Customers are always on the lookout for highly durable mattresses.

However, even with that being said, these mattresses have some good marks on durability. They should last over 7 years for the average sleeper. If you are heavier or use your mattress more than nightly, then you may expect a little less durability.
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 read and watched multiple reviews and was a little skeptical about if this mattress would be a good fit for me. I decided to give it a try, and am so happy with my decision. I have only been able to sleep on it a few nights, so I can't speak to long term satisfaction, but just the feel of the mattress is so unique and comfortable. Every time I pass by my bed now, I can't help but flop on it and lay there for a few minutes. If you are on the fence about trying the mattress, I would say go for it for sure. The only disadvantage that I've noticed so far is that it is near impossible to get out of bed in the morning. I was a few minutes late to work the last few mornings because I did not want to leave my bed. When I was reading all the reviews, I heard that purple fluffs up their review page to make their mattress look better. After trying this mattress, I do not believe that is true. I believe that people genuinely love the product and want to share it with other people. I am not typically one to go out of my way to write a review, but this product is incredible so I felt compelled to do so. Obviously everyone is different so you may not have the same experience I have had, but if you are on the fence and looking for a great mattress, give Purple a try.View More Reviews
It’s been an OK experience. We had a very old mattress so when our Purple mattress arrived and we tested it out the difference was big. The major good thing is that I don’t feel my husband moving and turning around anymore. That’s great! But other than that I can’t really say it’s an “out of this world, amazing mattress”. We were also disappointed cause we bought it just before thanksgiving and we asked them to check if a Black Friday sale was going to take place. No one could inform us anything so we went ahead and bought it with the current sale. We were very disappointed to find out on Thanksgiving Day that the sale at that time was the free Purple Blanket + $100 discount. We called and they couldn’t honor us that so that was a bummer.
I don't know when we purchased this mattress. I think if I were a back sleeper, it might be good, but I sleep on my side. This mattress does not allow enough give at the hips (contrary to pictures showing the spine in perfect alignment). So, my waist is pulled downward causing discomfort and constant shifting and readjusting. I think I slept better on my 20 year old mattress. I actually hope we can return this mattress and get something else. Would hate to have a mattress that we paid hard earned money for and can't stand to sleep on.
Every morning my wife and I would wake up with back ache's from our old mattress. From asking around my chiropractor said many of his clients had tried the purple mattress and really liked it. We decided to purchase one and it is great. Nice and firm. We sleep much better at night and feel great in the mornings now.
terrible experience bought purple products some showed up, some didn't and purple customer service sucks they don't reply and have been no help what so ever. terrible experience.
We have not noticed a difference in back pain just yet but we do notice we don’t want to get out of bed in the morning due to the mattress being so comfy.
A gift for my pregnant daughter. She says PERFECT!!!
Once I got a few adjustments from my chiropractor and slept on my new purple mattress I haven’t had any back problems since. I’m very satisfied with my results.
I love this mattress. It is now my favorite place to be. So comfy and cool all night long.
I’m a big fan of everything but the bed. I love the pillow, the sheets, the driving cushion. 10/10 for those. The mattress is terrible. No matter which way I sleep I’m always waking up with lower back pain and I never realized it was the mattress until I started sleeping in hotels and waking up pain free. It’s 1000% the mattress :(
I am not going to buy purple products again. I got the mattress which was advertised as being long lasting but after a few months it has obviously gotten worn in. It started to feel like crinkled plastic after less than 3 months and I thought about returning it but got lazy about it. We also got the purple mattress cover but the first time the baby wet the bed it went right through the cover. Mattress cover useless. The bed stand commercial shows sumo wrestlers fighting on the platform, but when mine showed up the holes were drilled in the wrong places by about a 1/4” which made it extremely hard to put together and 6 months later the metal bangs from warping and being pushed around by my weight. I spent a lot on this bed and all the great features advertised were hype and lies.
After hauling this heavy thing up two flights of stairs, my back was killing me. I unpacked the mattress, laid down, and within 5 min, my back was feeling great! I have had the Purple mattress now for more than 2 weeks, and I’ve had wonderful sleep and zero back pain. I need a firm mattress for my lower back, but as I’ve gotten older, a traditional firm mattress hurts my shoulders and hips. The Purple supports my back while it forgives my pointy bits. I love it! Can’t recommend it enough!
I am still deciding I fall asleep well but have been waking up with back pain pretty intense not sure if it’s the mattress or what yet
I'd had my old mattress for 15 years, and knew I needed an upgrade. I compared over a dozen different mattresses before going with Purple - the reason I selected Purple was because of its new and unique technology. I'm so glad I went with it - it's so supportive and comfortable. My partner had trouble adjusting (side sleeper), but after about a week, he is well-adjusted and sleeps like a rock! The only issue I had is that the queen-sized mattress is definitely more than 100 lbs, but on the site, it's advertised as being less than 100. It was *extremely* heavy, and difficult to move once it's out of the case, but its level of comfort and support makes up for it all.
Slightly firm but the softness feels luxurious
Every morning my back is sore. The pain is about 8 of 10. An hour after I am up and moving around the pain disapates. I think I may need to add 200 lbs of weights during the day, to take some of the firmness out of the mattress.
