Firm vs Medium Soft Mattress: Which Feel Is Right for You?
Mattress firmness is one of the most personal parts of choosing a new bed. A label such as “firm” or “medium soft” can be a useful starting point, but the better choice depends on how you like a mattress to feel, how you usually sleep and what you want from the overall setup.
At OzyDreams, the Pillow Top Bamboo 30cm Mattress – Firm Feel and the Charcoal Bamboo Mattress 20cm – Medium Soft give shoppers two distinct starting points. This guide explains how to compare them without treating firmness as a one-size-fits-all rule.
Quick answer: Choose the feel you are most likely to enjoy night after night. A firmer mattress can appeal to people who prefer a steadier, more supportive surface. A medium-soft mattress can appeal to people who prefer more initial cushioning. Your own comfort and the product specifications should guide the final decision.
What do “firm” and “medium soft” actually describe?
Firmness describes the first feel of a mattress when you lie on it. It is different from mattress height, the type of spring system or the materials listed in the product description. Two shoppers can experience the same mattress differently, so use firmness labels as a comparison tool rather than a guarantee.

When a firm mattress may suit your preference
A firm feel can be a practical starting point if you prefer less sink-in sensation and a more stable surface when changing position. It may also suit shoppers who simply enjoy a firmer mattress feel, regardless of their usual sleep position.
The Pillow Top Bamboo 30cm Mattress – Firm Feel is available in Double, Queen and King. Before ordering, check the selected size, product details and whether the mattress height works with your chosen bed frame.
When a medium-soft mattress may suit your preference
A medium-soft feel can be a good starting point if you enjoy more initial cushioning from the mattress surface. It can feel inviting for people who prefer a gentler first impression when getting into bed.

The Charcoal Bamboo Mattress 20cm – Medium Soft is available in King Single, Double, Queen and King sizes. The broader size range can make it useful when you are furnishing a guest room, teenager’s room or main bedroom.
Use your sleeping routine as a starting point
Think about how you normally settle into bed, whether you share the mattress and whether you prefer a more cushioned or more stable feel. These are useful questions, but they are not strict rules. Comfort remains personal.
- If you enjoy a steadier feel: begin by comparing firm options.
- If you prefer more initial cushioning: begin by comparing medium-soft options.
- If you share a bed: discuss the feel you both prefer before choosing.
- If you have specific health concerns: seek appropriate professional advice rather than relying on a general buying guide.
Firmness is not the same as mattress thickness
A 20cm mattress and a 30cm mattress can differ in profile, appearance and the way they sit within a bed frame. Thickness alone does not tell you whether the mattress will feel firm or soft.
Read our 20cm vs 30cm Mattress Guide to compare mattress height separately from firmness. If you are selecting a frame as well, make sure the total bed height works for your room and everyday use.
Check the bed base too
The frame beneath your mattress matters. Review the product specifications for both items and make sure the selected mattress size matches the bed frame size. A stable and appropriate base helps you make a more informed comparison between mattress options.
