This bed is very cute and should serve my purpose well for the guest room . The pros for this product are: 1) it used materials in combination of solid pinewood and manufactured wood, rather than ALL mdf (wood chips), so it should be more durable and re-paintable if need be; 2) there is a quality control in accurate organization of materials list and assembly instruction for the most part; 3) the final product after assembly has an appeal, that is, aesthetically pleasing; 4) it was delivered super-fast without damage in transition.
The cons are: 1) the cost; it's double the price of other trundle beds made of mdf; 2) Assembly requires some handyman skill because of specificity. I would not recommend it to anyone who does not have the patience for precision in assembly; 3) there is a slight miscalculation in design; Or it should have allowed more room in planning the slats. The Spec indicates the width of the bed as 77", but mine came out as 76.5", which made the slats too tight between 4-5 boards even after adjusting for the 1/2" shortage.
Lastly, the instruction in Step 13 is missing the info that you need to drill a hole on the two end slats for two metal dowels. I was glad, however, that the end slats didn't come pre-drilled holes, as I needed to adjust the length of the trundle and the spaces on end slats. Overall, this is a charming product produced with a level of quality control. With a bit of fine-tuning in design and cutting, and possibly in 100% wood, it could be an even more durable and worthy piece of furniture.
