Review: Solid choice that didn't break the bank - I bought the Tuft & Needle Kin 10” memory foam mattress after a cross-state move when I needed something affordable and comfortable. My partner prefers a firmer memory foam mattress, while I’m used to a softer, plush pillow-top, so finding something that worked for both of us was important. At first, I was worried it might be too firm for me, but after about two months it softened and now feels just right for both of us. It provides enough support for him while still feeling comfortable for me. We found Tuft & Needle after staying in a friend’s guest room that had their original hybrid mattress. The Kin isn’t quite the same feel, but it’s a good alternative at a lower price point. I also appreciate that the materials used are clean and natural. Overall, it’s been a solid mattress that didn’t break the bank and has worked well for our first apartment together.
Review: Weirdly comfortable - It's admittedly a bit early to review this mattress, having only slept on it for a week now. But I wanted to share my thoughts since I had initially purchased a Modway and returned it to get this mattress. First, I'll say this - desertcart tells you to give this up to 72 hours to fill up, so I actually called customer service to ask whether you really needed to wait that long. The answer is no - the mattress can fill out in as little as 2 hours (mine sure did), and even if it doesn't fill all the way right away, it doesn't hurt it if you sleep on it. So said the folks at Tuft & Needle. Second... This mattress does not immediately feel like the most comfortable thing in the world. The Modway I'd just returned was a memory foam mattress with a cooling gel pad, and when you got into it, it immediately felt super comfy. I could lay on my side and my back and both ways felt phenomenal. But when my wife slept on it, she sank WAY down. And she'd wake up with terrible back pain. So when I set up my new Nod mattress...and tested it out...it felt strangely rubbery. It didn't feel immediately soft OR firm (they say medium, and I suppose that's pretty much what it is). It also doesn't let you sink in - at all. With the memory foam mattress (Modway) I barely felt my wife moving on the other side. With this one, I do kind of feel it - but not as much as you would with an innerspring mattress. Laying on the mattress, again, it doesn't immediately feel like the most comfortable thing in the world, but both my wife and I have slept incredibly well on it. I wake up feeling refreshed, rested...and no pain for either of us! I sleep on both my back and my sides, in case you're a side/back sleeper & you're wondering... It also sleeps MUCH cooler than both my former innerspring mattress and the Modway, which supposedly has some sort of a cooling gel layer. With both of those, I woke up uncomfortably hot at least once or twice during the night. With this mattress, no such issue. So...older women rejoice! No more crazy night sweats on this thing. So...that's pretty much my experience so far. Here's a summary: GOOD STUFF: 1. don't feel your partner's movement as much as on an innerspring mattress, but do feel it a bit more than a memory foam mattress. 2. doesn't get hot - at all. No night sweats ladies! 3. wake up feeling refreshed, no aches & pains 4. can use it pretty much right away, within a couple of hours - no need to wait 72 hours NOT SO GOOD STUFF: 1. doesn't "feel" immediately comfy, especially if you're a side sleeper. Not sure how much that matters since my sleep quality has been amazing so far. 2. you do feel a LITTLE bit of your partner's movement on the bed...then again, my wife has not had to adjust as much on this mattress, so what little movement you would feel is reduced. Overall, I highly recommend this mattress so far. I'll update in a few months if anything changes.

## Questions & Answers

**Q: Does this have the certifications like the other t&n matresses (standard 100 by oeko-tex, greenguard gold, certipur-us)?**
A: As an update to your question, the Nod has been certified STANDARD 100—Class 1 by Oeko-Tex as of the end of December 2018. Thank you for your patience as this certification was being processed! —The Tuft & Needle Team

**Q: How does this compare to their "hybrid" model on the T&N website? I see that it's two inches shorter (10" vs 12") but are there any other differences?**
A: Hi there,

Thank you for reaching out with your question. I'll be happy to quickly break down each mattress.

The Nod Hybrid is a 10" thick mattress made with a combination of Tuft & Needle T&N Adaptive® foam, open cell memory foam, and pocket coils. These materials work together to provide the great support of foam mattresses with the more traditional comfort of spring mattresses. The  mattress cover is made with polyester and is designed  to be soft to the touch and breathable without sacrificing durability. It is resistant to pilling and tearing.

