Purchased this mattress for my 7 year old who needed a new mattress and she says it is so comfortable she is sleeping much better at night and not saying her mattress is hard. Once I unpackaged the mattress it took about 3 hrs for the mattress to come to its full size thickness. I ordered In a size twin XL and the size is very true.

We ordered the twin 8 inch mattress for our child, and it has been great for them. They say it is extremely comfortable, and I find it comfortable as well when putting them to bed at night. I was pleasantly surprised that it offered enough support for 2 people with combined weight of 250lbs despite being only 8 inches and costing so little. I guess that just shows how nice the quality is! I definitely think it's a great value given how affordable it is. There was no stinky off-gassing period when we opened it, and it was ready to use in just a few hours (3-5, according the instructions) so my little one was able to sleep on it the same day it arrived, not having to wait a full 24 hours like some other mattresses. It's been so great that we are planning to order another Siena for our guest room! Definitely recommend.

This mattress is nice overall. I can definitely understand why some would think it’s too firm, but I find it rather comfortable. It definitely forms to your body and has ample support. Ended up raising to just shy of 8 inches. I will say that after only having it a week or so I noticed that the gray cover had some spots where the threads were running and creating small holes. I also have to comment on the smell. It has taken literally two months for me to not notice the smell consistently anymore. I aired it out for 24 hours initially and then proceeded to unmake the bed and air it out for over another weeks time, and I could STILL smell it. Despite having all of the windows open and the ceiling fan on high every day for 10 hours. But I am happy with the comfort, and I did not find the price to be unreasonable.

Great. Filled up within first hour. Filled to correct thickness of 8”. Firm, but not excessive. No odor detected. Have not actually tried sleeping on yet, but sat on and felt good. Would order again.

🧱 as can beReviewed in the United States on January 30, 2025

Waited 24 hours after opening to use it and it is definitely firm. It certainly took some getting used to it coming from a very very soft memory foam that was hurting my back and impossible to side sleep or stomach sleep. Didn't really like it at first, it was like sleeping on the floor. But after about a week of sleeping on it, it got ALOT comfier as I broke it in. I couldn't live without it now and sleep much better with ALOT less back pain. Finally able to sleep in any position I want. Look no further. This is a GREAT value.

Comfortable and supportive without being too firm or too soft. I’m really grateful I found this mattress. Super affordable, easy shipping and easy to unbox. Already purchased a second one for my son.

I ordered the twin 8" mattress and it's honestly great, I just made the mistake of reading medium, not medium- FIRM so that's my mistake. I gave it one night but it is too firm for me personally as a stomach and side sleeper so I'll just have to get a topper but that is again, my own fault. The mattress itself is great, came packaged beautifully, was easy to roll out and puffed up to size almost immediately. Would definitely recommend the 8" for any back sleepers that prefer a more firm mattress
