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.
The most comfortable mattress I have ever owned. I also recommend getting a latex pillow.View More Reviews
My wife and I are very happy with our new Spindle Natural Latex Mattress. We have been sleeping on it for over two months and it has lived up to its promises. Set up of the mattress was quite easy once all the layers were unwrapped and the cover was laid out on the foundation. I assembled our King size bed by myself in less than 30 minutes - and I am not a big guy. The mattress is stable and very supportive. There is very little motion transfer when one of us gets in or out of the bed. The edges of the mattress are firm enough and we don’t seem to leave any imprint after a full night’s sleep. And as advertised, the bed does not get overly warm during the night. Overall, we are very satisfied!
We bought this bed for my 4 year old and everynight I lie in bed with him and want to stay all night!! He loves it too ;)
I am so happy with my purchase of the Spindle mattress. I searched and searched and having a more natural, nontoxic mattress was important. I tried 2 other brand mattreses, one hybrid spring/latex mattress that was just tol hard and felt it pushed upqard and one all latex organic mattress that was clmfterble but the stitching were horrible and had the worst smell. Then I read about Spindle and just lived the idea of having a zipper and then having tje option of adjusting the comfort layer. I interacted with Neal both via phone and e-mail and he was always super nice and answered my queatione (that were many) and gave me lots of information. I was a bit cincerned about the smell of latex since I had a bad experience with one company but felt it was worth the risk. Having a latex foam that is poured in USA also appealed to me rather than having a latex foam that is poured in Sri Lanka for example and then shipped to the USA. Receiving the covers and the latex layers, I found it easy to put together the mattresses we got one XL twin in firm and one XL twin in medium (to put together as one king) My husband and I both liked the firm and I ended up ordering one extra layer firm. I think my husband will qant to have the extra firm but we are holding of for now. I love the mattresses. The smell is actually nice, like a sweet smell. The feel is great. The cover is also so soft and zipper is of good quality. I could not be happier with Soindle. I highly recomend their mattresses. I also want to mention that the mattresses fits perfect nezt to each other where there is almost unnoticible that it is 2 twin XL and not a king. I thought to put a 1” topper on it but we might not. However we do have a waterproof cover from naturepedic over it, it is not thick but maybe helps a little bit. Thank you to Spindle, I sleep so good, a very supportive mattress for my back. I am 5’4”, weigh 120lbs.
Excellent Mattress. First time that we have ever slept on a Natural Latex Mattress. Great Company. The main reason I purchased from Spindle Mattress is the fact the when you call them you actually are connected to a Live Person not a voicemail system. Also the fact they are 4th generation Mattress Company. Again let me emphasis the importance of answering a call. Something that has been forgotten in Business. We were so impressed we purchased another mattress within 3 weeks.
We are very satisfied with the mattress. We are sleeping very well, on the mattress and not in the mattress. We received it promptly and it was fun putting it together. We added a monster frame to raise it off the floor a little more. My wife was interested in a Temperpedic mattress and I was able to convince her to get one made of natural rubber. We are both happy we bought the Spindle.
No lie, I actually look forward to going to bed. Best purchase ever!!!
Love my spindle mattress. It's incredibly comfortable and very cool. Perfect mattress. Best one I've ever owned. I also own a Casper and I used to recommend casper to friends, but now that I've tried Spindle's mattress, it's all I can recommend. Much more comfortable, the Spindle provides support in all the right areas and like I said before, does not get hot! Absolutely love it.
I don't "feel" the mattress under me, when I sleep.
best mattress I have had so far.
Great mattress giving great nights sleep. Much better feel compared to memory foam. No 'wrap around' feel which makes it harder to roll over.
We are super happy with our Spindle mattress. We are now lifelong customers!!!! Thank you for a superior product and service.
Highest quality mattress you will find. A bargain at twice the price.
We purchased two mattresses, one for our son and one for ourselves, and we all really like them. The customer service is excellent --- we needed help determining whether a mattress would fit in a bedframe and had some questions after we received the mattress, and Kim and others at Spindle took care of everything with patience and good humor.
It was easy to put together and was comfortable from day one. Natural latex is the best option for me and anyone who wants a good night sleep. Glad I made the decision to give it a try.
I spent 17 years on a box spring bed and 10 years on a water bed followed by 2-3 years on a futon then 20 years on a Select Comfort air bed. NOW, about 1 month on a natural latex bed which I have found to be close to a perfect sleeping experience from day one. AS in the story "GOLDILOCKS AND THE THREE BEARS" this bed is: 1. Not to soft; 2.not to hard; 3.ZZZZZZZZ.
Absolutely love the new mattresses! I was a little hesitant ordering 2 without having any experience sleeping on a latex mattress before, but I sure am glad that I trusted other reviewers and went with my spindle purchase! It is the best feeling knowing that my family is sleeping on a truly non-toxic mattress that is also super comfortable!
Fantastic customer service and product. All questions were answered in detail. Very informative and a great company to work with!
I've had a Tempur-pedic brand memory foam mattress, and a store-bought latex foam mattress, but this Spindle mattress is the best mattress I've ever had. Highly recommended.
Love this mattress, and we are picky! Quick delivery. Easier to put together than we thought. We are sleeping very well. Would absolutely get it again.
Amazing. I’d never tried latex before so was a bit worried but all the research I did suggested it was a good option. It’s easily the best mattress I’ve ever slept on. Will never go back to a regular mattress. Also I’m 6’1”, 195 lbs and I typically like a firmer mattress but found the medium spindle to be perfect. Much firmer I think would be too firm.
