Hi somnolence,
They are a newer brand that was just recently introduced (see here) and one of the partners (Curt Ling) used to be one of the founders of Pure Latex Bliss which makes a range of latex mattresses. Both of the partners also worked with OMI which also makes a wide range of latex mattresses.
Having said that … I would be very cautious about brand shopping in general because you are buying a specific mattress not the brand and all manufacturers have access to the same or similar components and materials. Many manufacturers make a wide range of mattresses that can vary from lower quality and less durable materials to higher quality and more durable materials in a wide range of prices. The name of the manufacturer on the label or the price of the mattress won’t tell you anything about whether a specific mattress is suitable for you in terms of PPP or whether there are any lower quality materials or weak links in the design that would affect the durability and useful life of the mattress (which are the two most important parts of a mattress purchase). There is more about the risks of brand shopping in post #5 here and post #12 here.
While I can’t speak to how any mattress will “feel” for someone else in terms of firmness, “comfort”, or PPP because this is too subjective and relative to different body types, sleeping positions, and individual preferences, sensitivities, and circumstances … outside of PPP (which is all about how well you will sleep on a mattress) the most important part of the value of a mattress purchase is it’s durability and in terms of durability a mattress is only as good as its construction and the type, quality, and durability of the materials inside it (which is all about how long you will sleep well) regardless of the name of the manufacturer or the name of the mattress on the label. In other words I would always make sure that you are able to find out the information listed here so you can compare the materials and components in a mattress to the quality/durability guidelines here and confirm there are no lower quality materials or weak links in a mattress that would compromise the durability and useful life of a mattress before making any mattress purchase. I would also only deal with retailers or manufacturers that are both willing and able to provide you with all the information you need to make an informed choice.
All the Posh and Lavish mattresses use latex and wool quilted covers which are both high quality materials (although they don’t mention the specific type and blend of latex in each layer of their mattress) so there would be no lower quality materials or weak links in any of them that would compromise the durability and useful life of their mattresses.
