Hello all,

What should I look for in the materials/construction/joining of the frames and springs of a sofa versus a sofa sleeper made by mid-line brands?

For seating purposes does a sleeper hold up as well as sofa in the same line?

How long is the average lifespan of a midline sofa or sleeper based on excellent care by the consumer?

What Brands are considered midline? (not junk but not the best-I'll probably use it 10 to 15 years)

Is Palliser considered midline?

Thank you folks for helping out a south Arkansas girl. Jan
