I've got two suggestions. First, the foam materials; what are they? The last mattress I bought was through amazon and, having researched for a few hours, I came to know some of the basic traits foam mattresses can have (talalay latex, dunlop latex, polyurethane, high density, low density, and ways of mixing those different types within one mattress). Most online buyers will do some research, they need straight up information. You can mention quality and care over and over agian, but if you don't have some believable reason to back it up people can be put off by it. For example tempurepedic's marketing commercials and pamphlets usually mention some kind of micro-bubble foam. Which is bs, but people see that and somehow forget to look for another opinion. It's better if you give me the information than if I have to go out and find the facts or psuedo-facts from somewhere else.
Second, your website shows your "team". It also says you manufacture them yourself; not in those words, but that's the gist of it. There is no way those 6 people meet the demands of manufacturing and all the other things involved in running a product company. Nowhere does it say that the team is the whole company, but mentioning "we" so often puts a spin on the only staff you can see or hear mention of. It makes the reader think we're a small company and we do everything ourselves...and here's our pictures. Show some care for the whole company and everyone involved. I personally think very highly of companies who do that.
