we bought one. very comfy and makes the hard bed in our guest bedroom feel luxurious
Had one a few nights now. Makes a rubbish mattress a lot More comfy can recommend
I know, this is a completely different price tag but I got this one about a year ago. amazon.co.uk/gp/product/B0832GTSPQ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1 Absolutely amazing. So good that we put it on the floor for couple of days when we had guest. Not much of a difference than having it on mattress.
Question is it any good or waste of £30
Only 2.5cm sorry but not worth it. Argos have a 5cm for about £5 more or did last time i looked and its the same one i bought 5-6yrs ago