I decided the firm mattress was what was most similar to our other latex mattress. After two weeks of use it turned out to be a bit to firm so I ordered the topper with cover in a medium firmness. The comfort adjustment was perfect. Now resting comfortably. The topper came in the cover, was easy to get out of box, lift onto existing mattress and provided a little extra height which was nice additive. Love the Spindle product and highly recommend it for quality sleep at a very reasonable price.
I did a lot of research and ultimately chose Spindle. I liked the idea of adjustability and their use of clean and natural ingredients. I purchased the base, too, and was quite pleased at how simply and solidly it went together. I was able to set-up the mattress sections by myself, too, with the aid of the video. The comfort and support of the mattress has been everything I could have hoped for. I wish I had made this purchase years earlier! Thank you, Spindle! Great product!
I like the Latex mattress very much. It distrubutes the weight of my body very evenly. I am comfortable enough but still I feel I want a softer, more plush feeling. I plan on buying two (2) more from Spindle but I want to buy the right comfort level. I will not know unless I try the softer level. I plan on sleeping on this mattress for awhile longer to adjust to it for a longer time to be sure on this end before I make a final decision. I heghly recommend your Latex mattress and your service. Kim counciled me and was very knowledgable of the produc, informative to met and has very good people skills.
It’s very comfortable we are very pleased thank you
perfect choice for us - medium firm
She said, "I never imagined a mattress could be so comfortable". I said, "When I get up, I'll take the cartons to the junk room. We're not sending this thing back".
We LOVE our new mattress!
I LOVE MY NEW SPINDLE MATTRESS! I did extensive research but it was a bit scary purchasing without trying it first. Kim, at Spindle, was so helpful - he answered all of my questions and educated me on various aspects of latex mattresses. I highly recommend this company for the quality of their product and for the care they give their customers.
This mattress is wonderful. I have not felt this good in years. The service was perfect received it very quickly. I am very happy to be able to afford a latex mattress thanks to Spindle. Bought Spindle base with mattress and my daughter and I put the bed together in a snap. I very big Thank You to Spindle.
no breaking in period just a great sleep
I needed a new mattress, and after much online research, purchased a mattress and foundation from Spindle. The foundation was difficult to assemble as the alignment of some of the holes and pegs was slightly off. I managed to get it securely put together, but it wasn’t easy. (If you buy a foundation, be aware that the slats have a white strip connecting them down the center—don’t cut that when unpacking!) The mattress assembly was much easier than I expected, and didn’t take me long at all. I watched the assembly video on Spindle’s website, but I also found it helpful to fold the sides of the mattress cover down over the foundation so I could better align the layers. When I felt the latex in the cover, I was a little concerned the (medium) mattress might be too soft, but once it was zipped up it was fine. I appreciate that I can rearrange the layers if I ever want to firm up. As for smell, the latex had a very mild, pleasant scent which is unnoticeable once zipped in the cover. The foundation and mattress covers both had a relatively strong (clean!) sheep smell from the wool. I shook both of these outside and laid them out in a spare room to air out overnight. I only noticed the scent once or twice afterwards. It was very much a natural smell—there were absolutely no chemical odors. The mattress was comfortable from the first, but it still took about a week to really adjust to it. Since then it’s been great. Overall I’m very pleased with the mattress and foundation. I would buy from Spindle again, and I would recommend them to others looking for a natural latex mattress.
I bought and put together the box spring, but I think it needs to be put on a frame. It is low to the floor and doesn't have back board or front board, if you know what I am talking about. It has taken me a while to get use to it because it doesn't have the spring that I'm use to when I sit down on it. It is definitely different than a bed.
Awesome natural mattress, no VOC smell. Supportive in Medium Firmness, could have even been a bit softer for my tastes. Sleeps cool. With 2 people, assembly not difficult.
A bit harder than I'd hoped for. Seems like good quality. Have had it for about 2 months.
Natural Latex Medium Spindler Mattress; not as great as I hoped for, and not as bad as I feared...Best part, not sleeping on a Chinese toxic chemical waste dump....
I have had this mattress for nearly two months now, and am still not sleeping well on it. I bought it based on previous experience with a latex mattress topper - my bed has a regular old firm mattress and a 2" medium/firm latest mattress topper. I thought that going all the way - plus the natural cover - would be even better. I used the firmness selection tool on the website to select my firmness, and ended up with Medium. It came very quickly, and with three people it was easier to put together than I thought. However, it is far far stiffer / firmer than expected. I sleep on a mix of my side and stomach and it makes my arms fall asleep sometimes. I wrote an email to Spindle about the firmness, and the owner replied with a "stock" email about how it takes time tibfet used to, etc. This email was not helpful. I have now slept on it for nearly two months, and went back to sleeping on my old mattress configuration and slept MUCH better - solidb uninterrupted nights of sleep. So, I am still dissatisfied with the mattress. I am most dissatisfied with the web sector tool, which does not seem well-calibrated -- for example, it asks for BMI in fairly wide ranges, and I think these should be narrowed to make sure lighter people get the right thing. Also I think the tool should come with more caveats or descriptions of the mattress for people who sleep different ways. In my case, an even mix of side- and stomach-sleepin weighing less than 130 lbs, the Soft would undoubtedly be the way to go. I was also frustrated with Spindle's
