Rhyme source 4.5 Inch Cold Gel Memory Foam Mattress Replacement for Sleeper Sofa and Couch Beds - Full Size CertiPUR-US Certified (Sofa Not Included)

This product fits perfectly on a queen size sleeper sofa and is very comfortable.

The mattress arrived quickly and fit perfectly. Once it inflated to full thickness the mattress is very comfortable. Our folding sofa bed folded up with no problems.

Very comfortable

Very comfortable, folds into sofa bed easily and is a great improvement to the original spring mattress! J. In Streetsboro

Good thickness and comfortable

It has been more than the 78 recommended hours to wait to full expand. It did not expand fully, and is lumpy and ...dented? Idk how else to explain it. Didn't reach 4.5 inches either. Spots are 2 inches, others are 3. Waste of time and money.

Very comfortable

Purchased this to go on a sofa bed that was already comfortable and this took a good sleep to a great sleep. Its easy to fold and has great firmness.

Colchón firme y resistente. Ptotege bien de la estructura metálica del sofá.

Matelas très confortable pour un divan-lit. Par contre il est préférable de mettre un sous matelas rigide pliable.

Desempacamos el colchón y después de una semana no pudo alcanzar su forma completamente y quedaron algunas porciones aplanadas.. Esto es un grave problema, porque no se puede usar en forma conveniente. No lo recomiendo para nada.

Great replacement mattress. Very comfortable and folds in nicely!

Great customer service! The mattress arrived on time. No smells. I let it ‘air outside’ even still and just lay flat to regain its shape as directed. Unfortunately it was a little short on the listed dimensions, but seller gave a discount for that and so we will keep it and make it work! It does fit into our sofa-bed with no problems! Way better than the old mattress we had. We also bought a support pad for under this foam mattress and that really helps with the comfort level of a sofa bed nicely! I suggest buying this item and a support for underneath.
