We haven't used this desk for too long, so we can't comment on the set's sturdiness or writing surface durability.  Hopefully, the wood & finish is hard enough such that writing that goes off the paper doesn't mar the surface.

I will reserve the 5th recommendation star for after the desk & chair have had some usage.  Right now we're very pleased with our purchase.

Our vision therapist recommended that we get a desk with a slanted top, and now we are recommending this desk and your website to her.
