Ikea Double Bed (Leirvik) with Mattress (Vesteröy)
Bottom sections of the legs feel "slightly wobbly" whilst being assembled.
But once it's all together it seems fine.

Note that I accidentally took the main bed photo before removing the mattress cover. By the time I realised it was too late to put it all back together to re-take the photo. So, for the avoidance of doubt, whilst the mattress itself IS included the mattress cover IS NOT included.

The mattress is less than two years old and has been on a "spare bedroom" bed. As such, it's only been used a few times when we have had guests visiting.
