Have I bought pull ups or normal nappies which pull up?

OK, fairly confused about this! DS is potty trained but not at night, so he wears a nappy.
The last few weeks he's been in some Sainsbury's own brand nappies, size 4, and they pull up but are absorbent.
Back home now and no Sainsburys anywhere near here, so DH went to Tesco and bought Tesco's own brand size 4 nappies, but they say on the pack that they're pull up pants.

Are pull ups as absorbent? What I want is a nappy which pulls up (due to being unable to get him to stay still enough!!) but is fully absorbent. Am I right in thinking that 'pull up pants' are a brand and are for potty training so not as absorbent?

I always thought they called them pull up pants as the marketing men's kiddology for the parents to think their child was on the way to being potty trained (but actually as they look and feel like nappies, no baby/child is going to worry how they do up as they're nappies so they're going to wee in them , hence they wear them to an older age). Am sure they're the same as nappies for absorbency!

pull ups are a kind of like pants but in nappy form,with no sticky tabs.They are just as absorbent as nappies.

(have phd in nappies/pull ups as learning disabled dd is still in em at 5.5:()

Pull ups are nappies that you don't need to do up, making them easier to put on an older baby who can stand. I used them for years with my two because they meant that the DSs didn't have to lie still for very long when being changed. We used Pampers Easy Ups and there was no difference between then and the ordinary nappies imo.

We use the Tesco pull-ups for our Dts (19 months) when they don't fancy lying down for a nappy change. Just as god as tabbed ones, in my experience!

Thanks all - I really was beginning to think this was rocket science. (And maybe it is, which makes mavis a top person - but at the circumstances for gaining the knowledge.)
I used washables for DS until he was potty trained (apart from the last month or so where I was all preggo and sick so really couldn't deal with the laundry!) but I now wish I'd posted earlier - the tabbed nappies were quite challenging!
