Comfy, cheap single mattress

[wowfudge]

Can anyone recommend a cheap but comfy and reasonable quality single mattress suitable for occasional use by a child or an adult? It needs to be something which comes rolled up so it will fit in a small car - I'll either go and buy it myself or have it delivered to work.

try here. i can't remember if it comes rolled up but its reasonably comfy to sleep on. if you call 0800 952 0101 and ask for the 'George support team'. you can call from 7am to 11pm x

Argos sell rolled up single mattresses that sew really comfortable. The isleep range are great.

IKEA mattresses are really decent for the price.
