My parents have never had a lot of money, but they needed the best affordable mattress they could get and invested a substantial amount of money because they wanted something that would support restorative sleep that we all need to live healthy lives. Unfortunately, they made 2 critical mistakes and ended up with a dud mattress that sagged after a few months and gave my dad back pain when he slept on it. The sad part is this could have easily been avoided by just understanding some basics about 2 specific mattress properties. You see, it's not about the money you spend, it's about understanding the build materials and the fit for your body.
What are those 2 factors you need to consider? I won't keep you waiting.
- Body Fit - Here at SquishMat, we firmly believe that the most important factor to consider when purchasing a mattress is how that mattress interacts with your unique body. There are $5000 mattresses out there that will feel far worse than a $300 one because the firmness and support are tuned for a completely different build of person. It's not about how much you spend, it's about the fit.
- Build Quality - One place where mattress manufacturers often try to cut corners is with low density foam layers. Even though high density foams last a lot longer and don't wear out as quickly (especially under big and tall people), it's cheaper to manufacture low density foams and most people don't think to check. Don't be fooled! A cheap mattress that you have to replace every year because of poor quality, sagging foam layers is not a bargain. SquishMat has you covered with build construction data in an easy to digest visual. We'll also recommend a minimum foam density threshold (which depends on your specific bodyweight).
Don't worry if build construction sounds complicated and scary, we've made it super simple with the SquishMat quiz where you can spend 2 minutes and receive a free (no signup) Squish Blueprint of the KIND of mattress to look for and a list of mattresses that score closely with your specific profile.
The best affordable mattress is not the cheapest box
If you've landed at this article I assume you already have some idea that price AND value are inputs to the "affordability" formula of a mattress. I mean, you don't want to get a cheap air mattress for $50 just because it's the cheapest option. Longevity, quality, and your personal body fit are vital considerations when making this decision. Please don't purchase a $300 mattress without first verifying a mattress will clear these thresholds. Again, checkout the SquishMat quiz that will give you a free and easy printout for your build and needs at whatever price point you're looking at.
Spend on fit, not features
The features that drive sleep quality — correct firmness for your position and weight, a supportive core, durable foam — are not always the expensive ones. The price tends to climb with covers, branding, and exotic materials that feel nice in a showroom but do not change whether your spine stays aligned. Get the fundamentals right at a low price and you will out-sleep buyers who spent twice as much on the wrong firmness.
Think about longevity
Longevity of a mattress depends on the types of materials used. The mattress my parents purchased quickly sagged because it didn't have a high enough foam density in the comfort and transition layers. I'm not even necessarily picking on that mattress, it could be a fine option for a different body, but especially if you're a heavier person mattresses will degrade a lot faster if they aren't built up to snuff. A baseline to look for is polyurethane foam that is at least 1.8 lb/ft³ or if memory foam at least 3.0 lb/ft³. This matters less for lighter individuals but foam density is a useful proxy for longevity and quality. Make sure you get the best quality for you dollar and not pay just for brand markup.
