Which is better for a couple's main bed?

Product A. It comes in King and Cal King, is 12 inches thick and uses pocketed coils, which isolate motion better than the bonnell coils in B.

Which is better for a sofa bed?

Product B. Its 6-inch Twin profile fits sofa beds and tight frames, and it is the cheaper, steadier buy at $84.88.

Is A worth the extra over B?

Yes if you need a larger, thicker bed. A has reached $118.00, but you get pocketed coils, a pillow top and a washable cover that B does not list.

Product A is the safer bet for daily use. Its 12-inch pocketed-coil build has more material and better motion isolation than the 6-inch bonnell build in B.

Do they feel the same?

Both are medium-firm hybrids with memory foam over coils, but A adds a pillow top and pocketed coils, so it feels plusher and quieter than B's flatter bonnell top.

Which is better for a child's room?

Product B suits a low Twin bed or bunk. Product A is listed as suitable for children with spine dysplasia and is the better pick if you want a fuller mattress.
