Customers find this product to be very comfortable and a great fit for various bed frames, including trundle and toddler beds. The size is generally well-received, with many appreciating its suitability for children's beds and guest rooms. However, some customers have experienced issues with the thickness and fit, with one review noting it hung off a twin bed frame and another receiving a 4-inch mattress instead of a 6-inch. Despite these concerns, the product is considered a good value for its price.
