Our Verdict: The Purple Plus mattress is best for side sleepers who enjoy a unique, gel-like feel and excellent temperature regulation. It is affordable compared to other mattresses from the brand. However, it only comes in one firmness option and may not be suitable for back sleepers. The Purple mattress lineup has seen significant improvements over the years, with the Purple Plus being a high-end option in the Essential Collection designed for upgraded comfort for side sleepers. The mattress may have a long off-gassing process and a somewhat divisive feel initially, but it provides good support and pressure relief once fully inflated. The Purple Plus features a dual base support foam, a layer of comfort foam, and the proprietary GelFlex Grid material that gives it a unique, responsive feel. The Purple Plus is rated as medium-soft, making it ideal for side sleepers seeking pressure relief. The mattress offers solid edge support and good motion isolation despite its softer construction. It excels in temperature regulation, staying breathable and neutral throughout the night. The Purple Plus is priced on the higher end compared to other brands, but occasional discounts may make it more accessible. The mattress comes with free shipping, a 100-night trial period, and a hassle-free return policy within the first 30 nights.
