Kathy Smith—February 13, 2025
I bought this to replace an old spring type mattress in a sofa hide a bed.....which everyone complained about! Kept company from staying too long...lol. I placed this over the accordian type boards made for hide a beds. With both the boards and mattress topper the bed is super comfortable. I ordered to same size as the old mattress and it folded back into the couch perfectly. A great purchase. Read more

Nice replacement bed mattress...
Apocalypto_Altapete—February 9, 2025
This 4" queen sofa bed mattress replacement is a fantastic upgrade for anyone seeking extra comfort. the certipur-us certified memory foam provides excellent pressure relief, making it perfect for sleeping or lounging. the mattress is ultra-soft, and the washable cover is a great bonus for easy maintenance. it's a good size for a queen sofa bed, measuring 72"x60", and provides a significant improvement in sleep quality. however, it's not as thick as a traditional mattress, so it may not be suitable for everyone, especially for those needing a firmer surface. overall, a solid option for enhancing comfort on a sofa bed.

Makes the old pull out feel better than new
Nic—September 30, 2024
I've never been a fan of pull out couches, but they serve a purpose. We've had one for a very long time and rarely use it, but recently I needed it while we had work done on the master. I slept on that old weak-springed mattress for two days... two days too long. So, I was very happy to give this a shot. This mattress has more loft to it (to borrow a term from down jackets) than the old spring mattress. It has to be squished pretty firmly to put the couch away. I gave it one night and found that it provided a firm feel versus the old mattress that felt more like a metal hammock. 1000% better. The bar isn't high, I know. But this revives the guest bed and brings it up to a respectable level for a low price. Read more
