We've worked hard to make the best mattress on Earth. To prove to you we stand behind our ground-breaking sleep solutions, every new owner of an Envi® Mattress gets our Perfect Night's Sleep Trial for their first 120 Days of ownership. This means that you can buy an Envi® Mattress and see what the hype is about for up to 4 months in the comfort of your own home. If you don’t like it for any reason at all - we want to know all about it, we'll make sure the return process is hassle-free, and we'll ensure you get a full refund. We know when you try your first Envi, you'll sleep on one for the rest of your life.It's too good to keep to ourselves.
