When shopping for a recliner sofa online, what features should you prioritize beyond the basics?

Buying a recliner sofa online can be tricky. Sure, comfort and looks matter—but what about the hidden details that affect daily use? Think about the recline mechanism (manual vs. electric), frame durability, ease of cleaning, seat depth, and the type of foam used. Then there's delivery, assembly, and long-term maintenance. A lot of people get caught up in the upholstery or how it looks in a photo and forget about how it actually functions. What are your must-check features before buying a recliner online? Any red flags or smart tips for others browsing online?
