1. Siena Essential Memory Foam Mattress: twin was $149 now $109 at Amazon
Siena is among the most reliable affordable sleep brands on the market, so if you're shopping for a new bed on a very tight budget, this is our top pick. Although a cheaper and thinner mattress than the flagship design we praised in our Siena Memory Foam Mattress review, we predict this affordable all-foam mattress will deliver similar firm support and the same excellent value for money. Regular Siena mattress sales means this is never an expensive bed, but just $199 for a queen (was 279) matches the lowest price we've seen.

2. Amazon Basics 10" Memory Foam Mattress: twin was $176.65 now $150.14 at Amazon
The Amazon Basics Memory Foam Mattress has a lot going for it — beside the low price. It's available in two firmness levels, adding some variety to this budget bed (although you'll have to pay extra for the medium-firm.) Customer's praise the cozy cushioning of the plush feel, which is a feature we look for in all the best mattresses for side sleepers. And it's OEKO-TEX certified, promising a bed that's better for the environment. In the current sale a 10" queen is $242.51 (was $285), matching the deal we saw on Black Friday.

3. Novilla Hybrid Mattress in a Box: full was $200.99 now $178.49 at Amazon
The best hybrid mattresses pair strong springs with cushioned foams to create a balance of support and relief. Novilla also adds a pillow-top; a plush top layer that brings a touch of luxury. Reviewers find it good value for money, although some note indentations in the foam stick around for a while (this isn't unusual for a cheap mattress but it can tarnish support.) Currently a 10" queen is only $184.44 (was $216.99) and comes with a 100-night sleep trial. Unfortunately, the twin size isn't discounted but at just $154.99, it's still a bargain.
