A big price tag doesn’t always equal big comfort, as the Siena Memory Foam Mattress proved to us when we rated it a solid 4 out of 5. The Siena is especially impressive considering its rock bottom price – and today it’s even cheaper as you can get a queen size Siena for just $379 in the brand’s Flash Fall Sale. 

We added the Siena to our official best mattress guide, highlighting it as the top choice under $500. We normally see it on sale for around $399, so today’s sale price of $379 is the cheapest we’ve seen in a while. The sale ends on Thursday 28 September, so don’t sit on this one.

While Nectar normally leads the Black Friday mattress deals, we aren’t sure whether Siena will be making an appearance yet. So if you need a new mattress and like the Siena, now is a good time to buy. 

Are cheap mattresses worth it?

As we said in the beginning of our article, a big price tag doesn’t always equal big sleep comfort. There are a few good cheap mattresses out there that punch above their weight and deliver a nice balance of support and comfort. Some of them, like the Siena Memory Foam and the Cocoon by Sealy Chill, sleep reasonably cool too. Though if you overheat, consider getting a proper cooling mattress instead.

So cheap mattresses are worth it as long as you know what to look for and as long as you don’t expect them to last several years (the average lifespan of a good mattress is eight years). 

Based on our testing and research, we’d recommend considering the following before buying a budget mattress:

• What position you sleep in
• The firmness or feel of a mattress you like best
• Any specific health or sleep issues your mattress needs to help with
• Whether you sleep alone or share a bed
• Does it come on a trial period?
• Are shipping and returns free?
• Is it covered by a warranty and is that a full or limited warranty?

Many of the best mattress in a box brands are now making affordable mattresses, including the likes of Casper and Sealy. Always check the sale terms and conditions before buying, and research trusted mattress reviews such as ours as well as what existing customers have to say.
