Question 1

Is the H4 Mattress suitable for side sleepers, or is it too firm?**

Accepted Answer

The H4 is designed as a medium-firm mattress, prioritizing ergonomic support. While some dedicated side sleepers find it perfect, others who prefer a plusher feel note it can feel quite firm initially. There's a common "break-in" period of 2-4 weeks where the materials adapt to your body. If you're a strict side sleeper wanting immediate softness, you might consider a dedicated soft-top model. Many users, however, report the support is excellent for spinal alignment in all positions once broken in.

Question 2

I've read about a smell when unpacking. How long does it last and is it safe?**

Accepted Answer

A temporary odor upon unboxing is common with vacuum-sealed mattresses and is not unique to the H4. This "off-gassing" smell, caused by the expansion of certified foams, typically dissipates within 48-72 hours in a well-ventilated room. Importantly, the foams are certified by Oeko-TEX and CertiPUR-US, meaning they are independently tested and free from harmful levels of chemicals and heavy metals. The smell is not an indicator of safety issues.

Question 3

The mattress is 30.5 cm high. Will it fit my bed frame and sheets?**

Accepted Answer

This is an important practical point. The H4 is a substantial 30.5 cm (approx. 12 inches) tall. You'll want to ensure your bed frame can support this height and that your fitted sheets have "deep pockets" (typically 35-40 cm / 14-16 inches deep) to accommodate it comfortably. Some users with standard sheets have needed to purchase new ones. It's a good idea to measure your current setup before ordering.

Question 4

How effective is the motion isolation for couples?**

Accepted Answer

This is one of the most praised features in social reviews. The 7-zone pocket spring core is designed to absorb movement independently, and the memory foam layer further dampens motion. Couples, especially those with a restless partner, frequently mention on platforms like Reddit that they are no longer disturbed by each other's movements during the night, making it a standout feature for shared beds.

Question 5

What is your return policy if the mattress isn't right for me?**

Accepted Answer

We offer a risk-free trial period (typically 100 nights). We strongly recommend allowing at least 30 nights for your body to adjust to the new support. If you decide it's not the right fit after the trial, you can contact our support team to initiate a return. We'll arrange a free pickup and provide a full refund. The process is designed to be hassle-free, though we advise checking the specific trial length at the time of purchase as terms can be updated.
