90cm W Height -Adjustable (Set of 2)

The picture is a little misleading: If you look at the picture (underneath the top shelf) you can see some sort of middle bar that supposed to give extra support to the shelf, but mine didn't come with any of them.

Delivery was quick but needed You Tube to assist with the building of the unit as instructions were impossible to follow. Once figured out assembly was swift with 2 people. No mallet included in the box but luckily we had one. Parts were missing had to notify Wayfair, was resolved quickly. Some parts were plentiful.

Brilliant shelving unit gives so much more space and very sturdy

Those are excellent. Easy to out together and very sturdy. Only note that if you're planning to put them in the basement, you'd need to prime the cardboard shelves.

Easy to assemble

Fantastic value. Sturdy.
