The bed itself is very good. I got the assembly service but it doesn't appear to be that complicated to assemble. Having said that, the guys that did the assembly do do this sort of thing for a living so no doubt that contributed. A very nice, helpful and affable pair they were as well - that always makes a difference.
The bed and matress is a very comfortable combination. The ability to lift and open the base is a wonderful solution to storing the things that are used infrequently; it also provides ample space to keep the summer duvet / clothes in the winter and vice-versa.
One very pleasant thing about the bed is that despite the top of the base being hinged / counterbalanced it does not in any way feel less sturdy or "wobbly".
Two things to be aware of with this type of bed:
Firstly - when turning or flipping the mattress make sure to leave the weight of the mattress on the bed. The arms that allow for easy lifting to access the storage compartment counterbalance the weight of the mattress and so if the mattress is not atop the base, it rather helpfully (and surprisingly) lifts. Can be a little tricky to move the mattress back onto it solo;
Secondly - be aware when opening / closing that you keep an eye out for squatters. It took me a short time to realise where the cat had vanished to and when I lifted the bed to check, there she was. She was also quite adamant about remaining in 'her' new box.
The one thing that does detract from the overall experience is that the pillows & bedding I also ordered are still to materialise. While I understand that sometimes these things can happen (3rd party deliveries, stock availability, simple oversight due to workload and so on) that does not change the fact I am, as of today, still out of pocket with nothing to show for it.
TLDR:
Really pleased with the bed, the delivery & assembly guys were great and these 2 things are what have kept the rating to a 5 in spite of the disappointing lack of the extras I also purchased.
