  • I Fall Asleep Faster
Size: Queen
I got the Siena Queen Mattress because it came down to affordability. I was skeptical if this mattress was the right one for me, especially after watching YouTube videos and reviews. It's only been one week, but so far, I like this mattress. I fall asleep a lot quicker than I did in my previous Twin sized Tuft and Needle original mattress. Pro's 1. I sleep sounder in the Siena. 2. I noticed I don't toss and turn as much at night 3. The Siena mattress feels like it conforms to my body much better than my previous mattress. 4. Many Online reviews rated this mattress as a 6.5 in firmness. I would have to say maybe it's even a 6. It's definitely a medium firm. I don't feel like I lay on the mattress, but I don't feel like I'm sinking in it either. For me, it's the perfect amount of support and plushness 5. I built the bedframe and put the mattress to lay on it at night and went to sleep on it 3.5hrs afterward and still had a good night's rest, and the mattress continued to get firmer the next day. This is really convenient if you don't have a space to let the mattress get firmer for the 24-72hrs post opening in it. 6. Very comfortable mattress for side and back sleepers. Overall: After sleeping on it for a week, I am happy with my purchase and I'm really enjoying this mattress. Cons 1. If you're a hot sleeper, you will continue to feel hot. It's better than my old mattress. I would have to say. I used to wake up in the middle of the night from how hot I would feel. But now, with the Siena, I still sleep hot but I'm not waking up in the middle of the night. I just wake up sweaty. Again it's only been a week, I will try to remember and update this review after a few months of using this mattress. ... show more

  • Hmmm
Size: Full
Not what I expected. It was not as sturdy as I expected, I never owned a bed like this so I didn’t know what to expect, and it felt like I was on an air mattress. It was easy to set up, no problem at all. I was able to do it alone. It didn’t have any smell, as I had read in some reviews. It fully expanded within the first 24 hours, but I allowed it more time, as I didn’t want to rush it. It was not heavy at all, less heaven than my traditional mattress. I was quite disappointed in the lack of support, but now I understand more about memory/foam mattresses, and a lot has to do with the layers of foam, and this one only has 5.5. I did try to return it, as Amazon suggested and UPS, refused to accept, and I was stuck with an extra mattress. The wonderful Nicole from South Africa department helped me, and came up with the great idea to donate it! So that’s what is happening with it! Thank you Amazon for being so accommodating. I’m sure someone who has less back problems, would enjoy the softness, and comfort, of not having coils/springs, and how soft it is, if they weigh less than I did. But I’m plagued with too many back issues. Sadly I just couldn’t make it work. ... show more

  • Best mattress i have owned
Size: Queen
I was skeptical as to if purchasing a mattress at this price would turn out to be a bad decision. Now it has been a few months and the mattress is still firm and comfortable. I added a pillow topper to do it increase the softness and my body just melts into it while still having the firm support my back needs. I would definitely recommend. ... show more

  • My favorite in our home
Size: King
I purchased this for my sons room. I have a Casper myself and we have a Nectar in our guest room and I purchased this for my sons room. It’s kind of fun comparing all 3. For me I like the firmness of this mattress best of all 3 of them. It is also lighter than the other two so easy to make the bed. It’s easy to move if needed. I definitely can not say that about the Casper. I definitely recommend this mattress and wish I had one in my room now as well! ... show more

  • I did not sleep like an exhausted bear.
Size: Twin
This mattress looked nice and felt nice when touched at first but within four hours I was in pain.The value for the money would have been nice if I could actually sleep on it but I couldn't. Felt more like firm to me instead of medium or medium firm. I was easy to open and unroll. .
