If you're shopping for a good affordable mattress, here's 3 I recommend

1. Nectar Memory Foam Mattress
Was: from $699
Now: from $349
Saving: up to $700 at Nectar

Best for: Side sleepers, couples, premium benefits

Summary: Topping our guide to the best memory foam mattresses, the flagship Nectar model provides comfortable sleep at an affordable price tag. In our Nectar Mattress review our testing panel found the all-round performance impressive, with this versatile mattress offering a supportive feel that's particularly suited to side sleepers. We rated motion isolation highly, making this a good option for bed sharers who tend to wake each other up tossing and turning. The temperature regulation also scored highly – particularly for a budget-friendly memory foam – but weak edges are a slight disadvantage. As a medium-firm mattress it might be too soft for stomach and back sleepers, but with a 365-night trial, you have plenty of time to test it out before committing.

Benefits: 365-night trial | Lifetime warranty | Free shipping

Price history: Nectar has been running this up to 40% off sale for a little while now, with the current queen price of $649 (from $1,099) live since earlier this year. However, while this might be a Nectar mattress sale we see all the time, the price is still excellent for the quality of the bed.

2. Siena Memory Foam Mattress
Was: from $499
Now: from $199
Saving: up to $500 at Siena 

Best for: Back and stomach sleepers, hot sleepers

Summary: From Resident Home, the brand behind the Nectar at number one, the Siena Memory Foam is one of the best cheap mattresses around. It's firmer than a traditional all-foam bed, as we discovered during our Siena Memory Foam Mattress review, which makes it a good pick for back and stomach sleepers. The edge support also earns high marks, so if you struggle getting in and out of bed, the Siena provides a stable surface to push against. Despite the all-foam build, the Siena lacks the contouring you might expect from memory foam so side sleepers should look for a bed with more cushioning. Or consider adding one of the best mattress toppers, for a hit of comfort that won't break the bank.

Benefits: 180-night trial | 10-year warranty | Free shipping

Price history: The 50% off Siena mattress sale is evergreen, but it's such a hefty saving on a mattress with excellent pedigree that it's always worth shopping. A queen is only $399 (was $799) while you can pick up a king for less than $500.

3. Brooklyn Bedding Dreamfoam Essential mattress
Was: from $274
Now: from $191.80
Saving: up to $344 at Brooklyn Bedding

Best for: Unusual sizes, combination sleepers

Summary: The Dreamfoam Essential mattress is available in a huge variety of sizes, making it a great affordable choice for anyone with a bed frame slightly out of the norm. As well as RV sizes, you can pick up an Olympic queen and short queen, and this versatility landed the Dreamfoam a place in our guide to the best queen mattresses. In addition to width and length, you can also customize the height of your Dreamfoam Essential. For regular adult use, we recommend opting for 10 inches or taller, but the 6 and 8 inch options are suitable for children and occasional use. As to the mattress itself, in our Dreamfoam Essential mattress review our testers found the bed was simple but comfortable, with a medium firm sleep surface that suits back and stomach sleepers. The Dreamfoam Essential is also good for side sleepers, but consider upgrading to a thicker size if you predominantly lie on your side. While it lacks the motion isolation of the Nectar and the edge support of the Siena, this is a strong all-round choice.

Benefits: 120-night trial | 10-year warranty | Free shipping

Price history: There's 30% off all beds in the current mattress sale at Brooklyn Bedding, a step up from the 25% off deal we see through much of the year. This reduces a queen size 10-inch Dreamfoam Essential to $489.30 (was $699). We don't expect this deal to appear until the next major sale day, so now is the time to shop.
