Top Mattress Stores in St Peters

Midwest Clearance Center Furniture and Mattress

This local gem on Salt River Road specializes in overstock and clearance items from major manufacturers. Don't let the "clearance" label fool you - these are brand new mattresses at significantly reduced prices.

I've seen name-brand queens here for as low as $250, and they often have higher-end models for 40-60% off retail. Their inventory changes frequently, so it's worth checking back if you don't find what you want initially.

Mattress Firm Mid Rivers

The national chain brings consistent service and a huge selection to our area. Their sales associates receive extensive training on sleep science, which shows when you're comparing different mattress types.

Expect to pay $500-$1,800 for queens, with regular sales bringing those prices down. They carry all the big names like Tempur-Pedic, Sealy, and Serta, plus their own private label options.

Ashley Store

While primarily known for furniture, Ashley's mattress selection has really improved over the past few years. Their showroom setup lets you see how different mattresses look with actual bedroom furniture, which is surprisingly helpful.

Queens typically run $500-$1,200, and they offer some excellent package deals if you're furnishing a whole bedroom. Their Chime memory foam line offers good value for the price point.

Best for: Customers furnishing entire bedrooms or wanting to see furniture combinations

Mattress Direct

This locally-owned shop on the North Outer Road provides the kind of personal service that's getting harder to find. The owner often works the floor himself and really takes time to understand your sleep preferences and any issues you're having with your current mattress.

Their pricing is competitive with queens ranging from $400-$1,000, and they're willing to work with you on price. They also offer some unique brands you won't find at the big chains.

Best for: Customers who value personal service and local business support

Sleep Number

The adjustable firmness technology here is genuinely impressive, especially if you and your partner have very different comfort preferences. Their sleep assessment process is thorough, though it can feel a bit sales-heavy at times.

Prices start around $1,200 for queens and can go up to $3,500 for their premium models. The technology works as advertised, but you're definitely paying a premium for the customization features.

Best for: Couples with different firmness preferences or those with specific comfort needs

Delivery Considerations

Most St Peters mattress stores offer delivery throughout the metro area, but there are some key differences to know about. Bob's and Ashley typically provide free delivery on purchases over $499, while the smaller local shops often include delivery in their pricing negotiations. Mattress Firm charges a standard $99 delivery fee but frequently waives it during promotions.

For timing, expect 3-7 business days for most in-stock items, though custom or special-order mattresses can take 2-4 weeks. If you're replacing an old mattress, ask about haul-away services - most stores charge $50-$100 for this, but it's worth it to avoid the hassle of disposal. Setup is usually included with delivery, though some stores charge extra for stairs or difficult access. Before making your purchase, use our pre-purchase checklist to ensure you've covered all the delivery details.

Mattress Buying Guide

Understanding Firmness Levels

Firmness is probably the most misunderstood aspect of mattress shopping. What feels "medium-firm" to one person might feel soft to another, depending on your weight, sleep position, and personal preferences. Most stores use a 1-10 scale, with 1 being extremely soft and 10 being rock hard.

Side sleepers generally do best with softer mattresses (4-6 on the scale) that allow hips and shoulders to sink in slightly. Back sleepers usually prefer medium to medium-firm options (5-7), while stomach sleepers need firmer support (6-8) to prevent their midsection from sinking too much. Don't rely solely on the firmness rating - spend at least 10-15 minutes lying on each mattress in your preferred sleep position.

Keep in mind that most mattresses will soften slightly over the first few months of use. If you're between two firmness levels, consider going with the firmer option, especially if you're shopping for a memory foam mattress that will conform more over time.

Size Selection Strategy

Room size is obviously important, but don't forget to measure your stairways, doorways, and hallways before you buy. A king mattress does you no good if it won't fit up your stairs. Queens are the most popular size for good reason - they work for couples in most bedrooms and are easier to move and sheet.

Consider your sleeping habits too. If you or your partner move around a lot during sleep, that extra space in a king might be worth the higher price and space requirements. For single sleepers, a full might seem adequate, but most adults find the extra length and width of a queen worth the investment. Check our detailed mattress size guide for exact dimensions and room planning tips.

Budget Planning

A good mattress is an investment that will affect your sleep quality for 7-10 years, so it's worth budgeting appropriately. That said, you don't need to spend $2,000 to get a comfortable, durable mattress. The sweet spot for most people is $600-$1,200 for a queen, which gets you good materials and construction without paying for premium brand markup.

Factor in accessories when budgeting - a new mattress often means new sheets, and you might want to upgrade your pillows or add a mattress protector. These extras can add $100-$300 to your total cost. Many stores offer package deals that can save money if you need multiple items.

Don't ignore financing options, but read the terms carefully. Many stores offer 0% financing for 12-48 months, which can be helpful for larger purchases. Just make sure you can pay it off within the promotional period to avoid high interest charges. Our budget calculator can help you determine a comfortable spending range based on your situation.

Prefer Shopping Online?

If you'd rather skip the store visits entirely, Sleepology offers a compelling online mattress shopping experience that addresses many of the pain points of traditional retail. Their commission-free pricing means you're not paying extra to cover sales commissions, and their "double-the-difference" price match guarantee ensures you're getting competitive pricing.

What sets Sleepology apart is their Price Predictor tool that helps ensure you're buying at the best possible time, plus their educational approach that focuses on helping you understand what you need rather than pushing specific products. They carry premium brands all in one place, offer white glove delivery, and provide transparent, no-haggle pricing. You can get free delivery with code DELIVERY at checkout.
