Help With identification of this cacti

[jakeypopsicle]

Hi I'm new to the forum and new to owning a cactus. Or any plant for that matter.
I recently purchased this cactus from IKEA (I understand this is probably not the most reputable place to buy a cactus, but what's done is done) and have tried to find out what it is from various websites and have had no luck so far. Hopefully someone here can help me on here with identification?

Many thanks in advance
