Are boxed beds any good?

Whilst beds-in-a-box used to be deemed as a lower quality compared to traditional mattresses, these days they are some of the most advanced and highly-rated beds you can buy.

Of course, whether one is good quality or not comes down to the type of materials that it’s made from and its build quality. If you want a good mattress in a box, look for one that uses high-quality foams, springs or a combination of both. And check the density of the foam and the type and number of coils included.

Higher-density foams are more durable and generally less likely to sag or lose their shape over time, they can also provide better support and have a firmer feel. And when it comes to coils, a higher coil count can indicate better support and are more likely to distribute your weight evenly and reduce pressure points.

However, the type of coil and its gauge will play a significant role here. A higher coil count can boost contouring, leading to more comfortable sleep.
