How do I stop car seat from sliding forward?

Get some of that material you use between your stacked kitchen pans to prevent them from scratching...the name escapes me right now, but it's kinda spongy and a little sticky.

Eek. Good luck!

NO! If you get into an accident the force is going to be far, far stronger than you tugging on it and any non-slip mat is going to be useless.

Are you sure you have the seat installed properly? Are you using the tether? Do you need a clip to keep the seatbelt tight?

If you can't get the seatbelt and tether tight enough to prevent slipping then get some help from a car-seat installation technician. Generally either the police or fire-fighters have trained people, as do some children's stores. You will have to call ahead for an appointment.

Top tether

An assembly consisting of a top tether strap, attached at or near the top of a CR, together with a length adjuster and a top tether hook, that is used with either a vehicle belt or lower LATCH attachments for complete installation of a CR in a vehicle. For a forward-facing CR, the top tether keeps it from rotating forward in a frontal crash and significantly decreases head excursion. The tether can also improve installation stability, especially when the vehicle belt cannot be tightly secured due to incompatibility problems. Top tethers can also be used with rear-facing CRs (see Top tether, rear-facing), and, in Scandinavian countries, large rear-facing restraints are equipped with a different type of tether attached to the lower part of the CR. LATCH consists of a top tether along with lower attachments that may be configured much like a lower tether.

As of September 1999, new head excursion requirements in FMVSS 213 made top tether straps, either attached or with attachment instructions, necessary on almost all convertibles, child seats, and combination seats sold in the U.S. Those products that can meet the new requirements without a tether have offered them as options. If a CR is equipped with a top tether that is not being used, parents should be encouraged to find or install a top tether anchorage in their vehicle(s). When not in use, the top tether hook and anchorage hardware, if included, should be secured to prevent them from injuring a child in a crash. The correct anchorage location for the top tether can be found either in the vehicle owner's manual or in the instructions provided by the vehicle manufacturer with the tether anchorage kit, available from dealerships. Use only tether anchorage locations specified by the manufacturer. For older CRs, a tether kit, which includes the webbing strap and the means to attach the strap to the CR, may be obtained from the manufacturer. The instructions specify whether it must be attached to the CR frame, an add-on metal rod, or a slot in the plastic shell. It is essential to order the correct kit based on the exact model and date of manufacture.

Some of the hardware in the CR and vehicle kits may be the same, but certain pieces are not interchangeable. If a threaded nut or receptacle is provided in the vehicle, the matching bolt must be used. Using the bolt from the CR manufacturer's tether kit could strip the threads. If the tether bolt is screwed into a small nut, a large washer must be placed between the nut and the back of the mounting surface to keep the nut and bolt from ripping through the hole. The metal bracket (the only visible part of the anchorage hardware after installation) must be shaped so it accepts the hook on the end of the tether strap.

For a comprehensive resource on LATCH, including tether use and anchorage installation, see Stewart et al. 2007.

Take it to the police station and they can show you how to properly install and use your car seat. The officers in my town do it twice a year at the outlets, but we can go to the station at any time and someone will help. They'd rather take a few minutes to show you how to do it properly, than to go to an accident where the baby is in a car seat that wasn't properly installed.

Your seat is not properly installed or not designed for your model of car. Call a fire station or police station (not 911) and find out where you can have your seat properly installed. They will show you what to do.

You can go to any fire or police station and have them take a look at the seat to make sure it is installed properly :)

if it has a separate base that can help. or you can put a towel or something under the carseat also.
