The Basics 4" memory foam mattress topper was a little bigger than the queen mattress I have and stuck out at the corners. They do have a queen short, but I didn't see that offered at time of order.  So, once it is out of the small box it comes in, there is no way to get it back in to return.  In addition, it was very difficult to sleep on, not comfortable at all.  Decided to try to return it, but cost is half of the price. Just stored it away and Wayfair gave me a 20% discount off the order I still have  to pay for. Not great but the delivery fee is almost $39.
