The Lilian Sofa Mattress review

SofaBedMattress.com is a single-product store run by Mattress Insider, and the Lilian is its only mattress. The pitch is flexibility: you pick a size from 8 stock dimensions or enter a custom width and length, then choose a Contouring Memory Foam or Responsive Latex comfort layer and a Firm or Medium feel, all at the same price. Every version sits on a supportive foam core under a removable organic cotton cover and is built to fold inside a sleeper mechanism. The standout term is the Limited Lifetime Warranty, which also covers custom sizes, against 10 years for most rivals here. The starting price was $299.65 on sale when we checked, down from $461, so watch for the promotion ending. The 365-night trial applies to standard sizes, and returns in the first 100 days are handled by donating the mattress to a charity and sending the receipt. SofaBedMattress.com does not publish layer thicknesses on the product page, which makes it harder to compare than the Deluxe.
