I understand a divan is usually better than a frame with slats. The problem is I would like something relatively low, to fit better in an attic conversion (even though I realise the mattresses are quite big). I also find divans in general a little ugly.Warren Evans give the following description of their bed frames:"All our bed frames - except Divans - have a flat, slatted base. A slatted base allows your mattress to breathe, keeping you cooler, your mattress healthier and reduces allergens such as dust mites. Each slat is made from solid pine. The slats are spaced approximately 1.5 - 2 inches apart, they are 5.5” wide and there are 10 slats on each bed frame. The slats on 2'6 to 5'0 size frames are ¾” deep. Super king sizes - 5'6 and 6'0 frames - are 1.5” deep. Due to the substantial width and depth of our slats, a centre support is not needed."Do they sound like they would be suitable for your mattresses?Thank you.
