## Description

Heavy Duty Sleeper Sofa Support Board (48x48 - Full Size) Reinforced Wood Sofa Bed Support, Pull Out Couch Mattress Board, Sleeper Bar Shield, SleeperSaver by Meliusly

## Features

- As Recommended by New York Times Wirecutter - The PATENT PENDING Meliusly Sleeper Shield makes any sofa bed more comfortable. Most pullout sofa beds are made with steel support bars that you can feel on your back through the mattress. The Sleeper Sofa Bar Shield makes sure the bars are covered, effectively preventing discomfort that is common with this piece of furniture.
- Easy to Use and Store - The sofa sleeper board comes folded up in the dimensions 48 x16 x 2''. When the sleeper sofa is expanded, the board can simply be unfolded and placed between sleeper bar and mattress. After use, the board can simply be folded up and stored away.
- Extra Sturdy 1/3 inch thick reinforced wood panels combined with Oxford polyester that helps hold the board as well as the mattress in place.
- Helps firm up sagging mattress and cushions - The sleeper sofa board makes sure that the weight is distributed more evenly across bed/sofa, effectively helping firm it up and extending the furniture life. The dimensions unfolded are 48 x 48'' - ideal for Full Size Sofa Beds.
- At Meliusly we are a small, family-owned business that focuses on providing solutions to unsolved problems. We pride ourselves in our customer service and appreciate your purchase. We would love to hear about your experience! NOTE: The sofa bed displayed in the main image is NOT INCLUDED!