I can’t reqlly say more than this bed is amazing. I have had it for two weeks now and sleep better than I ever had before
This is my second bed with purple and both times I have been more than pleased. I’ve never slept on a more comfortable bed or dealt with better customer service!!
I have multiple back issues including stenosis and bulging discs as well as osteoarthritis. By far the most comfortable bed I have ever slept in. I look forward to going to bed at night. It is now my haven. From couch potato to purple potato :)
I wish that I could write a review on the item that was suppose to be here last week but I haven’t received it yet. When I emailed purple they took almost a week to get back to me with a ****** nonsense answer that they ran out of material and would need another 1-3 weeks to make my mattress then they would have it shipped. I’m 8 months pregnant and sleeping on an air mattress because they ran out of material. Don’t ever buy from this company. You will be waiting months to receive your product with no communication from the actual company!!!
I love the color purple anyway but this mattress has changed my life! The best sleep I have had in 10 years! I'm getting them for the entire house!
...but so far it’s been great. A mattress is a long term relationship though so what really matters is how I feel after a few months. So far I really do love it, but I was sleeping on garbage before. Trust me, I’ll edit this review later if my opinion changes.
I had high expectations.... you’ve exceeded them.
I gifted this to someone, and they gave it the best possible rating !
Within 2 days of sleeping on this bed my neck and back pain was non-exsistent. I could sleep for 5 hours and wake up refreshed. It's been a month now and I am soo happy with my purchase..
I wanted to support a local Utah company and was so excited to receive this mattress but this was a huge mistake. The quality of this mattress felt like a blow-up mattress that should cost a fraction of the price. For me (skinny guy sleeping on his stomach) it was just uncomfortable and felt weird. To be fair I've heard others say they bought it and like it but for me it was laughable to see what I received for $1200. I also bought the purple mattress protector and it feels like plastic compared to my previous one. Be careful because they won't refund the mattress protectors so I wasted about $70. Buyers beware!
I can’t believe how awesome this bed is! I did lots and lots of research and decided to get the Purple bed and I’m so happy I did! I have never slept better! Super happy with the bed!
First off, the king sized mattress does not fit on our king sized bed frame. It hangs off the foot of the bed and the slats show on the sides. Ridiculous. Never had this issue with any other bed. The waffle pattern feel isn't exactly soft and comfy either. Still we gave it a try to see if we got amazing sleep. It wasn't for us. I thought the returns process would be simple like Casper's. I called and the wait was long so they called back. Then instead of processing the return then and there like Casper did, I had to get an email and submit a return form. And then we'll see how the rest of the process goes. Also note that when you buy the mattress there is usually a free promo item. When you return the mattress, you cannot return the item so you are charged full price. There should be a note when you select the promo item to remind customers of this fact. I would have selected no gift. But I guess by being shady, Purple ensures if you hate the mattress, at least they sold you $130 sheets.
Let me start by saying WOW. I have been sleeping on a Nectar mattress for a while. Every morning I would wake up to lower back pain that would go away after 30 minutes. I blamed this on being 51. The first night sleeping on the Purple I woke with no back pain. My wife had back surgery 2 and 1/2 years ago she says this is a game changer. My only regret is not ordering this sooner and not ordering the pillow. PSA the sheets are also amazing.
Hands down the best mattress. If Purple contacted me and said I needed to pay $300 more to keep the mattress I would rather pay it than give it up. The best investment and purchase I’ve ever made. My partner says the same thing!!
I work 2 jobs, about 55 hours a week, and am on my feet 95% of that time. had lots of trouble sleeping thru the night until the Purple mattress came along. in 3 weeks, i have slept amazing. even slept thru my alarm 4 times!
This thing helped me rest on a whole nother level i will definitely buy another one when this one is of age.
Me and my fiancé absolutely love this mattress. We’ve slept so well since we’ve got it.
Loved our Purple mattress so much we decided to allow our guests to experience this great mattress as well.
This mattress is absolutely life changing! I suffered back pain and haven’t slept well in years! The purple mattres has changed my life. I sleep like a baby and have no back pain at all!
I was definitely skeptical about buying a mattress online, but with the return policy I figured I would try it. Best idea ever! I’m such a light sleeper, and I no longer get woken up when my husband is restless or the cats are jumping all around. Plus, it’s so comfortable!
I got the wrong size mattress and while I appreciate their willingness to do an exchange, the process has been liborious. The product itself is quite nice for the price. Thank you.
I’m a prominent side sleeper and was consistently waking up with shoulder and back pain. This new mattress solved those issues the first night I slept on it. I would definitely recommend it to anyone.
Feel like I'm falling out a bed wake up !with a back ache
This mattress is perfect. My wife and I both used to gravitate toward the center of our old mattress, where it caved in, and wind up fighting about which of us was on the other's side more. This isn't a problem anymore! We like sleeping together again! She even hooked up the TV in the bedroom! We're never leaving this bed. Seriously, it's great. It isn't hot. We can't feel each other move at night, which is good for my wife because I move around more than two pigs fighting under a blanket at night and now I get yelled at a lot less on the whole. Money well spent!
