Disgusting. Arrived with a 3 foot yellow urine? Stain ( as pictured) thick black mould in lots of places. A big dent. This "certified refurbished " mattress was clearly a good couple years old. Bought through their eBay shop and they've totally ignored me. The mould is horrendous. The smell, ungodly. The yellow stain appears to be bright yellow urine and 3 foot long. Absolutely horrendous. All this when we unzipped the relatively clean top cover. Black grubby marks throughout also. Please see pictures for proof. Trust pilot, please don't allow them to remove this. I am a genuine customer. Ebay item, from the dormeoshop. Item... 8A0300006034A087 in so pleased we checked under the cover the day it arrived. Also, very very very thin. Lay on it and your back hits the wooden bed slats below, and I'm only slim. Very poor item. These mattresses ( octa pro top of range) at 600 odd pounds are really poor. Please read and unzip your cover when it arrives! Don't risk sleeping on urine and mould! Lots of pics and videos available but, i can't get them to upload, sorry. Thank you
