It looks quite similar to the one we have, in features and prices.
dd is 16 mo and still uses it, I don't know what age they go up to.
The various heights are good as I couldn't bend over too low at the start (c-section), we're on the highest level now and have been since dd can sit up & pull herself up onto the rails.
The drop rail sounds good but is always up in our house as once the baby is sleeping you do not dare bring it up (the noise wakes the baby up...)
It looks like you need to buy the mattress on top of that.
I bought a few duvet/side thingies/pillow case sets and never ever used them....
