1) Structure & density

• Double layer : supportive base + memory foam to distribute pressure.
• Density : avoid foams that sag; favour support that retains its shape over time.
• Thickness : medium sizes → 8–10 cm; large sizes → 10–15 cm.

2) Size & ergonomics

• The dog must be able to stretch out fully in it .
• Edges : useful for resting the head, but low entry for stiff joints.
• Place the bed in a quiet corner , away from walkways.

3) Cover & hygiene

• Removable cover : machine washable = simplified hygiene.
• Durable fabric : scratching, hair, small accidents; add a mattress protector if needed.
• Non-slip base to prevent slipping.

4) Special needs

• Senior dogs : moderate edges, firm enough surface to stand up on.
• Large sizes : reinforced thickness/support.
• Dogs sensitive to the cold : materials retain heat, warm room.

5) Quick checklist

• Base + memory foam (support + comfort).
• Suitable size (extended dog).
• Washable cover + optional mattress protector.
• Non-slip base, quiet location.
