As Covid-19 continues to affect our lives, we must continue to do our parts. The well-being of our staff and customers is important to us and as we open up our showrooms we have taken government recommended steps to ensure everyone’s safety. We urge all our clients to call ahead or email us to book an appointment for any visit as we will be limiting the amount of customers in the showroom/warehouse.
