### **Pros and Cons of buying a Audi AU018787 (2017 2023 A4 S4 A5 S5 RS5 Rear Seat Bolster Cushion Set x2)**
#### **Pros:**1. **Enhanced Comfort and Support** The bolstered rear seat cushions provide better lumbar and side support, reducing fatigue during long drives. This is particularly beneficial for passengers in sporty or high-performance Audi models, where seating firmness is often prioritized over plushness.
2. **Improved Ergonomics** The design helps maintain proper posture, reducing slouching and potential back strain, which is useful for both passengers and drivers in models like the S5 or RS5 where the rear seats are typically firmer.
3. **Compatibility with Multiple Models** The part number (AU018787) is designed for a range of Audi models (A4, S4, A5, S5, RS5) from 2017 to 2023, making it a versatile upgrade if you own or plan to own one of these vehicles.
4. **OEM Quality** As an Audi original equipment manufacturer (OEM) part, it is built to the same high standards as factory-installed components, ensuring durability and a proper fit.
5. **Aesthetic Improvement** The bolstered design can give the rear seats a more premium and tailored appearance, enhancing the overall cabin feel, especially in models where the stock seats may feel too basic.
6. **Potential Resale Value Boost** Upgrading to OEM bolstered cushions can make your vehicle more appealing to buyers who prioritize comfort and luxury, potentially increasing its resale value.
7. **Easy Installation** These cushions are typically designed to be a straightforward swap for existing rear seat cushions, requiring minimal tools and time for installation.

#### **Cons:**1. **Cost** OEM parts, even for cushions, can be expensive compared to aftermarket alternatives. The price may not justify the upgrade if the stock seats are already comfortable for your needs.
2. **Limited Availability** Since this is an OEM part, it may not be readily available at all dealerships or online retailers. You may need to order it directly from Audi or a specialized parts supplier, which could involve shipping delays.
3. **Size and Fit Concerns** While the part is designed for multiple models, slight variations in seat dimensions between different trims or years could lead to a less-than-perfect fit. For example, the RS5 s rear seats may have different contours than the A4 s, potentially affecting comfort.
4. **Weight** Bolstered cushions are often heavier than standard ones, which could slightly reduce fuel efficiency in fuel-injected models (though the impact is negligible in most cases).
5. **Durability Over Time** High-quality OEM parts are durable, but like any upholstery, the cushions may wear out over time, especially if the vehicle is used frequently. Replacement may be needed after several years.
6. **Potential Overkill for Some Users** If you or your passengers already find the stock rear seats comfortable, the upgrade may not provide a noticeable improvement and could be seen as unnecessary.
7. **Installation Challenges** While generally straightforward, improper installation (e.g., misalignment or improper securing) could lead to discomfort or even damage to the seat mechanism over time.

### **Conclusion:**The **AU018787 Audi rear seat bolster cushion set** is a worthwhile upgrade for owners of 2017 2023 A4, S4, A5, S5, or RS5 models who prioritize **comfort, ergonomics, and a premium feel** in the rear seats. The OEM quality ensures a durable and well-fitting solution, and the bolstered design can significantly reduce fatigue during long drives. However, the **higher cost and potential overkill for those with already comfortable stock seats** may make it less appealing to some buyers.
If you frequently carry passengers or drive long distances and find the stock rear seats lacking in support, this upgrade is **highly recommended**. For casual drivers or those who don t prioritize rear-seat comfort, the expense may not be justified.
### **Recommendation:**- **Buy if:** You own one of the specified Audi models, frequently use the rear seats, and want improved support and posture. The OEM part ensures reliability and a seamless fit.
- **Skip if:** Your budget is tight, the stock seats already meet your comfort needs, or you prefer aftermarket alternatives that may offer similar benefits at a lower cost.
- **Alternative Consideration:** If cost is a concern, explore **high-quality aftermarket bolstered cushions** (e.g., from brands like Recaro or custom upholstery shops) that may offer comparable comfort at a reduced price.
Ultimately, this is an **excellent investment for those who value comfort and luxury** in their Audi s rear seats.
