I cannot say enough good things about this bunkbed set!! We bought 2 bunkbed sets recently for a beach house.  The first one was nearly half the cost of this one  it shows.  It’s cheap, flimsy, the assembly instructions weren’t very clear... After our experience with the first bunkbed set (also bought on Wayfair) I decided to spend the extra money to get a higher quality bed  it paid off.  The assembly instructions were very clear.  This bunkbed set is nice  sturdy.  The pieces fit together well. The trundle bed rolls smoothly.  A 7” mattress will fit in the full trundle bed.  We liked the ladder at the foot of the bed because it makes making the bed much easier than when the ladder is bolted to the side of the bed  your bottom bunk mattress is actually squished by the ladder (speaking from experience).  If you’re in the fence, pay the extra money.  You won’t regret it!
