If you're looking for a low-profile medium-firmness pocket-sprung mattress, this is definitely one of your best choices as it offers the best price:comfortability for its type. It is more expensive on average, however, a personal anecdote of mine is to never skimp when purchasing a mattress; here you are not paying too much, and not too little.
Even though times are far from normal at the moment thanks to COVID, I would still recommend going in-store and trying out the Sleepmatch machine so you can shop based on your own recommended preferences--as I did--because what is comfortable for you, and for myself, is purely subjective. However, as mentioned above, if it is a medium-firmness pocket-sprung mattress you know you are looking for, this is the one I recommend; after trying out all of the recommended mattresses in store, this one in particular left an impression far above the others I had tried prior, including in other retailers.
As for my decision of it being low-profile... I live on the shorter side of life and while my bed frame itself is low to the floor, the mattress itself stops at around my kneecaps meaning I do not need to abseil out of bed, I can also sit on the edge of the bed with my feet comfortably on the floor.
