RTG's pre-purchase customer service was amazing. I spoke to one of their team on the phone twice, who talked me through the modularity of the Solitaire beds very patiently as I tried to understand how I might be able to buy future kits to "build up" in the future and whether to instead buy the full lot up-front and just build the starter for now, storing the other parts for the future. In terms of the product, I have two small negatives that make this a 4 and not 5-star experience/product overall: 1) As per a recent review from another buyer, there are no instructions for installing the side-board. Since having this safely fitted is key for my 2 year old as he makes the transition to his big bed (and any other child I would assume), having to make this part up on the fly yourself, is clearly not ideal. The response from RTG to the other poster said that RTG would "pass [the] comments on to the manufacturer". That doesn't sound to me like they're making this right any time soon; more just passing the buck a bit. In the mean time, why not create and post a pdf version on the RTG website? That would be very easy to do. N.B. Overall it took me a solid 1.5 hours to build this bed alone. For context I would consider myself an experienced amateur furniture assembler having built maybe 20 IKEA and other pieces over the last 15 years. 2) The bed is extremely heavy (I think the packaging said 50 or 60 kilos). Many people might not care about that, but it's worth knowing. It's a well known fact that MDF is heavy so I could (should?) have known based on the product description which did state it was made from MDF Overall, very happy, I am only leaving this constructive feedback to 1) get some a small but essential improvement in terms of assembly instructions and 2) make others aware of the weight.
