Grace Zarifa –
I don’t normally leave reviews on anything. But when it comes to deciding a mattress, it’s a long term investment. Your sleep is dependent on whether or not you like the mattress. And it’s a large investment too, opting to get a higher quality one, and one that’s long term, means you’ll spend a lot of money. I spent a lot of time researching and deciding what I was going to get. I read tons of reviews and articles to decide what I was going to get. A Wirecutter article sent me here.
And this was what I landed on. It’s amazing, and perfect for side sleepers. My partner and I are able to get in and out without sinking into the middle. It’s firm enough that I don’t sink into it, but soft enough that I am comfortable when sleeping on my side. After unboxing, I followed the instructions and gave it a day to unfold. It didn’t have a nasty smell, which was one of my primary concerns. I HATE that chemical smell that gets into your sheets and clothes and sticks in the whole room forever.
I am writing this review 3 months later, and I still love the mattress.
I’m a very light sleeper, and super picky with my pillows and my mattress.
If you’re a side sleeper, or light a slightly firmer mattress but one with some give to it, I highly recommend this one!

This mattress was everything I wanted and expected. Was a little nervous the first week because my back was aching a bit but after I read that it takes “up to 2 weeks to totally Inflate”, I understood and haven’t experienced any pain since. I needed a true “very firm” mattress and searched extensively for the right mattress with my older box spring and quality and price. And I must say, Siena did not disappoint. I have degenerative disc disease, 2 herniated discs, and spinal stenosis, so yeah, I don’t play and can’t afford to with my back or I’ll be in nagging constant pain. None of that with this mattress. Thank you Siena!!!!

Bought this 3 weeks ago (Firm model). Just the right combination firmness/support and a sufficient bounce. Excellent edge support. Great sleep. Zero complaints. Was contemplating buying a model that was twice as much and glad I went for this.
One thing though: it is super heavy. I’m sure the fact that I got the king size is a contributing factor. Just sliding it out of the box was a struggle because of the weight. So, if you’re handling it solo like I was, just take steady breaths and take your time. Don’t rush. It’ll get done!

I bought this DOUBLE/FULL sized mattress for a new bunk bed I purchased for my grandson’s visits. It came in a box (too heavy for me alone but with my husband we were able to carry it up the stairs). Once you open the “cryo-vac seal, the mattress grows to full size. I laid on it to test is out and it was VERY COMFORTABLE.
I’ve never purchased a box mattress before, and I certainly can not say how long it would last with everyday use, but I really like this mattress and the price!

Mattress shopping online is a whole thing as those reading reviews would know. I’d never bought a mattress or online or in a box. My last mattress was amazing, but started to wear after 10 years and 3 moves.
I read reviews on Wirecutter, NapLab, Amazon, Wayfair, and consumer reports… to say I was overwhelmed was an understatement and was getting analysis paralysis. I eventually chose to try the Sienn as it seemed to meet the “plush + pillow top + high quality” combo I was after, even though some of the reviews were rough.
I’m SO glad I did. I did sleep on it upside down for two nights and was prepared to return it until I saw that’s someone else had done that, so I checked. I had indeed slept on the boxspring side for the first 2 nights, which is easier to do than one might think. Do not judge! I honestly suspect some of the other negative reviews may have done the same 😂
But this back & side-sleeping idiot is now LOVING it! Very well made and sturdy. Hard to believe this came in a box, then flipped upside down. It’s now amazing. Highly recommend for those who are after plush / pillow tops.
And you firm folks… bless you! I don’t know how y’all do it. Life is too short for hard mattresses

sinks down on one side. the company only wanted pictures of the mattress with a board across the sink in spot. well a memory foam item retains its shape when no one is laying on it!!!!! no help at all BEWARE !!!!

I have no complaints with this item. I needed something quick after a relocation and this served its purpose. I’ve slept fine on it, sheets stay on (which hasn’t always been the case with more expensive mattresses), and the off-gassing was either minimal enough for me not to have noticed or it dissipated quickly.
