Double mattress - IKEA Vesteroy firm (Stoke Hill EX4)
A double mattress from IKEA. The type is Vesteroy and it is the firm variant. This was used for my son when he was 1-2 years old. Unfortunately we didn't use a mattress protector, so there are stains from him sleeping with his mouth open. Only used for 1 year, so it is in very good condition.
