Nursing chair - to buy or not to buy?

Ha

My baby is 4 weeks old now and I’ve been breastfeeding her in bed at night but even with cushions behind me I don’t feel like I’m supported very well and my back is starting to take a hit for it now.

I’m then also struggling to keep baby in a comfortable position for her to feed so our night feeds are starting to take longer because I’m switching between cradle hold and rugby hold when my back starts to hurt.

I’ve spotted a second hand nursing chair but just wanted some feedback from ladies on here - if you have one, do you use it, do you find it more comfortable?
