Obviously, your box will not be this small if you order an Amazon mattress

A certification from this company means the foams in your mattress meet certain minimum health and environmental standards.

They’re also tested for low VOC emissions.

Even budget mattresses will usually have a sleep trial of at least 90 nights.

But it’s not that straightforward when buying a mattress from Amazon.

Those that do have a trial require the customer to jump through certain hoops to activate it.

However, even with this premium option, your returns window won’t change.

This is to ensure it’s comfortable and offers decent support.

… anything else to look for?

There’s one final indicator of quality, that’s perhaps the most useful of all.

The spec is foam density.

The denser the foam, the better the quality, and the more durable it will be.

High-density foams cost more.

That’s for a budget mattress.

Moving into mid-range, you’d be looking for a density of around 2.5lb.
