Have you ever woken up in the morning with severe lower back pain because the middle of the mattress you were sleeping on had sunk down? This is a classic sign of a cheap, low-density foam mattress.

In the mattress world, the term Density is extremely important. The higher the density, the heavier, firmer, and more durable the foam is in supporting body weight.

When you decide to rent a mattress, don't just be tempted by the lure of "Rent a Mattress for Rp10 Thousand a Day". The mattress might end up being very thin and flat. Let's break down the types of foam to guide your choice!

1. Low/Standard Density Foam Mattresses

This type of foam is usually very light and soft on day one. Manufacturers sell this type of mattress as a temporary, budget option. Its main drawback is: when sat or slept on by an adult (weighing >60kg) on a daily basis, the foam structure eventually loses its shape and won't return to its perfect rectangular form, meaning it goes flat. This mattress is only suitable for babies, children, or very thin people.

2. High Density Foam Mattresses (Highly Recommended!)

High Density foam mattresses are manufactured with dense polyurethane. Their physical characteristic is that if you press them with your hand, the mattress feels springy, pushes back, and is slightly firmer.

The benefits are very clear:

Good for the Spine (Spine Support): The mattress supports your pelvis and shoulders to keep them properly aligned.
Durable & Sag-Resistant: A well-maintained High-Density mattress can stay perfectly flat for over 5 years of heavy use!
