Needed a mattress for a new double bed in the guest bedroom (previously 2 single beds).  Purchased this as seemed reasonable price.
Bed was metal frame and slim rods in place of wooden slats and mattress fitted nicely.
However, one person moving, while sleeping, resulted in the other sleeper being rocked about the bed and both sleepers 'rolled together'
Tried mattress on our own bed with slats and was a bit more comfortable with less movement.
Would be ok for occassional use in a strong framed bed.
