meddy,
the chairs are super hardy. can definitely withstand up to 70+ kg (that should be approx how much my husband weighs).
caicai,
didn't apply anything on it. just took an effort to keep them clean as far as possible. he was wailing his lungs out for abt an hour after his fingers were clipped by the lift door. to pacify him, i breastfed him, and then pretended to hold the fingers up to "blow" the blisters away. worked for him psychologically. he sort of forgot abt the blisters altogether the next day.
michelle,
thinking if i should get more top and bottom sets. when are you consolidating/closing orders?
