I am now using Ikea Sultan single bed spring mattress can't remember which range but it gives me bad back ache everyday I wake up.... darn

Although it gives you 25 years warranty, do you really want to take it back to ikea? since we don't own a lorry? and the question is am i still willing to sleep more onto that particular mattress which has given me back ache for more than 2 years?

Depends on your budget?

I'd like my king koil silvery for single bed
