Question 1

I've read some reviews mentioning the mattress size is slightly off. What are the exact dimensions I should expect?**

Accepted Answer

While we manufacture and advertise this mattress as a standard 90 x 190 cm single size, it's important to note it arrives in a compact roll. After unboxing and full expansion (which can take up to 72 hours), you may find a variance of 1-2 cm in either dimension due to the nature of compressed foam. This is common with bed-in-a-box mattresses. Most standard fitted sheets will still fit securely. If you have a bed frame or space with absolutely zero tolerance, we recommend checking your exact internal measurements first.

Question 2

Is the 'medium firmness' suitable for side sleepers or those with back pain?**

Accepted Answer

Yes, this is one of its most praised features! The medium-firm feel provides a balance of contouring comfort and essential spinal support. Many users on social media specifically mention relief from back pain. For side sleepers, it offers enough cushioning for shoulders and hips while keeping the spine aligned. If you prefer a very plush, "sinking" feel, you might find it firmer than expected initially, but most adjust within a week.

Question 3

Does the memory foam make the mattress sleep hot, and is there a chemical smell?**

Accepted Answer

The mattress is designed with breathability in mind. The soft, breathable cover and high-density foam structure promote air circulation, and most users report sleeping comfortably cool. Upon unboxing, you may notice a temporary, harmless odor from the foam being vacuum-sealed—this is not harmful (thanks to our CertiPUR-US & Oeko-TEX certifications) and will fully dissipate within 2-3 days in a well-ventilated room.

Question 4

How durable is this mattress, and will it sag over time?**

Accepted Answer

The high-density memory foam core is engineered for durability and resilience. Based on user feedback, the mattress maintains its supportive shape well with typical use. To ensure even wear and maximize longevity, we recommend rotating the mattress head-to-foot every 3-6 months. It's an excellent value-for-money option that holds up reliably, especially for average-weight sleepers and guest room use.

Question 5

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

Accepted Answer

We stand by our product with a customer-friendly trial period. If you're not satisfied, please contact our customer support team within the specified trial window (check your order details for the exact period) to initiate a hassle-free return. The mattress comes with a standard warranty covering manufacturing defects—full terms are available on our website. Our goal is to ensure you find the perfect sleep solution.
