Has anyone bought a decent mattress from groupon?

[BigFatBloomers]

I need 2 single mattresses for our spare room but they have to be less than £100 each. It looks as if there are some really good bargains on Groupon.
Can anyone recommend a good one? I don’t want to have them delivered to discover they’re like cardboard.

I could really do with a little advice here please.

I haven't but I've recently bought two excellent mattresses on eBay. Search for bedzonline. They are good quality, brand new and next day delivery. £90 a double.
NB I don't work for them!

I’ll have a look. Thanks bluejelly

What did you buy bluejelly?
There seems to be quite a range on there.
I think we want ones that are pocket sprung but with a bit of padding on top. Definitely not completely memory foam but my son has one that is topped with a thin layer of foam which seems comfortable.

I just can’t understand the enormous range of prices of mattresses. Do you really get what you pay for or does it come down to brand?

So that sounds like one not to buy then shitwithsugaron. Thanks!
