What are the load-bearing limits for marble or granite outdoor loungers?

When selecting marble or granite outdoor loungers, understanding their load-bearing limits is crucial for both safety and longevity. Marble and granite are durable natural stones, but their weight capacity varies based on thickness, design, and support structure.

Marble Outdoor Loungers:

- Typical load-bearing limit: 300–500 lbs (136–227 kg) for slabs 1.5–2 inches thick.

- Thinner or intricately carved designs may have lower limits.

- Requires proper sealing to prevent cracking under heavy loads.

Granite Outdoor Loungers:

- Stronger than marble, with limits of 400–600 lbs (181–272 kg) for 1.5–2-inch slabs.

- Less porous, making it more resistant to weather and weight stress.

- Reinforced bases can increase capacity.

Factors Affecting Load Capacity:

1. Thickness: Thicker slabs (2+ inches) support more weight.

2. Design: Solid, flat surfaces outperform curved or delicate designs.

3. Base Support: Metal or reinforced frames enhance stability.

4. Maintenance: Regular sealing prevents microfractures that weaken the stone.

Tips for Longevity:

- Avoid exceeding recommended limits to prevent cracks.

- Use cushions to distribute weight evenly.

- Store indoors during extreme weather to preserve integrity.

For heavy-duty use, consult manufacturers for custom-built options with higher load ratings. Both marble and granite loungers offer luxury and durability when properly maintained.
