Mattress Firm knows that upgrading a child's bedroom from a nursery to a “big-kid" room can be an overwhelming task. With daunting costs and endless kid's room ideas online, knowing exactly where to start can be tough. But with  seasonal sales popping up, now is the time to save!

Before you stop into one of your  nearest Mattress Firm locations to select a mattress for your son or daughter, take a look at these five tips for decorating your children's bedroom. We're here to help you create the best  “big-kid" bedroom for your little sleeper — without breaking the bank.

1. DIY It

Whether you are a master crafter or a first-timer, breaking out the sewing kit and paintbrushes can help save you some cash. From stitching pillows to painting the walls, there are a million ways you can take charge in the decorating process.

And with so many simple craft projects available online for kid's bedroom ideas, you will find no lack of inspiration!

2. Size-up For Less

When deciding which size bed to get your child, taking the long view can help save you cash. While your child may be small now, their first big-kid bed will likely be around until they graduate high school. Choosing a bed that will fit them now and when they're fully grown can help you save for years to come.

3. Keep What You Can

Redecorating does not need to mean replacing everything. There are many items that can easily be repurposed from a nursery to a “big-kid" bedroom with little to no effort. Whether that means a new coat of paint or a fresh sanding, salvaging furniture and accessories can mean big savings and an easier redecorating process.

Although bigger items, like the mattress and bed, will need to be replaced, keeping things that are familiar to your child will help them feel most comfortable in their new room.

4. Don't Rush

Decorating can be overwhelming at times, especially when on a budget. But just as a house is not built in a day, don't feel like you need to get every piece for your child's bedroom at one time.

Gathering the little details over time can help the room to feel more authentic and sentimental, and when you finally do finish decorating, you will know that each piece has been chosen with love of your child in mind. Mattress Firm recommends reading reviews and checking customer ratings on anything you're considering for the refreshed space.

5. Have Comfort in Mind

Any bedroom should be a sleep sanctuary, so to ensure your child adjusts best to their new room, including a bed and mattress that will support and comfort their growing body.

Old toys, blankets and other trinkets that your child is attached to will help them feel right at home in their new room. And with a new room, comes a new bed. Finding a mattress that is just right for them will ensure they are getting the best sleep every night for years to come.

If you're having trouble deciding where to start, remember the importance of a good night's sleep. Your child will be healthier and happier after a solid snooze, so stop by your  nearest Mattress Firm and start your “big-kid" room transformation.
