Writing slopes seem to be the most over-priced item you can buy for your child! Two years on, and I am still smarting! It is A3 landscape size and in the end you need that for writing in an open A4 book or having another page on the desk to reference when writing e.g. reading comprehension.
The bottom lip on the ikea stand causes the child to hold their arm unnaturally highly, and then, quite quickly, their arms begin to ache. It achieves the opposite effect of what you'd use a writing slope for.
A sturdy lever arch file (as Mrz suggests) or maybe even just a ring binder can do the trick. I always suggest to anyone who asks for advice that they start with a level arch file and see if it makes the child more comfortable, and then decide on whether it is worth investing in the writing slope after a week or two. For some it doesn't actually make writing any easier.
Some children don't like using slopes because it makes them different and the desire to not stand out is greater than the need to be more comfortable writing and therefore writing more quickly and for longer.
Although DS1's writing really benefited from the writing slope, we found that there was more to consider than we originally thought. In the end. we found that only having a good pen was the best solution taking into account the twin needs of physical help and discretion.
