy feel after six months use. Very difficult to change positions as it leaves you feeling like your trying to roll out of a hole. Made my good back hurt. Can't sleep on this mattress any longer, returning.
There was an error in shipping by delivering the wrong foundation, so we had to use our old one, which made the mattress seem soft,but still very comfortable. After using the correct foundation there was a distinct improvement in the firmness,this is the best i have slept in along time especially having physical issues.I recommend you use the right foundation. We are very happy with this, also read the rotating instructions.
Way too soft! You sink right in and it's comfortable at first. But when I wake in the morning I have a terrible lower back ache due to lack of support. I'm a side sleeper and this mattress does not have proper support to keep my spine aligned. This is suppose to be a Latex bed, so I don't know why they add junkie memory foam to the top layer which only makes it hotter and does not breath, completely defeating the advantages of Latex breath-ability and cool sleeping surface.
When I saw this mattress advertised as plush I figured it would be very soft. That is not the case. This mattress is quite firm. It is probably fine for a back sleeper, but I sleep on my side and it's terrible. After the 3rd night I couldn't take any more and put an old memory foam topper on it. As soon as the replacement mattress arrives this one will be heading back to the warehouse.
I was especially interested in getting away from springs and trying the Latex. Unfortuneately, it was a big dissapointment. It seened lifeless, like sleeping on a bag of soft beans. It definitely was not like a cloud. The positive reviews on a similar Spring Aire latex matress are astonishing to me
I have to say, I was a little hesitant on purchasing this after reading the last review but I must say this was one of the best desicions I have made in a long time. This mattress is sooo cushiony and comfortable. For the first time in a long time, my husband and I have actually been sleeping through the night!
We have had this bed for about a month. From the first night, neither my husband or I wake up with sore/stiff backs. We bought our previous bed from Costco and were hesitant thinking we should go to a mattress store. We are so glad we went with this bed. I prefer a softer bed and my husband prefers a firmer bed. While this bed is firmer than I expected, it doesn't effect the sleep we are getting. We also didn't notice a smell. The manufacturer said to let the bed air out but we didn't need to. Hopefully this will continue to be a great bed! We have struggled over the years, trying less expensive options. This is worth every penny.
We were on the hunt for a good mattress, but did not want memory foam. The options are limited. After doing some research we ordered the Spring Air Firm mattress. It was too hard. I contacted Costco.com they arranged for pickup (free) of the other mattress and provided a refund. We then chose this mattress. It is still firm, but not hard. Its supportive and comfortable. Shipping was included in the price from Costco.com, and we had no issues with setting it up. My husband is also very pleased with it.
One word: stone. This bed is soooooo hard and not plush at all. I'm a loyal Costco shopper, but this product is a total fail. It will be going back for sure.
