Our take on the 4in Portable Mattress Topper, Tri-Fold Mattress Pad

This is a 4-inch polyurethane foam topper for a queen mattress, built to add a firm cushioning layer over an existing bed. It folds in three and comes with a zippered carrying case, so it stores flat or moves between rooms. The cover is removable and spot clean only. At $89.99 at eBay as of November 6, 2026, it sits at the low end of its recent range across the 5 stores that price it new.

What reviewers say

  • 4.6 / 5770 ratings

Rated 4.6 out of 5 from 770 ratings, buyers mostly report the topper adds noticeable firm support and folds away easily. Complaints center on the initial foam smell and the wait for full expansion.

What people mention
  • FirmnessMixedBuyers describe it as firm support rather than soft cushioning, which suits some sleepers and disappoints others.
  • ExpansionMixedOwners say it needs two to three days to puff up fully, and a few found it never reached a full 4 inches.
  • OdorCriticisedSeveral buyers mention a foam smell that fades after airing it out.
  • PortabilityPraisedThe tri-fold shape and carrying case make it easy to store or move between rooms.
  • Cover careMixedThe removable cover is convenient, but spot cleaning only limits how fresh it stays.
