Double Bed and New Mattress

We are selling our wooden double bedframe and mattress together. The mattress is quite new, as we bought it a couple of years ago for our guest room. It has rarely been used. We need this bedroom for our growing family and will need a single bed instead for space. The Mattress is a Harvey Norman Comfort Pocket, hypoallergenic, which costs about 600 euro new. It has no marks and is extremely clean. The bedframe is older than the mattress but very solid and will come apart easily to be rebuilt, as it does not have many pieces (not an Ikea bedframe). Headboard height 110 cm Bedframe width 146 cm Bedframe length, just under 2 meters. Lots of space under bed.
