I wanted a softer mattress for my caravan. Since I have at home another in H2 hardness, I have long wondered whether I should here take the H2 as me this is a little too hard. Due to the Kg-information I have yet decided to H2. I can only say that for my size (157 cm) and my weight (48 kg), it is ideal. Who would not be as hard and as I have back problems, it is only recommended. Especially for the unbeatable price. Besides smells I did not notice. Delivery was fast as always. Super seller.
