Steer well clear and head to IKEA! Mars bunk with trundle is a very poor quality product; the worst flat pack quality I have ever seen. Built by a flat pack professional (who has built more items very well for me and others). There are 1-2mm gaps between every side panel and couple trundle bed panels and several panel edges also don’t align by 1-2mm. My 5 year old asks if I can stop her bed wobbling and it’s up against walls on 2 sides! If this product meets BSI standards I’ll be very surprised. Happy beds not offered satisfactory resolution after considerable correspondence. Don’t seem to appreciate the significant inconvenience this causes when they ask to dismantle and repack for a refund. Offered a pathetic £40 discount which in no way makes up for the poor quality and amount of time communicating with their team and BSI and TS - who agree the discount is poor and they should assist with dismantling and removal. Raised complaint to Trading Standards and BSI (you will need to name the distributor Julian Bowen Ltd who are responsible for BSI approval)and suggest others affected by this product do the same. Happy beds should remove this product from sale given the feedback is mounting from consumers. Hopefully BSI will be along soon to inspect the product again. If you have been affected by this product contact your local trading standards office and BSI for advice.
