[This review was collected as part of a promotion.] The Serta Five Star 8-inch mattress in a box offers a convenient and budget-friendly entry into the world of Serta comfort. Designed for ease of setup, it arrives compressed in a box, quickly expanding so you can enjoy a good night's sleep almost immediately. This mattress typically features a medium comfort level, aiming to suit a wide range of sleepers, including back, stomach, side, and combination sleepers. It often combines a supportive innerspring coil system, which helps with durability and motion isolation, with layers of Serta's PillowSoft Aire Foam and PillowSoft Foam for enhanced cushioning and pressure relief. Some models also include a gel foam band for zoned support, particularly beneficial for the lower back and hips. While its 8-inch profile might be on the thinner side compared to some luxury mattresses, it still aims to provide a balanced feel of support and comfort. Its affordability and easy delivery make it a popular choice for guest rooms, children's beds, or those looking for a comfortable mattress without a significant investment. However, some users note that while it's rated as "medium," it can lean towards the firmer side for some sleepers, and like many mattresses in a box, it may require a day or two to fully decompress and reach its intended firmness.

[This review was collected as part of a promotion.] I have to say that I was super impressed with this mattress from delivery to set up. You just open the box and cut open the plastic, and the mattress starts to expand. I gave it a couple of days before I tried it out, but both my son and I have slept on it, and it is super comfortable. When I need to replace my youngest sons mattress I will definitely be purchasing a Serta.
