Factors that Affect Choosing Latex Mattress Topper Firmness
When it comes to enhancing the comfort and support of your mattress, a latex mattress topper is one of the best investments you can make. But how firm should a latex mattress topper be? This is one of the most frequently-asked questions about latex toppers. The answer depends on several factors, including your sleeping position, body weight, personal preference, and the condition of your existing mattress. In this guide, we’ll explore everything you need to know to choose the perfect firmness level for your latex mattress topper.
Understanding Latex Mattress Topper Firmness
Latex mattress toppers come in different firmness levels, typically ranging from soft to extra-firm. The firmness of a latex topper is often measured using the ILD (Indentation Load Deflection) rating, which indicates how much force is required to compress the material by 25% of its thickness. A lower ILD means the latex is softer and more conforming, while a higher ILD indicates a firmer, more supportive topper.
In addition to ILD ratings, the overall feel of a latex topper can be influenced by its density, thickness, and the type of latex used—Dunlop or Talalay. Dunlop latex tends to be denser and slightly firmer, whereas Talalay latex has a more consistent cell structure, making it feel softer and bouncier. The firmness level you choose should align with your comfort preferences and support needs, ensuring a restful and restorative sleep experience.
Common ILD Ranges for Latex Mattress Toppers
| Firmness Level | ILD Range | Feel and Characteristics |
| Soft | 14-19 | Plush, contouring, best for pressure relief |
| Medium | 20-24 | Balanced support and comfort, ideal for most sleepers |
| Firm | 25-29 | Provides substantial support, good for back sleepers |
| Extra Firm | 30+ | Very supportive, often used for firm mattress reinforcement |
Factors to Consider When Choosing Latex Mattress Topper Firmness
1. Sleeping Position
Your sleeping position plays a crucial role in determining the best firmness level for your latex topper.
- Side Sleepers – Soft to medium toppers (14-24 ILD) help alleviate pressure on the shoulders and hips.
- Back Sleepers – Medium to firm toppers (20-29 ILD) provide adequate spinal alignment and lumbar support.
- Stomach Sleepers – Firm to extra-firm toppers (25+ ILD) prevent the midsection from sinking, which helps maintain proper posture.
2. Body Weight
Your body weight influences how much you compress a mattress topper and can impact the overall feel.
- Lightweight Sleepers (<130 lbs) – Softer toppers provide adequate contouring without excessive pressure.
- Average-weight Sleepers (130-230 lbs) – Medium toppers offer a good balance of comfort and support.
- Heavyweight Sleepers (>230 lbs) – Firmer toppers prevent excessive sinking and ensure proper spinal alignment.
3. Existing Mattress Condition
If your current mattress is too firm or too soft, the right latex topper can modify its feel.
- If your mattress is too firm – A soft to medium latex topper can add plushness and relieve pressure points.
- If your mattress is too soft – A firm latex topper can provide additional support and prevent sagging.

Choosing Between Dunlop and Talalay Latex
Latex toppers come in two main types: Dunlop and Talalay. Each type has unique characteristics that can influence the firmness feel.
| Type of Latex | Characteristics | Firmness Considerations |
| Dunlop Latex | Denser, more supportive, slightly firmer feel | Better for firmer toppers, long-lasting support |
