Sturdy and really nice but assembling was a real pain! Read that there were missing holes and centre panel had to be removed but both are not accurate. Instructions are confusing and parts are not all numbered so you really need to pay attention otherwise you can confuse parts and think that there are missing holes when in fact you might be used the wrong piece. I am quite please and extension works well, hidden under the other two panels. I would have given 5 stars if the assembling had not been so complicated and long (at least 3 hours).