The T&N Hybrid is a 12" thick mattress comprised of 6 layers of foam and coils designed by Tuft & Needle. The T&N Hybrid is made of T&N Adaptive® foam but in addition, this mattress's pillow top layer is infused with carbon fiber and graphite to keep it sleeping cool. The additional layers of pocketed coils and foam found in the T&N Hybrid makes it more breathable and slightly softer than the Nod Hybrid. We've also reinforced its edges with firmer springs to add support. Its cover is a polyester knit ticking designed to be soft to the touch, feeling more luxurious and resistant to pilling.

I hope this has helped! If you have any other questions or would like to speak to our team directly, email us at amazon@tn.com. 

Best,
The Tuft & Needle Team

**Q: Does the Nod come with the same return policy as the other mattresses?**
A: The Nod comes with Tuft & Needle's free 100-Night Sleep Trial. This is processed by Amazon, so in light of a return, one would just need to reach out to Amazon's Special Handling Team. Feel free to reach out to us with any further questions or concerns at amazon@tn.com. —The Tuft & Needle Team

**Q: we like an extra firm mattress - is this extra firm or does it sink in as the body lays over it?**
A: I have several back issues -I needed a firm (but not rock hard ) mattress. This mattress has been a God Send ! It’s firm enough for me to sit up and get in/out of but doesn’t put my arm /shoulder to sleep like many extra firms will do. I’ve had for several months -no soft spots or holes to cave into -it’s perfect for me!!

### ⭐⭐⭐⭐⭐ A Pleasant Surprise
*by D***A on November 5, 2020*

I bought this mattress to replace yet another air mattress that I have used for years as a replacement for a waterbed mattress. The air mattresses have been okay, the last one I had was a very expensive three chamber model, but it finally met its end (not a leak). I had seen commercials for the "mattress in a box" offerings, so I was curious if they came in a California King size. Some searching on Amazon lead me to Tuft & Needle. They offered very attractive prices as opposed to others I had seen advertised on television. They also carried a California King in an 8" thickness, that was perfect for my existing frame. So after reading both positive and negative reviews, I took the plunge and ordered. It arrived quickly, and in a box that was smaller than I expected. Unrolling and removal of the plastic protection covers was simple enough for me, but I would suggest two people do it for ease. I did it myself, so it can be done, but two people would make short work of the job and endure far less of a struggle. I experienced no strong chemical aroma that I had read about in some reviews. After a couple of hours I tested it out. The instructions said it was okay to use after two or three hours. My initial response was that of pleasant surprise. It was very comfortable and filled the bed frame exactly as I had hoped. It also allowed me to use my normal bed rails once again as the new mattress did not stick up above the rails. After I got the bedding on, the whole bed appeared much lower to the ground than it did before. That was really because the old air mattress was a good 12" and it had a 4" memory foam topper on top of it. Making it actually taller. This was not a problem. My first night of sleep on the mattress was blissful. So comfortable, dare I add, "soothing"? At first, I was sort of afraid I would sink, the foam compress, and feel the wood underneath. That did not happen. It also does not sleep hot, which was another worry. Yes, like all mattresses, you leave a warm spot, but the mattress dissipates the body heat and allows me a wonderfully comfortable night of rest. All subsequent sleeps have been just as comfortable and pleasurable. I honestly could not be happier with the experience I have had with my Tuft & Needle mattress. The cost was a lot less than I expected to pay for a mattress in a box. I had hesitation that I would get cheaper quality, but that fear was proved wrong. I have received nothing but great sleep and the feeling of a well made purchase. I can only imagine that the thicker versions would be just as, if not more comfortable, but I am completely satisfied with the one I purchased. In my reading, I believe that the "model" I chose is an exclusive to Amazon. They do offer a satisfaction guarantee, but since my satisfaction was met and exceeded, I will not be using it. If you are considering purchasing this mattress, do so with confidence. If for some reason you are not satisfied, use their guarantee. I believe that you will be just as satisfied as I am with this mattress. I would suggest not judging it until it has fully expanded (A couple of days), though I knew I had made the right choice the first night I spent on it. Thank you Tuft & Needle!
