Good question! All beds will have some level of body impression and change in the way they feel over time. Most manufacturers maintain that a bed is defective if the impression is 1.5"-2.0" or greater. Buying directly from the factory at Lebeda gives you a unique advantage in that while your bed may be dipping and isn’t a warranty issue, there are instances were we can still take your bed back to the factory and alter it to make it feel the way you want. That versatility enables us to take care of customers for years and another reason why Lebeda has such a loyal clientele base. Lebeda cares about YOUR comfort.
