I just can’t recommend Shoptimizer enough. I feel like I’m on a first-name basis with some of the crew, they’re just so unbelievably helpful, no matter what the question. Their products are also so beautifully well made and easy to maintain, they’ll last for years to come.
Every order from Shoptimizer has been an amazing experience. their site provides lots of detail so I know exactly what I’m getting and their customer support is just outstanding. I needed to swap an item for a different size and they arranged everything for me within 24 hours.

What our customers say
So far so good, went up to the show room and they were very helpful in giving information to help us choose my chosen seats. They didn't badger me whilst trying them out or to buy the most expensive ones, supplied me the information I asked for and help me with the correct fitment. I haven't yet received my seats but I can't wait to do so! So far so good 🙂
Great little showroom to try a range of fixed bucket seats which is essential for a snug fit. Gave honest advice and didn't try to oversell which is great. Bought a pair of Mirco RS1 with custom material and colours - great seats for a great price! Just received my BS7 Auto-style seat. Goods took a lot longer than original estimate but the team gave updates when I queried during the COVID-19 upset. Seat arrived but poorly packaged which was ripped in a number of places. Seat was fortunately wrapped in bubble rap which had been ripped away from the top of the seat but seat undamaged. Seat quality is good for the low price. Have e-mailed them photos of the package damage on arrival and I would suggest the packaging is beefed up to avoid possibility of damage in transit. Nevertheless I would recommend them and put the delay down to COVID.
