New startup business - The GlamSwag

Hi my name is Rebecca Johnson. I have created a product called a GlamSwag. A Glamswag is essentially a take anywhere bed or throwbed.
It is the size of a single bed. It is filled with a cloud like doona, 50% duck down and 50% polyclustre fibre. They are covered in a variety of materials. Our new range is french flax linen. The covers are removable and can be thrown in the wash.
The uses are varied - you can lie on them or under them. Take them Glamping, Camping to the beach, picnics, outdoor cinema, movie nights, sleepovers just to name a few.
They are proving to be quite difficult to market.
We have used many influencers which proves effective but not for long.
We did hire a digital marketing company, spent a lot of money and literally made one sale. Which was very disappointing.
We use social media - instagram, and facebook. I have joined a company where I get weekly advice re hashtags, content etc.
Our website is beautiful as my husband is a photographer, as are our photos on instagram and facebook.
I would appreciate any advice on how to drive more sales
