Absolutely delighted with the bed! It arrived a week earlier than the predicted delivery, although, with the current Covid chaos, I realise that could have been because you had to be cautious about dates. The packaging was robust, and all the parts were present. It's a nice design, particularly the trundle, and is extremely well made, with nicely- finished weld joints. The colour, though more ivory white, than simply white, suits the bedroom decor perfectly. I found the assembly instructions straightforward, although I think the detailed pictograms could do with being a bit larger. We had kept good quality mattresses from previous beds, and, although they are 2" deeper than the 4" you recommend as the maximum, the trundle still slides effortlessly under the bed on its natty little wheels.
All in all, a lovely piece of bedroom furniture, at a very good price. Well done, Wayfair.
