I would agree that using solid wood is a step up from veneered particle board in terms of longevity and durability. But they still use the same joinery system, those pin-and-latch things plus unglued dowels as alignment pins. These do offer the ability to disassemble the furniture in the future but every time you lean on, bump into, or otherwise apply a racking load to the piece, all that force is going to get transferred to the tiny amount of wood fiber surrounding those screw threads holding those latch pins in place, and eventually they’ll start to loosen. They’re still not as solid as a good old fashioned glued mortise and tenon, dado or dovetail joint.
Ikea has a lot of chip board furniture but they also have some decent solid wood furniture for a good price.
It’s usually pine but still for the price it’s a decent quality furniture that could last for a good time in good condition.
