Molblly Pocket Springs vs. Traditional Open Coil Mattresses

Molblly Hybrid Mattresses use pocket springs inside, which offer many benefits when compared to traditional open coil mattresses that are sold online.

Pocket springs consist of individual coils encased in fabric pockets, offering targeted support and minimal motion transfer.  

In contrast, open coil springs are interconnected coils forming a continuous wire structure, providing more generalised support but potentially allowing for more motion transfer.

Pocket springs tend to offer better support and durability, while open coil springs may be more affordable.

Ultimately, the choice between pocket and open coil springs depends on factors like individual comfort preferences, budget, and desired level of support.

Shopping Tip: You can also check out the Silentnight Ferndale 800 Pocket Eco Mattress, which is 25cm deep and has 800 pocket springs inside. It’s a popular Silentnight model priced at £449 or £329 when on sale (for a double size).

1. Construction and materials

The Molblly Memory Foam Mattresses feature multiple layers of foam, including memory foam and high-density base foam. The memory foam layer conforms to the body’s contours, relieving pressure points and ensuring proper spinal alignment. Meanwhile, the high-density foam base offers durability and stability, preventing sagging and extending the mattress’s lifespan.

2. Comfort and support

One of the standout features of the Molblly Mattress is its ability to strike a good balance between comfort and support. The memory foam layer adapts to the sleeper’s body shape, providing personalised cushioning and alleviating discomfort.

Whether you’re a back, side, or stomach sleeper, you’ll appreciate the consistent support and plush feel offered by this mattress.


Additionally, the high-density base foam provides robust support, minimising motion transfer and allowing for undisturbed sleep, even if your partner tosses and turns throughout the night.

3. Temperature regulation

One common concern with memory foam mattresses is heat retention, leading to discomfort and interrupted sleep. However, Molblly has addressed this issue with innovative design features aimed at enhancing breathability and temperature regulation. The mattress’s breathable cover and ventilated foam layers promote airflow, dissipating heat and keeping you cool and comfortable throughout the night. 

As an alternative, you can check out the Slumberland Airclima Mattress collection, by Bensons for Beds, which has 1,000 pocket springs inside and breathable, pressure relieving memory foam. Their price starts at £499.99 for a double size.

The robust high-density base foam ensures structural integrity, preventing sagging and deterioration over time. 

Additionally, the mattress’s resilience to body impressions means you can enjoy consistent comfort and support for years to come, making it a sound investment in your sleep health.

Do Molblly Mattresses have a smell when they are first unboxed?

After unboxing and removing the packaging from a Molblly mattress, a slight smell is usually common. This is due to the CertiPur-US and OEKO-TEX 100 certified foam inside. Ventilate the room by opening a window for a few days, and the odor will dissipate.

Molblly mattresses do not have fibreglass inside, however, you can still check the specifications of the model you’re interested in to ensure it meets your preferences and requirements.
