They’re two of thebest cheap mattresses, but how do you know which one is right for you?
To start with, they’re both very different beds.

Allswell is owned by Walmart.
It avoids the expected pitfalls of cheap memory foam, offering a supportive and cool night’s sleep.
However, as the mattresses are so different, we can’t rule the Allswell out completely.

Let’s dive into our Siena vs Allswell mattress showdown.
Beneath that sits four inches of a support foam.
This dense foam features molded ripples, to enhance airflow and improve breathability.
At the base lies four inches of durable foundation foam, providing stability to the upper layers.
The build is similar to the Nectar memory foam mattress from fellow Resident Home brand, Nectar Sleep.
you’re free to see how those two beds compare with ourNectar vs Siena mattressguide.
The design of the Allswell is quite different to the Siena.
As a hybrid mattress, it contains both layers of foam and a spring layer.
These provide cushioning intended to mold to the shape of the body.

When it comes to the Allswell, there are potentially some issues concerning durability.

Neither mattress comes with handles, which does make moving them tricky.
While the Allswell has the more complex design, it isn’t necessarily thebetterdesign.
Our reviewer rated the Siena as 4/5, while giving the Allswell just 3.5/5.

Siena runs an evergreen sale, with a queen mattress typically retailing for $399.
The price rarely changes, so don’t expect it to go any cheaper.
The Allswell, however, is the cheaper choice, with the queen often costing around $317.

When it comes to extras, there is a clear winner: Siena.
Even some of thebest memory foam mattresseshave shorter trials than this.
In addition, each Siena mattress comes with a 10-year warranty.

The Allswell also comes with a 10-year warranty, but the trial period is disappointing.
You get 90 days to make a return, but the mattress must still be in its original packaging.
Not good, if you want to test the feel of the bed.

The Allswell is cheaper, but the lack of trial period is a big no.
The Siena mattress is described as a 6.5, which is medium.
Since our review, Siena has slightly altered the construction of its memory foam mattress.
The middle transition layer is now taller, while the top and base foam layers are both slightly shorter.
Beyond firmness, the construction of the mattresses also contribute to a different feel overall.
As the Allswell is a hybrid, the bulk of the design consists of coils.
This gives the mattress some bounce.
The Siena, on the other hand, is all-foam.
Memory foam mattresses can sleep hot,but this wasn’t a problem for the Siena.
Warm sleepers should get on well with both of these beds.
Both mattresses also performed well at motion isolation, earning 4.5/5 from our reviewer.
Here, the Siena mattress really shone.
The firm foam ensured that every inch of the surface could provide excellent support.
Okay for a guest room, but a problem if you plan on using the mattress every night.
Siena vs Allswell mattress: which should you buy?
The Allswell, in comparison, is just a 7/10.
You’ll have time to decide if the Siena is right for you, before you commit fully.
And while this model rarely goes on offer, it’ll still likely be the cheaper of the two.
